Why Does Battery Light Go On And Off While Driving?

A key component in your car is the battery. If the battery is not charged enough, then the car won’t start. How can you know if your battery is good or not? Well, you can test it, but you can also rely on your battery indicator light working properly.

What does it mean though when your battery light on your dash goes on and off though? Does it mean that the battery is going bad?

Well, read on to find out exactly what it means when the battery light goes on and off while driving and also what you should do about it.

Why does Battery Light go on and off While Driving

Why does Battery Light go on and off While Driving?

Battery Light

The battery light serves two main purposes in your car. One is to let you know when there is an issue with the battery, but the other is to let you know if there is something wrong with the alternator.

When the battery light goes on and off while driving, it means you are having some sort of issues with one of these two things.

Normally it is a good idea to check these things out as soon as possible because if either stop working properly, then you will be left stranded.

The battery light on your dashboard is important to look out for a while driving. Sometimes it can be hard to notice it come on as well because it might only blink on for a second or two before going back off. Other times it may stay on longer.

When does it come on?

Depending on when the battery warning light comes on might help you figure out what is wrong. If the light comes on when just driving normal on a smooth road, then it is most likely more of an issue with the alternator not putting out enough charge or not working properly.

On the other hand, if the light comes on when you hit a bump in the road or are going around a curve, then the problem is more likely to be a connection issue with a wire.

This is because a bump or curve can cause a wire that is barely connected to shift and lose connection. The reason your car doesn’t just die when the connection is lost is that your car can run off the battery charge for a while.

Also, if the alternator is working right, then it can put off enough charge to run the car even if the battery is not connected.

Alternator issues

So, now we can get in-depth more on the possible issues that are happening when your battery light goes on and off while driving.

The first and worse one is that the alternator is not working properly. An alternator normal doesn’t just die and stop working.

Instead, it malfunctions and stops working slowly. This means that it will work, stop, and work again and sometimes it will do this quickly, while other times it will be longer between the cycle.

This is why your battery light might come on for a bit when the alternator isn’t working and then go off when it starts working again.

It is important to check your alternator if your battery light starts to blink on and off

The alternator is a key part of your car because it helps take mechanical energy from your car and converts it to electrical energy to recharge the battery, so the battery can start your car again the next time it is needed too.

If you don’t have a working alternator, your car will eventually stop working. If it goes all the way out, then your vehicle will die pretty quickly, and you will be stranded.

This is why it is important to check your alternator if your battery light starts to blink on and off. The first thing to check with the alternator is to make sure all the wires are connected properly.

If there are any loose wires, then tighten them. After making sure all the wires are connected, you can test the alternator.

Testing the alternator is easy to do. All you need is a voltmeter. Hook the voltmeter up to the battery and see what the reading is. It should be at least 12 volts.

Then start the car and see what the reading is. The reading should jump up to around 14 volts if the alternator is working right.

If the reading does not move up or if the number starts to drop, then the alternator is not working properly and will need to be repaired or replaced.

You can most likely need to take your car to a shop and have this done unless you are a mechanic and good with cars. If the alternator is fine, but you are still having the battery light come on, then it is time to check the battery itself.

Battery Issues

The first thing you should do when checking the battery is to make sure all the wires are connected tightly. If the wires come loose for moments while driving, then that can be why the battery light is coming on and then going off.

One key thing to do when checking the wires tightness is to also make sure that they are clean. If the connection is dirty, then this can affect it as well. Clean off the battery terminals when checking the wires to make sure there is no corrosion on them.

After checking the wires, you can check the battery. If you haven’t already connected a voltmeter to the battery when checking the alternator, then you can do that now.

The reading should be at least 12 volts. If it is less than that, then the battery is not holding a charge and will need to be replaced. If it is, then you can go to any local auto tool shop, and most will test your battery for free.

More: You can use the best battery maintainer to charge your car battery in ways that avoid the potential damaging effects that can be caused by other charger.

They will hook a device up to it, and the device will make sure that the battery is working and charging right. The device can also normally check the alternator as well, so it isn’t a bad idea to have them look at your vehicle even if you have checked the alternator with the voltmeter yourself. This way you will know for sure all your issues are taken care of.

Conclusion

After checking the alternator and the battery, you should have the problem found of why your battery indicator light keeps coming on and off while driving.

Normally it is a failing alternator, but if it mainly happens when hitting bumps, then it could be as simple as loose wires. Luckily for you, you now know the possible reasons why your battery indicator light keeps going on and off while driving and you also know what to do about it, so if it happens to you, you can get the problem fixed before getting stranded somewhere from a bad battery or alternator.

What Does Battery Acid Smell Like? Why Do You Smell? Is It Safe?

So, you may have an odd smell in your car or garage and not be able to figure out where it is coming from. Well, depending on what that smell, smells like, then it might be coming from your car, mower, or something else battery.

In this article, we will talk about what battery acid smells like and also touch on what it means when you are able to smell the battery acid coming from a battery.

Read on to find out exactly what battery acid smells like and if different types of batteries have different smells.

What Does Battery Acid Smell Like

What Does Battery Acid Smell Like?

Reasons for bad smells?

So, before getting into detail on what battery acid smells like, we will first cover why you might smell battery acid in your garage or car. There are a few reasons why you might smell battery acid.

The first is that you might have had a battery get damaged and crack or bust. This can happen for a variety of reasons. If you drop a battery from high enough, then it might break the case and cause battery acid to come out.

Another reason why a battery might start leaking though is because it has burst. A battery can burst from overcharging or getting too hot. It is most common to happen if you leave a battery connected to a continuous charge.

Overcharging is bad for your battery. A battery tender is smart and will not overcharge the battery. So that is why best battery tender is the way to go if you are going to keep the battery on a charger for a long term.

That is why pulse chargers are better to use, and charges that shut off when the battery is full are the best. If you have a damaged battery, then it is important not to use it anymore.

Another reason why you might smell battery acid is if the battery takes to water. Some batteries you have to add water too because it evaporates over time.

These kinds of batteries are not sealed, and you have to open them up and pour water into them to keep the acid mixture correct. If you don’t, then the mixture will become wrong and cause the battery to start to smell like battery acid.

If you start to smell battery acid and have this type of battery, then you will just need to open the battery up, add water, and it should stop smelling and start working right again. It is important to keep water in it so it will work right and not damage the battery.

The last reason why you might smell battery acid from your battery is that the battery just may be bad. As batteries age, they will start to smell like battery acid. This is just something natural that happens as they break down.

The chemicals can only be charged so many times before they stop working right and when they stop working right, they start to smell more.

If your battery is a sealed one and the case isn’t damaged, but it is smelling, then it just means that it is old and needs to be replaced. If your battery isn’t holding a charge or dying frequently and you smell a funky smell, then it is probably your battery.

There are a few reasons why you might smell battery acid

What Does Battery Acid Smell Like?

So, now that you know what it means when a battery smells like battery acid, you are probably wondering even more what battery acid smells like. Well, depending on the type of battery and the person smelling it, it can smell like a couple different things.

One of the most common explanations for the smell of battery acid is that it smells like sulfur. If you don’t know what sulfur smells like, then most people would say that it smells like rotten eggs.

What do rotten eggs smell like though? Well, if you have been lucky enough never to have to smell rotten eggs, then the closest answer to what it smells like is a boiled egg only worse.

If you don’t know what boiled eggs smell like, then you can make one to get an idea. Rotten eggs and sulfur have a strong and distinct smell and once you smell it once you will recognize it, but if you haven’t smelled it before, then it is hard to describe.

The other most common thing that people say battery acid smells like is vinegar. That is because most battery acid is or has sulfuric acid in it and that has a similar smell to vinegar.

Vinegar has a strong sour smell that can sometimes almost burn the inside of your nose if you have it to close to your nose when you smell it. It has a bitter smell to it.

If you don’t know what vinegar smells like, then you can get some and smell it or just think about how pickles, coleslaw, or other food items with vinegar smell to get an idea and realize that battery acid smells strong than this because it is not diluted by other things.

Is it safe?

The last thing we will touch on now that you know that it smells like is if it is safe. You might be worried to remove a damaged battery that smells bad, but really battery acid is not that harmful.

Most are diluted, so it has a PH of zero. This means it won’t hurt you if it gets on you. Just make sure not to eat or ingest any battery acid, but if it gets on your skin just wash it off, and it won’t hurt you.

It is still important to dispose of batteries properly though, so if yours smells and you are replacing it be sure to dispose of the old one correctly.

Conclusion

So, now you know what battery acid smells like. You know that it normally smells like sulfur or rotten eggs or it can smell like vinegar depending on how your nose works.

You also now know what it means when you can smell the battery acid of your battery and what you should do about it. You know that it is safe to replace the battery yourself even if it smells bad and that you just need to dispose of the old battery correctly.

While battery acid smells bad it isn’t bad for you to inhale, so you don’t have to worry about any health concerns if you walk into your garage and smell these smells.

Just remove the problem and let the garage air out. Now you know what might be causing funky smells in your garage or car that you can’t find and even more importantly you now know what battery acid smells like.

What Does It Mean When Battery Gauge Goes Up And Down?

A key component in any vehicle is the battery. If the battery is not working right, then the rest of your car will not work right either. The main problem that happens with batteries is that they lose charge or stop charging effectively over time.

As batteries age, they struggle with holding a charge. Some vehicles have a battery gauge on the dash and sometimes the needle jumps around.

Does the needle jumping mean your battery is bad? Well, read on to find out the answer to that question and to find out what it really means when your battery gauge goes up and down.

What Does It Mean When Battery Gauge Goes Up And Down?

What Does It Mean When Battery Gauge Goes Up And Down?

Battery Gauge

Before going into detail about what it means when your battery gauge jumps around, we will first talk about what the battery gauge on your dash actually is.

Not all cars have the battery gauge on the dash, but it is a useful thing to have because the battery gauge is essentially a voltmeter that is always connected to your battery.

A voltmeter is a tool used to get the reading of how much power is in your battery. The needle may move some while driving, but in reality, the needle shouldn’t move much while driving if everything is working right.

That is why it is a concern when it does jump around while driving.

Why Shouldn’t Battery Gauge Goes Up And Down?

You may be wondering to yourself why the needle shouldn’t move while driving. You may be thinking there is power being taken from the battery by the radio, headlights, and other parts of the car while driving, so shouldn’t that make the needle go down?

Well, this is true that power is being taken from the battery, but power is also being given to the battery while driving. That is the purpose of the alternator.

So, does the needle in the battery gauge jumping around means the battery is bad. No, it actually typically means that you have a problem with your alternator.

Alternator Problem

Your alternator is responsible for taking extra mechanical power from the engine and turning it into electrical energy to recharge the battery or keep it charged. Using best battery tender to do that is excellent decision.

The needle jumping means that the battery isn’t getting the same amount of charge consistently.

The reason the needle jumping doesn’t mean that the battery is bad is that if you have a battery not holding a charge that will only cause the needle to not go up as high on the gauge, but it won’t cause the gauge to jump.

What causes the gauge to jump is that the charge of the battery is changing and this can be quickly or slowly depending on the problem with the alternator and if it is cutting out and dying or something else.

The first thing to Check

The first thing to check when you have your cars battery gauge jumping around is the serpentine or alternator drive belt. The belt is what connects the engine to the alternator, and if the belt is not working right then, the alternator won’t work right either.

When checking the belt you want to check two things. Those two things are the wear on the belt and also its tightness. If the belt is starting to look old, then that can cause the tension to change while driving.

If you see any visible damage or wear on the belt, then it is a good idea to change it. Changing the belt could solve all your problems with the battery gauge jumping.

If the belt does not look wore out, then the next thing to check is how tight it is. The belt needs tension to be able to transfer the power from the engine to the alternator.

It does this by spinning along with the engine and turning a wheel on the alternator. If the belt is loose, then it may slip and this will cause the alternator wheel not to spin and will, therefore, cause the alternator not to work.

You want to make sure the belt is tight, so all the parts will spin. However, you don’t want to tighten it over because this can make it hard to spin for the opposite reason. Also, having the belt too tight can lead to it breaking or wearing out sooner.

Testing Alternator

Battery Gauge Goes Up And Down

The easiest way to test the alternator at home is to connect a voltmeter to the battery

If the belt seems fine and it is the correct tightness, but you are still having issues with the battery gauge jumping, then you will have to test the alternator.

The easiest way to test the alternator at home is to connect a voltmeter to the battery. The battery should read around 14.4 volts with the car running and not fluctuate.

If it is reading less than this, but not changing, then the battery is weak, but the issue isn’t the alternator.

If the reading is jumping, then you will need to have your alternator checked out by a professional because it isn’t working right. It could be as simple as a bad wire or connection, or it could be that your alternator needs replaced.

Corrosion

Before condemning the alternator though, one other thing that can cause the battery gauge to go up and down is if the wires aren’t connected well or are corroded.

It is important to keep your wires clean and connected tightly to the battery. Clean off any corrosion and tighten down any loose wires before replacing the alternator unless you know for sure it is bad.

Bad connections can cause reading spikes, and it is a lot cheaper to clean and tighten wires than to replace the alternator

Conclusion

Now you know though what it means when your battery gauge jumps up and down. You know that it doesn’t mean that the battery is bad, but instead normally means that you have an issue with the alternator.

You should understand better why that is the case and you also know some things to check and ways to fix the problem. You know to check all the wire connections and clean any corrosion.

You also know to check the alternator belt and replace if worn or make sure it is tightened correctly. Lastly, if neither of these things solves the problem then you know to test the alternator and replace it if bad.

Your battery is key to driving your car, so you want to make sure it is charging right before you get stranded somewhere and if you notice your battery gauge jumping, then you should have things taken care of right away.

Different Kinds Of Hidden Kill Switches And How Do They Work?

There are a lot of anti-theft features in cars these days, but would be thieves can get pass them if they really want to steal your car, so this leads to the question of is there any way to stop a thief from taking your car?

If locking the doors, having your car alarm, and having an anti-theft system won’t work, then what else could you possibly do?

Well, the answer is you could install a hidden kill switch. In this article, we will take an in-depth look at what a kill switch is, how to properly use it, and also the different kinds of kill switches.

Read on to learn everything you need to know about hidden kill switches in your vehicle.

Different kinds of hidden kill switches and how do they work?

Different kinds of hidden kill switches and how do they work?

What is it?

Before getting into the different types of hidden kill switches, we will first discuss what a hidden kill switch is. A hidden kill switch is a switch that you have to press to complete a circuit, so your car is able to start.

The reason why it is hidden is so that no one knows where it is, so they don’t know to press it. The thing is you can go about hiding one in different ways which we will discuss later.

There are also a number of different types of kill switches which can be installed and we will break down each one below.

Types of kill switches

The five main types of kill switches that you can install into a vehicle are:

  • Fuel-Line Shut Off Valve
  • Car Battery Disconnect Switch
  • Remote Control Car Battery Switch
  • Fuse Box Kill Switch
  • Ignition Wire Kill Switch

We will go into the detail of each one below and what it does and how it works.

1. Fuel-Line Shut Off Valve

The first type of kill switch we will look at is the fuel-line shut off valves. This type of kill switch will prevent fuel from getting to your engine which is a sure fire way to make sure your vehicle won’t start.

The perk to the fuel-line kill switch though is that the engine will still crank, but just not have enough fuel to turn over.

This means that to a car thief it will just seem like your car is having engine trouble and they are most likely not going to take the time to try to figure out how to steal a car with engine trouble, so while it will keep them from stealing your car, it will also deter them from trying to figure out a way to get the car started.

The way the fuel line shut off valve works is that it is a valve that you install directly into the fuel line. You do this by cutting a chunk of the fuel line out and then put the kill switch in.

The kill switch has a knob that you turn, and in one position it is open, and gas will flow thru normally, but in the other position it is closed, and gas will not go thru.

The downside to this kill switch is that you have to get under your car to turn the knob to open the fuel line. This means you probably don’t want to use this kill switch for a daily driver because you would constantly be under the car to open the valve before you could start your car.

There are five main types of kill switches

2. Car Battery Disconnect Switch

The next kind of hidden kill switch is a better one for a daily driver. It is the car battery disconnect switch.

You still have to open the hood most of the time to turn this one on and off, but that is still better than crawling under the car each time.

You don’t always have to do this though depending on how you connect it and wire it.

You can have the wire run so the switch can be mounted somewhere inside the car and while most of these are knobs that turn some are switches or some require keys.

The way the car battery disconnect switch works is you unhook the negative car lead and then connect the kill switch to the negative battery terminal directly.

You then feed the negative lead into the kill switch. When the knob is turned one way, the circuit is complete, and the car will function and start as normal.

If you turn it the other way though, then the car will not have power. This means when someone goes to start the car it won’t make any sound at all because the starter will not have power.

This will make the thief think the battery is dead. Another downside to this kind of kill switch though is you will have to reset your clock and radio presets every time after using it because they stay in memory with the power from the battery.

That is why one of the other kill switches to come might still be a better option for you.

By the way, If your battery is not dead, try to recharge it with the best battery tender.

3. Remote Control Car Battery Switch

The next kind of hidden kill switch is another one that goes on your battery, but this one doesn’t have a knob to turn. Instead, it is activated with a remote that you can keep on your keys.

This is nice because you don’t have to go under the hood all the time to turn it on and off and also it is nice because you can activate it anywhere.

This means you don’t have to turn it on if you don’t want and can turn it on at a moments notice if you see suspicious activity and want to keep your car safe.

Also, it is nice that you can activate it with your remote because this means you can do it secretly which is one of the main points of a hidden kill switch.

Kill switches don’t do any good if a thief knows it is there, so being able to trigger it and no one notice is a great bonus.

The way the remote control battery kill switch works is that you connect electromagnetic solenoid valve terminal to your battery similar to the other car battery disconnect switch we have covered.

Then when you press a button, it uses a strong magnet to move a metal piece on the inside that either opens or closes the circuit.

If it is in the open position, then the car will not start because it doesn’t have power from the battery, but if it is in the closed position, then the car will start like normal.

The nice thing is this device only draws power for a few moments after pressing the button. Pressing the button sends power to one of the magnets or the other, but once it is activated power is not used to help the magnet hold the circuit opener or closer.

This means that it won’t drain your battery just by having it hooked up.

4. Fuse Box Kill Switch

The next kind of kill switch still deals with removing power from your vehicle, but it doesn’t do it directly at the battery.

Instead, it kills power to the fuse box. Some people just prefer to pull a key fuse such as the ignition fuse and then replace it when they want to drive, but depending on where your fuse box is and how much you drive this can be annoying.

If it is your daily driver, then it is easier and generally better to just install a fuse box kill switch. Also, by using a switch, it makes it less noticeable and thus more effective.

The way a fuse box kill switch works is you run a fuse into your fuse box that when it is activated the fuses will not work.

When it is not activated the fuse box will function normally. They are not that hard to install and only take a few parts and tools.

The nice thing is you can run the wires to the switch wherever you want so you can mount the switch wherever. This means that you can have it inside the cabin and even mount it to the dash or somewhere to make it look cool.

If you want your car to look more spy like this is one way especially if you install dummy switches.

A thief won’t know to look for a fuse box kill switch, and if they see a random switch or two, they won’t know what it is for or the combination for them.

These reasons are why a fuse box kill switch as a hidden kill switch is a very effective method and easier than pulling fuses all the time.

A hidden kill switch is just an added layer of protection from getting your car stolen

5. Ignition Wire Kill Switch

The last kind of hidden kill switch we will cover is the ignition wire kill switch. This one goes straight to the source and puts a break in the ignition wire so your car won’t start.

The way it works is you cut your ignition wire and then hook the wire to each end connector of a switch. When the switch is flipped one way the circuit is complete and the other way it is broken.

This kind of kill switch is nice because again you can hide the switch inside the car and no one will know it is there. Being in the car makes it easy to activate every time and keep it hidden.

The key to installing an ignition wire kill switch properly is to make sure that you look at a wiring diagram for your vehicle.

This way you know you are cutting the right wire. Once you have the wire cut, you can crimp the ends to the switch or solder it for a better connection.

You can then mount the switch wherever you want in your car. An ignition wire kill switch will again make a burglar think the car is dead because it won’t make any sounds if they try to turn the key.

Who should use a hidden kill Switch?

So now that you know about the different kinds of hidden kill switches and a rough idea of how to install one, the next question you may be having is who should use a hidden kill switch? Well, the answer to that is anyone.

A hidden kill switch is just an added layer of protection from getting your car stolen, and you can actually install more than one if you really want peace of mind.

They are especially a good idea though if you leave your keys in your vehicle a lot. This might be because you forget them or you might have a delivery job or something where you stop and go a lot.

Anyone that has a habit of leaving your keys in the car can benefit from a hidden kill switch if you use it right.

You also might want one if you live in a busy city or an area with high crime. This way you can keep your car safe and slow down and deter a thief.

Lastly, if you have a vehicle that sits a lot, then you might want to install a hidden kill switch especially if it sits at an area you aren’t at often such as a vacation house.

This is because thieves know when people aren’t around and what vehicles don’t move much.

Also, if you aren’t home, they have more time to be able to steal it, so having a hidden kill switch to stop this can save you from coming back to a vehicle missing.

Conclusion

Hidden kill switches are a great way to keep your vehicle safe on top of the anti-theft system your car already has.

You can use them in conjunction with your current system and can actually install more than one type for adding protection.

Now you know the basics to install a hidden kill switch, and you know the five most common types.

You know that you can stop the fuel with a fuel-line shut off valve or you can cut the ignition wire directly and install a switch with an ignition wire kill switch.

You also know that you can cut power to some or all of your car to keep it from getting stolen using a fuse box kill switch or a battery disconnect kill switch.

There are a variety of hidden kill switches, and they all have their perks and negatives and now you know what they are so you can decide what kind of hidden kill switch is right for you and your needs.

Temperature Gauge High But Car Not Overheating: Why And What To Do?

Your car has a handful of gauges on the dash, and it is important that they all work right because they tell you the key things about your car.

Some of these gauges it is pretty easy to understand why they are important such as the fuel gauge because you need to know how much gas you have so you don’t run out, but others can be a little harder to understand why they matter such as the RPM gauge or engine temperature gauge.

Well, in this article we will help explain and break down the temperature gauge and what it means when it is reading high, but the car isn’t overheating.

Temperature gauge high but car not overheating: Why and what to do?

Temperature gauge high but car not overheating: Why and what to do?

More: Overcharging is bad on your battery. A battery tender is smart and will not overcharge the battery. So that is why best battery tenders are the way to go if you are going to keep the battery on a charger for a long term.

Purpose

So, before going into why your temperature gauge might be reading hot, we will first briefly cover why it is important. The temperature gauge is responsible for monitoring how hot your engine is and let you know.

Normally your temperature gauge should read around the middle, and this is normal. It means your engine isn’t too hot or too cold. Yes, issues can happen with your engine if it is too cold as well as if it gets too hot.

If your engine gets too hot though, then that is when real damage can happen because the seals can break or the head can crake from the engine overheating.

That is why it is a good idea to pull over and stop if the engine temperature gauge is reading hot because this means that the engine is too hot, or does it.

Well, most of the time the temperature gauge works correctly, and when it is reading high the engine is overheating, but sometimes the gauge messes up.

Read on to find out what else could be wrong if the gauge is reading high, but the engine is not overheating.

Common Reasons

There are a handful of common reasons why your temperature gauge might be reading high.

We are going to list them out for you, and you can jump to a specific section if you think you know the issue you are having or you can read about them all in order if you don’t know what might be wrong. The common reasons for a high-temperature reading are:

  • Low Coolant or Air in System
  • Broken Temperature Gauge
  • Failed Temperature Sensor

There are more reasons for a high reading, but they will normally cause your engine, and this article is only focusing on reasons why you might be getting a false reading.

Low Coolant or Air in System

The most common reason for your temperature gauge to read hot is that the engine really is overheating. This can happen for a variety of reasons, but the most common is low coolant or air in the system.

If your gauge is reading hot, then make sure your engine really isn’t overheating and make sure you have coolant. Also, if you have just had your coolant changed or flushed, then make sure air didn’t get in the system.

If you have checked these things and really think that your engine isn’t overheating, then you can move on to some of the other causes of a temperature gauge reading hot, but it is important to take the reading serious first to prevent damage to your engine before you just think it is a false reading.

Broken Temperature Gauge

A broken temperature gauge

A broken temperature gauge

The next thing that might cause your engine to read as though it is overheating when it isn’t is a broken temperature gauge.

The temperature gauge is made up of moving parts, and anything with moving parts can sometimes break. There are a few possible ways that the temperature gauge might be broken.

The first is if you did overheat your engine and the needle somehow got stuck in the hot section. Over time gunk might get into where the needle is, and this could up cause the needle to get stuck.

If it had never moved to the hot part before and they did, then it might have got in to build up causing it to get stuck there after overheating for real.

Another way that the temperature gauge may be broken is that one of the stepper gears in the gauge may be broken. The gauge has different gears inside of it that are responsible for moving the needle.

Over time these gears can wear and if one breaks then the needle may move incorrectly. One of these two issues could possibly be occurring leading to a broken temperature gauge that is giving a false high reading.

Fail Temperature Sensor

Another reason why the temperature gauge might be giving a high reading when the engine isn’t overheating is that the temperature sensor may have failed or been failing.

The temperature sensor is responsible for measuring the temperature of the engine at any given time. If the sensor has died, then it may not be sending out reading, and the car could respond with giving a false high-temperature gauge.

Also, if the sensor is dead, it may give off a random reading instead of an accurate one. A false reading might also happen if the sensor is damaged or dying. The sensor could easily get damaged while driving if something hit it or it got debris on it.

Also, if the wires are damaged or it has a short, then this could cause a false reading. Cleaning and checking your temperature sensor is a good idea if you get a false high-temperature gauge reading.

What to do When Temperature Gauge High But Car Not Overheating?

If your engine is not overheating, but you have been getting a high-temperature gauge reading, then what should you do.

Well, we have already mentioned that you should check your temperature sensor.

Make sure that it is clean and working right. Also, check any of the fuses that go along with it to make sure they aren’t messed up.

If the temperature sensor is working right, then the next thing will be to check the mechanical parts of the temperature gauge.

Make sure that the needle inside the temperature gauge isn’t getting stuck and that all the gears and moving parts are clean. Also, when checking to make sure they are clean also make sure that they are not broken.

If these two things are fine, then you really should start looking at reasons for an overheating engine because chance is your engine really was overheating.

Conclusion

So, now you know why your temperature gauge might be reading high even when the engine isn’t overheating.

You know the most common reason for an overheating engine is lack of coolant, but you also now know that sometimes the temperature gauge might give false readings.

These false readings normally come from the gauge being broken due to parts becoming wore and broke or from the needle getting stuck. You also know that false readings can also be caused by a failed temperature sensor.

If you are getting high readings without an overheating engine, then be sure to check the temperature sensor and mechanical part of the temperature gauge.

If those things aren’t the problem though, then your engine might have really been overheating, and you need to get it checked out to prevent major damage to your vehicle.

How Many Miles To Reset Computer On Car?

So, you need your car’s computer to reset and it won’t. You have been driving it for what feels like a bunch of miles, but it still won’t reset. What can you do about this?

Well, read on in this article to find out exactly what you have to do to get your car’s computer to reset.

After reading this article you will have a better idea of how many miles you will need to drive your car to get the computer to reset, but more importantly, you will know the conditions required to get your car’s computer monitoring to reset.

How Many Miles To Reset Computer On Car?

How many miles to reset computer on car?

Why do you need it to reset?

So, some of you may be wondering why you might need your computer to reset. Well, there are two possible reasons why you might want this to happen.

The first is a common reason, and that is that you are trying to get your car to pass carbon inspection. In order to pass your car has to run certain checks and not put off any codes.

If you went to the testing place and they connected their scanner and told you that you failed because the computer hasn’t reset, then that might be why you are here now wondering how far you have to drive your vehicle to get the computer to scan all the systems.

The other reason why you might want to get the computer to reset is that you had a code trigger or you had a mechanic tell you something was bad on your car and you want to make sure that is actually the case before having something replaced or fixed.

Sometimes your car can throw codes out of the blue and for no reason, so if it isn’t something major you can reset and clear the code and then see if the computer sends the same code again.

If it does, then that means the part related to the code probably is bad, but if you have been driving for a while and the computer has done the checks, and it doesn’t resend the code, then you know you don’t need that part replaced.

How far to drive?

So, for passing emission test how far do you have to drive before it is ready to pass the test. Well, the answer is it depends. It all depends on how you are driving the car because certain conditions have to be met for the car’s computer to run the check on the different sensors.

For some people, it is ready to go after about 50 miles, but for others, they have to drive much farther upwards of a couple of hundred miles sometimes. This is because the system has to make sure the vehicle is safe thru a variety of readiness monitors.

Depending on the make and model of your vehicle it could have to perform up to eleven different readiness monitors to make sure all the sensors are working right and that the emissions are correct.

How to know if ready?

So, how can you know that your car is ready before taking it to get tested? Well, to do this you have to have an OBD2 scanner and plug it into the OBD2 port normally below the steering wheel.

You then go to the emission output section, and it will read with one of three outcomes. “Ready” which means that the car has run the required readiness monitors and that you can pass the emission test, “not ready” which means the car still hasn’t run the required test or “not applicable” meaning your vehicle doesn’t have self-monitoring system.

You have to have an OBD2 scanner know that your car is ready before taking it to get tested

How to Get Car to Check Itself

So, how do you get the car to run the readiness monitors if it is in the “not ready” mode? Well, most people think that that means you have to drive the car a bunch, but that is actually not the case.

It is actually about the conditions that the car is driven in that triggers the monitors. To get the OBD2 drive cycle to begin, you must start with a cold start. That means if your car didn’t cool down below a certain threshold from your last trip, then it won’t do a check.

The coolant temperature must be below 122 degrees Fahrenheit, and the air temperature sensor must be within 12 degrees of the coolant to get an OBD2 drive cycle to start.

If that requirement is met, then the ignition must not have been left on before the cold start because this may cause the oxygen sensor not to check.

If he is also meet, then the next thing to do is to let the car idle for two and a half minutes with the air conditioner, and rear defrosts turn on.

After the two and a half minutes have passed, you can turn the AC off and rear defrost off and then accelerate the car to 55 miles per hour. You want to make sure to accelerate under moderate constant acceleration and then let the car cruise at 55 miles per hour for three minutes.

After the three minutes have passed you want to begin slowing down, but you don’t want to use the brake or clutch if in a manual.

Instead, you just want to coast and slow down naturally until you are down to 20 miles per hour. Once you reach this point, it is time to accelerate smoothly back up to 55 to 60 miles per hour. Once at that speed cruise for another five minutes.

Then you can begin to decelerate again without braking or clutching and come to a complete stop. This is full should count and trigger as a full drive cycle for your vehicle.

When your car running in long time, you should have best battery tender for car to recharge your battery, it’s important things, your car won’t start if battery is dead or low battery.

How many drive cycles?

So, how many drive cycles do you have to do before your car resets? Well, with most cars you need about three drive cycles to be done.

If you really need to pass the test soon, then you can do short drives like this all in a row once the car has cooled down enough, but you need to make sure to wait at least a few hours between drives to make sure the car is cool enough.

If you are trying to reset the computer to see if a part is bad, then you really don’t need to worry about forcing the car’s computer to run a check. If the part is bad, it will trigger the light quickly enough, and if it isn’t bad, then the check engine light won’t come back on.

Normal driving will allow for a drive cycle to occur, but it is important to remember that when it comes to getting your vehicle’s computer to reset it isn’t how far you drove it, but instead the conditions you drove it in.

Conclusion

Getting your car’s computer to reset is an important thing, especially if you really need to pass your emission test. That is why it is good that you now know how your car checks the different emission parts and uses a drive cycle that tests all the sensors during a drive.

You know that to get a drive cycle to activate you have to have a cold start and then accelerate and decelerate a few times before stopping and turning the vehicle off.

Also, you now know that there is no magic distance to drive to get your computer to reset. For some people, they can get the required number of drive cycle in as little as 50 miles while others may drive a few hundred before getting the drive cycles conditions met.

Now you know to the secret to getting your car’s computer to reset so you can pass an emission test and not get the “not ready” indicator the next time you go for emission test. You also know how to check it yourself with an OBD2 scanner to make sure your car is ready to pass before going to get the emission test.

Blower Motor Not Working On Any Speed?

One of the common luxuries most cars have these days is an air conditioner. This convenience helps keep you cool in the summer.

Another thing that most cars have today is a heating system to help keep you warm in the winter or cooler months. These to things do the opposite of each other, but they have one part in common.

That is the blower motor. In this article, we will look at what the blower motor is and also why it might stop working.

Sometimes it may stop working just at certain speeds, but in this article, we are going to mainly focus on why the blower motor won’t work on any speed.

Read on to learn everything you need to know about your car’s blower motor, why it might stop working, and also some solutions on how to fix it.

Blower Motor Not Working On Any Speed

Blower motor not working on any speed?

What Is Blower Motor?

Before getting into details of why your blower motor might stop working it is a good idea to have a basic understanding of what your blower motor actually is.

Your car’s blower motor is the part that is responsible for pushing air through your vents. This can be cool air from the AC or warm air from the heater, but it is your blower motor that moves the air thru the vents.

The blower motor is basically a high powered fan that pushes the air thru the system.

Blower motors can come in two types. A three or four-speed system, and a variable speed system. On a three or four speed system, this means that the motor will run at three or four predetermined speeds.

On a variable speed system it the blower will constantly change the speed that it is blowing. It is important to know what kind of blower you have because certain problems only happen with certain blowers.

Normally though variable speed blowers are on vehicles with automatic climate control where three or four-speed motors are on everything else.

Now that you know what the blower motor is we can start going into why it might not be working on any speed.

Reasons Blower Motor Not Working

There are a few reasons why your blower motor may stop working. We are going to list them out here and if you want to jump to a specific section you can, but the main reasons a blower motor will stop working on any speed is:

  • A Bad Fuse
  • A Bad Ground Connection
  • A Bad Speed Control Module
  • A Failed Motor

1/ A Bad Fuse

The most common reason why your blower motor won’t work on any speed is that you have a bad or blown a fuse

The most common reason why your blower motor won’t work on any speed is that you have a bad or blown a fuse

The most common reason why your blower motor won’t work on any speed is that you have a bad or blown a fuse. A fuse is a small wire inside of a connector that is used to protect the motor itself from a surge of electricity.

It is better for the fuse to blow if it gets too much of a current than for your whole blower motor to get fried. Most cars have the fuse in a fuse box under the hood or in a fuse panel under the dash.

You can locate the fuse to your blower motor. If it is blown, then all you have to do is replace it, and that should fix the motor.

You want to make sure to check the blower motor fuse and also the HVAC controller fuse because either one of these being blown can cause the blower motor to stop working. If it is not blown, then you will have to look farther into the issue.

Another thing that is tied to bad fuses is bad relays. The relays are basically larger fuses. Normally though they are not the issue if the blower motor won’t work on any speed though because there is a relay for high speed and low speed if it is something to keep in mind and check because it is possible that both could go bad at the same time.

This is especially true if they somehow got melted from getting too hot. It doesn’t take long to test relays, so while checking the fuses, you might as well check the high and low-speed relays to make sure they are working right.

2/ Bad Ground Connection

The next reason that your blower motor may not be working is that it might have a bad ground connection.

To test this, you can run a fused jumper from a battery to the power side of the motor and attach a temporary grounding jumper to the other motor terminal.

This will provide grounding for the motor, and it should run at high speed. If it does, then you know that the issue is that the motor is not being grounded. When testing your battery, if the battery has low charge, you can recharge it by using best battery maintainer, the tender will keep your battery fully charged and by the way, it will also minimize the risks of long-term damage to the battery due to either under-charging or over-charging

The way to fix this is to locate the grounding point for the motor and clean it. After a good cleaning and making sure the motor is connected to the grounding point try to power the motor using the car and see if it works. If it does, then your probably is solved.

Another way you can test to see if it is a bad ground connection is to disconnect the electrical connector at the blower motor and then attach a multimeter to the motor.

Then turn your key to the run position and see how much voltage you are getting. It should be 12+ volts. If you have a reading, then connect one lead to the power terminal on the motor and the other to the ground.

This will let you know if the ground is good. If it is, then you most likely have a dead motor, but if it isn’t, then that is a sign that the motor is not being grounded and you can clean it like previously mentioned.

This should fix the problem, but if it doesn’t, then you might have to try cleaning the grounding connection more, but first, you should check the speed control module.

3/ Bad Speed Control Module

The speed control module is responsible for controlling the speed of the motor. This is true for variable speed motors. If the speed control module goes out, then the motor will not run.

To test the control module, you can disconnect the electrical connector at the blower motor. Also, disconnect the jumper power and ground connections.

You want to bypass the speed control. Then run a fused jumper from a battery to the power side of the motor and connect a temporary grounding jumper to the other motor terminal.

The motor should run at full speed. If it doesn’t then the issue is something else. If it does run at full speed though, then you know that the issue lies in the blower motor speed controller or the HVAC control head, but you will have to use a scan tool to see which one of those is the problem and then have it replaced.

4/ Bad Motor

sometimes blower motors do go out

Sometimes blower motors do go out

If none of these past things seem to be the problem, then the last bit is that you have a bad motor.

It is actually pretty uncommon for the motor to go out itself before something else and you normally have a warning when it is about to fail because it will start running poorly and squeak or slow down and things, but sometimes blower motors do go out.

If you can’t get the motor to run with these troubleshooting tips, then you will need to replace the motor because it is most likely dead, but do these other things first.

Circuitry

Knowing the circuitry of your motor is important because you will need to know that to find where the ground is and different things.

If you don’t know the circuitry of your motor or the type of motor you have, then you can look it up and find specific information for your vehicle. This is also important for locating fuses and relays.

Conclusion

Now you know the possible reasons why your blower motor won’t work on any speed. You know that the most common issue is a blown a fuse, but also sometimes the speed control module can go out if you have a variable speed motor.

You know how to check these things now though and also how to fix them. You also know that both variable speed motors and three or four-speed motors can suffer from bad grounding.

After reading this, you can test for that issue too and fix it.

Lastly, you know if all else fails, then the motor is probably bad and needs to be replaced. You know that the blower motor is the key part in moving the air in your AC and heat system and that you should replace a blower motor that isn’t working on any speed right away so you can stay cool in the summer and warm in the winter while driving.

How To Replace ECM Computer?

Have you ever wondered how all the parts in your car always seem to work in the correct way that they need too? Well, you don’t have to worry anymore.

In this article, we will talk about the part that controls all the other parts of your vehicle, and that is the ECM computer or Electronic Control Module.

In this article, we are going to talk about how you replace one if it does stop working and signs to look out for to know if your ECM has gone bad. Read on to learn all you need to know about the ECM and how to replace it.

How to replace Ecm computer?

How to replace Ecm computer?

What is the ECM?

Before going into detail about how to replace the electronic control module, we will first briefly talk about what it is. The ECM is basically the brain of your computer.

It is responsible for taking all the information from the different sensors, processing that information, and then sending more information back out to the car so it runs right.

The ECM tells the engine how much gas to inject into the cylinder when to shift the transmission, and many other things. That is why it is critical to have a properly working one.

How to Know if Bad?

Most of the time the ECM will last the life of your car, but sometimes people do have them go bad before the car is done for.

Depending on the make and model of the car you can look up and see if it is a common issue for the ECM to go out because some vehicles are prone to this issue more than others.

If your car starts running sporadically though or if it stops running completely, then it might be the ECM that is bad. For cars that start running funny though you should check that all the other sensors are good first.

If you get a check engine light, then see the code because chance is it is not the ECM if the check engine light is on.

If the ECM does go out, you normally don’t have much warning because it is the part that is responsible for giving you warnings when things go wrong, so if you have checked everything or if your car just isn’t able to start one day, then you should have your ECM checked out.

Replacing your ECM

Once you know, it is the ECM that is bad you have the choice to either try to repair it or replace it.

Most of the time it is a bigger hassle than it is worth to try to repair it because you have to open it up and the repairs can be complicated with all the electrical parts on the inside.

Repairing an ECM is like repairing a computer’s motherboard, so unless you know what you are doing or have someone that knows what they are doing and doesn’t charge a lot, you are better off with just replacing a bad ECM.

Another reason why it is normally better to just replace the electronic control module is that it is normally a pretty easy task. It really is only a few steps.

The main steps are locating the old one, disconnect it, and then plugging the new one it. It really is that simple, but we are going to go into more detail on each one shortly and the other minor steps you need to take before changing out your ECM.

Finding the ECM

Before finding where the ECM is in your car, it is normally a good idea to go ahead and pop the hood and disconnect the battery first.

It is important that you do this, so you don’t damage anything else when replacing your electronic control module, that is why it is recommended to just do it as the first thing, so you don’t forget to do it.

Once you have the battery disconnected, you can find the ECM. In most vehicles, the ECM is a silver box looking thing. You can look up your car and find what it looks like, or if you already have the replacement, then you know what it looks like because it will look like that. When checking your battery, i highly recommend you use top rated battery maintainer to recharge your. Battery need to maintain after long time running.

As for what part of the car your ECM is in can vary. Some cars have it under the hood in the engine bay area while other cars have it mounted under one of the seats in the cabin.

Some manufacturers even stick it up inside the car behind the panels on the inside. There are also a handful of other sensors that can look very similar to the ECM, so it is important that you are removing the right one.

If you don’t know where your particular vehicles ECM is, then the best thing you can do is look it up online or find a manual for your car. This way you don’t have to spend a bunch of time looking for it and can just get straight to finding it.

Removing it

Once you find it the next step is to remove it. For most vehicles, this just means unplugging the cords and unbolting the ECM because in most cars it is bolted down to keep it from moving.

To unbolt it you will have to get a proper size socket wrench and remove the bolts before you can remove the ECM completely. Normally it is best to unplug the wires and then unbolt is, so the wires don’t get damaged if the ECM moves while loosening.

Sometimes the wires will also be bolted on, and if that is the case, you will need the proper size socket to remove them from the ECM.

It is important to be careful when removing the electronic computer module because you don’t want to damage any connectors, and wires or damage the bolts.

Install new one

Once the old one is removed, you just have to hook the new one into the spot where the old one was. It is best to bolt the new one down first and tighten it into place. Then after it is in the proper position you can plug the wires into it.

This is again to help prevent damage to the wires. Once the new ECM is in you can put back any panels that you had to remove and then reconnect the battery.

If the ECM was the issue, then your car should start running properly again. Sometimes you will need to let the car run for five minutes or so, so the new ECM can run all the required checks on the system.

Calibration

However, if the vehicle does not start running right, then the ECM might need to be calibrated. Sometimes you can buy them already calibrated, but sometimes you have to do this yourself.

It can be complicated calibrating the ECM, so if yours needs to be calibrated, then you might have to take your car to the manufacturer to have them make the adjustments needed to get your car running right.

Conclusion

Now you know how to change your electronic computer module. You know that it is pretty much as simple as locating the old one, disconnecting it, and then connecting the new one assuming it is already calibrated right.

You also know what the ECM actually does now and signs of a bad one, so the next time you have ECM problems you are prepared to take care of it and possibly replace the ECM on your own.

What Causes Transmission Slip When Cold?

Your car’s transmission is a key component. It is the part of the vehicle that is activated when you do what most people call to put the car into gear. This is when you take it from park and put it into reverse or drive.

Then, as you are driving the transmission switches in different size gears into the drivetrain to get the most efficient power from the engine to the wheels.

Sometimes though when you put your car into gear or when it tries to shift gears it will shift hard or not correctly. This is what most people call slipping.

In this article, we will look at signs of a slipping transmission and also talk about why it may be happening when it is cold outside. Read on to learn everything you need to know about the reasons a transmission might be slipping when it is cold.

What Causes Transmission Slip When Cold?

What causes transmission slip when cold?

How to Tell Transmission is Slipping?

For some people, their transmission works fine unless it is cold. We will cover why this might be short, but before that, we will talk about the signs of a slipping transmission.

Knowing the signs of a slipping transmission is important because if you catch the problem early enough, then you can fix it before major damage occurs.

The first sign of a slipping transmission is hesitation when you put it into gear. What is meant by this is when you put the car from park or neutral into drive or reverse it takes longer than a second.

This delay is a sign that there is an issue with the transmission. When changing gears, the transmission should switch pretty much instantly as you move the gear shift.

The next this is if there is a clunk or jolt when changing gears. This means there is an issue with the gearbox and needs to be looked at right away. This is also the case if you notice hard shifting while driving and the car is switching gears.

The next sign is high RPM (Rotation per Minute) of the engine before the car shifts. If your vehicle gets much above 3500 RPM before shifting, then that is a sign for concern, especially if it happens regularly.

This lack of shifting quickly enough can also cause delays with your acceleration. This is a bigger issue than you might think because it can put you in harm’s way while driving.

How to tell transmission is slipping?

How to tell transmission is slipping?

Also, high RPMs may occur when the car downshifts if you have transmission issues because it might downshift sooner than it should.

Lastly, if you notice any odd smells while driving such as burning oil and it is accompanied with the hard shifting, clunks, grinding, or more noise while driving, then this is a major indication that the transmission has an issue.

One last thing to pay attention for is a check engine light because most vehicles will put off codes if the transmission starts to go bad.

Issues When Cold

Some of you though may only have these mentioned issues when it is cold out. This is the point where we will start covering why that is.

The main reason why that might be is that you have low transmission fluid. Like the engine and its oil, the transmission has fluid that helps keep it lubricated.

If the fluid is low, then it may not move thru the transmission fast enough when it is cold out to do its job properly.

This is because the fluid gets less viscous or thicker when it is cold and if it is too thick, then it can’t move thru the transmission lubricating it and reduce hard shifting or slipping.

That is why if you experience any of the mentioned signs, especially if it is only when it is cold out, that you check the transmission fluid level and make sure you have enough transmission fluid in the system.

The next thing that can cause slipping, especially when it is cold out is that the transmission fluid is old and deteriorated. As you drive and the fluid circulates thru the transmission, it gets hot, and when it gets hot, it starts to break down.

Over time this breaking down will eventually cause the fluid not to work right. It might make it get thicker than normal, especially when cold, or it might make it too thin.

Old fluid can also end up burnt. So, if you have enough fluid when you check the fluid levels if you are noticing problems, then the next thing to do is look at the quality of the fluid.

If it looks old and burnt, then you might need to replace it. You can also buy a kit to test the fluid quality, and this will let you know for sure if the fluid needs replaced or not.

The next reason that can cause slipping, especially when it is cold out is that the transmission fluid is old and deteriorated

The next reason that can cause slipping, especially when it is cold out is that the transmission fluid is old and deteriorated

But old transmission fluid that is worn out can cause the transmission to slip, and it might be more noticeable when it is cold because the cold is affecting the broke down fluid more than heat does.

The last thing that can cause your transmission to slip when it is cold is old or dirty oil. Oil also runs thru the transmission and like the transmission fluid if it is old and it is cold outside, then it might be getting too thick to move correctly thru the system.

That means if you have checked your transmission fluid level and the age of the transmission fluid and know that it is good, but you are still having issues of a slipping transmission when it is cold out, then you should check the oil next.

If you have old, burnt, or dirty oil, then you should have it changed or change it yourself, and this will not only help your transmission shift better but will also extend the life of your engine and help it run better.

Oil should be changed fairly regularly at scheduled intervals that depend on the vehicle, but it is important to stay on top of changing your oil to make sure everything in your car will run smoothly.

Conclusion

So, now you know why your vehicle’s transmission might slip only when it is cold outside. You know that the transmission fluid level might be low or the transmission fluid might be old.

You also know that if the transmission fluid isn’t the issue, then it might be your vehicle’s oil. Outside of the reasons why you also know the signs of a slipping transmission.

It is important to pay attention to these things and get your transmission looked at before things become worse. This is especially true if you start noticing the issues all the time and not just when it is cold.

That is because if it starts happening even when warm, then the transmission may have bigger issues, than just not enough or bad fluid. Now you know all you need to know about transmission slipping when it is cold outside.

Can A Car Run Without A Battery?

Your car’s battery is a key component in it. A lot of people have experienced a dead battery and the issues that have caused you. Your car uses the battery to send power to the spark plugs to get the engine to turn over.

This means that if you have a weak battery, your car won’t even start. However, some people still wonder if you can run a car without your battery?

Well, read on to find the answer to this question and also all the important details pertaining to this question. The answer may actually surprise you.

Can A car run without a battery?

Can A car run without a battery?

Cars Electrical System

So, before getting into the answer of if you can run your car without the battery or not, we will first take a brief look at the electrical system to help understand this question.

The electrical system is composed of your car’s battery, the alternator, and all the other electrical components. The battery is normally used to run anything needed power, and the alternator takes extra mechanical power from the engine and uses it to recharge the battery.

This process continues while the car is running and then when you turn it off you should have a charged battery that is ready to start your car again.

Can you run car without battery?

So based off of this explanation it would sound like you can not run your car without the battery because the battery is what supplies the power to everything that needs it.

Well, this assumption that you can’t run your car without the battery is false. You actually can run a car without the battery, assuming that it is already started and running.

That is because the alternator can provide the power to the system if there is not a battery there to run them. Continue reading to learn how this works and why it works.

If you battery is dead, you should replace it, but it is not, you should use the best battery tender to recharge your car battery.

What about bad alternator? Will your car run with a bad alternator?

The answer is yes, but the car will be only running for a short time and the energy stored in the battery will also running strictly off

Alternator powering things

The alternator is generally strong enough to power the basic things because it normally puts off 14 volts of electricity. You may know that a car battery is normally only 12 volts.

The extra volts that the alternator puts off is so the battery can get fully charged while being drained, but if the battery isn’t there, then the alternator can send the power it is putting off to the electrical components that need them.

So, yes you can run a running car without the battery. It is just ran off the alternator if the battery is not present.

Should you

you should not run your car without a battery

You should not run your car without a battery

Just because you can do something though leads to the question of should you do it. In this instance should you ever run your car off the alternator and disconnect the battery while the car is running.

The answer to this is normally no; you should not run your car without a battery. This is for multiple reasons.

The main reason why you should not run your car without the battery is that the alternator doesn’t always put off even amounts of power.

This means that as the car runs the alternator can spike with the power output that it is putting out. Your battery can handle these spikes and has buffers designed to protect it, but other parts of your cars electrical system does not have protection against these spikes.

That means that parts of your electrical system could get fried or blow if you are running them off the alternator instead of the battery.

Outside of surges and possible damage to your car you should also not run the car without a battery because it puts extra stress on the alternator.

This is because the alternator is not designed to run parts of the vehicle but instead is intended to charge the battery. Whenever you use something for a purpose that it wasn’t made for you, risk damaging it.

There are very few reasons why it would be a good idea to disconnect the battery while the car is running even though you technically can, and the vehicle would stay running.

You may have disconnected your battery while the car was running before or had someone tell you it is okay, but it is not recommended.

You might do it a bunch, or they might have done it a bunch and had no bad luck with surges, but it only takes one time and one surge to ruin the whole electrical system of your car.

So it is important to remember the risk involved in running your car without the battery before doing it even though you can.

Start without Battery

So, this might lead you to the question of why can you not start the car without the battery? If the alternator can run the car and electrical components while the car is running, why can’t it put off power to start the car?

Well, the reason that the alternator can’t be used to start the car goes back to how it works and what it is made to do. It is made to convert mechanical power from the engine to electrical power.

The alternator just converts power and does not store power. That is why a car has a battery. The batteries job is to store power so the car can use it when it is not running and has no other source of power.

This is why if your battery is dead you can’t start your car and why also why you can’t start your car without your battery.

Conclusion

So, now you know that you actually can run your car without the battery. This might be a surprise to some people since the battery is such an important part, but as long as the car is running the alternator can provide enough power to keep it running and power the different systems.

However, just because you can run your car without the battery doesn’t mean you should. You risk damage to your alternator and the rest of your car if there is a power surge.

That means you shouldn’t risk running your car without the battery unless you have a very good reason.

Also, it is important to remember your car won’t start without the battery, so if you are running it without the battery don’t expect to be able to start it again until you connect the battery.

Now you know all you need to know to answer the question of can you run your car without the battery?
