Car Still Won’t Start After Replacing Battery?

A dead or bad battery is a common reason why a car will not start. A car uses the power from the battery to engage the starter to get the car’s engine to turn over. This takes a lot of power, and a weak or bad battery is not capable of doing this.

A lot of times you can use another car and jump the battery to help get it going to get to a place to have the battery replaced, but what if your car still won’t start after having the battery replaced.

Well, to find the answer to this question keep reading and we will go in-depth to the different reason why the car still might not be starting and some solutions for them.

Diagnostic

A lot of times to figure out what is wrong with a car that won’t start, a lot depends on the sound that the car makes while you try to start it. If it makes a K-K-K-K type sound, then chance are the battery is bad or not connected right.

The first thing to check after replacing a battery and the car still not starting is the battery wires. It is more common then you may think that the battery did not get connected right.

The leads could have come loose or not be making good contact. Check them again after replacing the battery and see if they are in fact tightly connected.

The next thing could be that you replaced it with the wrong type of battery or a battery that is not strong enough. If the new battery doesn’t have enough cold cranking amps, then this can prevent it from starting the car.

Recheck the new battery and make sure that it is at least equal in strength to the old battery that you had. If it is, then you can move on to the next stage.

Alternator

The other thing that could lead to the K-K-K-K sound is a dead battery. The battery may be new, but if you have been driving the car, then it might have got drained, and if the alternator is bad, then it won’t have been getting recharged.

The alternator not working normally triggers lights on your dash, so if you see lights come on, especially the battery one look in the manual and see what they mean.

If you have an alternator that is failing, then it doesn’t matter how new the battery is because it won’t be getting charged as you drive and therefore won’t be able to start the car.

Starter

If the sound you get is a Grr-Grr-Grr type noise, then chance are it is not the battery that is the problem causer at all. A growling Grr sound when trying to start the car is an indication that the starter is bad.

If the start is bad, then it will need to be replaced. There are also a few other sounds that come with a bad starter.

The first is no sound at all. If when you turn the key, no sound is made, then it might be a bad starter, but could be a few other things that we will get to later. If you have no sound though, then you can have the starter tested to see if it is bad.

Lastly, if you hear a grinding, clashing, or banging sound while trying to start the car, then it could be an indicator that some of the teeth on the starter are broke. A

sound that sounds like shifting with a bad clutch could mean that the starters drive gear might be damaged, or the flywheel on the vehicle may have damaged teeth.

If you have any clashing, knocking, or metal scraping sounds when trying to start the car, then you need to have it checked out to make sure more damage does not occur.

Reasons why cars can not start

There are many reasons why cars can not start

Fuel Pump

Another problem when the vehicle doesn’t make a sound when you try to start it could be a bad fuel pump or fuel pump relay. When you turn the key to the on position, you should be able to hear a soft whine of the fuel pump intake turning on.

If you don’t, then the fuel pump motor might be weak or dead. If the fuel pump is just weak, you might be able to tape on the fuel tank near where the pump is at to get the motor going, but this won’t always work if it is to die.

A dead fuel pump will need to be replaced but check the relay first to make sure it wasn’t just a blown a fuse.

Also, make sure you have enough gas in the car for it to be able to start. Sometimes you don’t have enough gas for the fuel pump to suck it up. This can especially happen when parked on an upward slope.

The gas might be in the back of the tank and not going into the fuel pump. One last problem that the fuel system might be having that prevents the car from starting is frozen lines.

If it is cold and water got into the gas system, then the lines can freeze, and this can prevent the fuel from getting to the engine and being able to start.

Bad Spark Plugs

Talking about the fuel, the problem could also be that it isn’t igniting properly. If you have old spark plugs, then they may not be firing a good enough spark to get the engine to turn over.

Spark plugs usually last for 100,000 miles, so it can be easy to forget to replace them. Check them if the engine is not turning over and making a misfiring type sound.

Also, bad spark plugs will cause the engine not to run smoothly, so before you get to the point where the car won’t start, if you notice rough idling or riding, then check the spark plugs and make sure they are still good.

Security System

The last possibility of why a car with a new battery might not start is that the security system got engaged. If the steering wheel will not turn, then the anti-theft system got tripped.

To get the wheel to unlock you need to nudge it some. This will help loosen it from the locking pawl and will allow the car to start.

Another security feature that may keep your car from starting is if it has a proximity key. Make sure the key is in the car or on your person or else the car won’t start. If you are rushed, then you might have forgotten it in the house or left it in your pants or jacket from the night before.

Before freaking out, make sure you have it on you because the problem might be as simple as just not having the proximity key in the car with you.

Conclusion

 

There is a lot of reason why car still won’t start after replacing battery. The critical thing is to stay calm and work your way thru the problem.

First, make sure the new battery is connected right and is the right one. Then, if your car has a proximity key, make sure it is with you. Next, listen to the sound the car makes when you try to start it.

If it is a K-K-K-K sound, then the battery is weak or not connected. If it is a Grr sound, then it is most likely a bad starter. Clashing sounds can also be the starter or flywheel.

If no sounds happen, then it could be the starter or the fuel pump not working. Depending on the sounds you get, you can have an idea of where to start for checking things so you can get your car running again quickly and without spending too much more money.

What Voltage To Charge An AGM Battery?

Over time and use batteries go dead and then they need to be charged. The longer a battery sits without being used, the more it will drain. This is especially true in extreme temperature areas.

Even AGM batteries, which are top quality, will need to be charged at some point. When it comes time to charge an AGM battery, what voltage should you use?

Well, after reading this you will know and then be able to choose the right charger for your battery and charging situation.

What voltage to charge an AGM battery

What voltage to charge an AGM battery?

AGM Battery Overview

Before getting into voltage we will give a fast break down of what happens in the battery when it needs to be charged. In an AGM battery, you have absorbed glass matts, and they hold the electrolyte mixture that holds the charge.

You also have metal plates. As time passes the sulfur in the electrolyte sticks and builds up onto these metal plates. When this happens, the electrons are trapped and can’t move thru the battery. That is why it has a low charge.

What A Charger Does?

A charger sends pulses into the battery, and these pulses help break the sulfur build up off the plates. The sulfur is restored into the electrolyte which is held on the glass matts in an AGM battery, and this restores the charge to the battery.

As the battery ages though some of the sulfur is lost or stuck permanently to the matts and this is why batteries eventually go bad.

What Voltage To Use?

So, now that you understand the basics of how charging works, what voltage should you use? Well, picking the right voltage is pretty easy.

Voltage is the amount of energy that is going into the battery, and you want the voltage to be equal to the voltage of the battery when choosing a charger.

This means if you have a 12-volt battery, then you would want to get a best 12v battery charger. It is that simple when it comes to the voltage of making sure that the voltage matches the voltage of the battery.

Some chargers have switches, and you can change the voltage that is being put of by the charger. These are nice, especially if you have multiple batteries of different voltages around.

That way you can use the same charger for all your batteries. Just make sure you change it to the right voltage setting when switching your batteries out.

If you have a 12-volt battery, then you would want to get a 12-volt charger

 

What Amps?

If figuring out the voltage to use is as simple as matching it to the voltage of the battery, then what makes charging an AGM battery different from others? Well, we have an article available for you about that, but the key part is to use lower Amps with an AGM battery.

For the full explanation of why you can read the other article, but amps is the speed at which the current is being applied to the battery.

To prevent heat and to overcharge it is better to apply the charge slower with AGM batteries. This has to do with how they are made.

In the other article, we also cover if it is necessary to use an AGM charger or if a standard battery charger will work with AGM batteries.

How Often To Charge.

AGM batteries don’t need to be charged as much as other batteries, but they do still need to be charged. You should test them, and once they start getting down to 10,5 volts or so, you should load them.

You should keep your battery on a maintainer when it is not being used for long periods and this will help it not lose its charge and will help the battery last longer.

Conclusion

AGM batteries do still need to be charged like other batteries, but they hold their charge better so don’t need to be charged as often. When loading an AGM battery, it is important to remember to use a charger with lower amps.

For the voltage of the charger to use it is simple to figure out. When charging any better, you want to make sure the energy of the charger matches the voltage of the battery.

That is not just true for AGM batteries but is a rule for all batteries. The voltage is how much power is being put out, and amps are the speed at which it is being put out.

To charge a battery properly, the voltage needs to be the same as the battery being charged. If it is less than the battery being charged, then it won’t charge all the way, and if it is more, then it will damage the battery.

It is that simple to make sure the two voltages match when determining what voltage to charge your AGM battery at.

Agm vs Standard Battery Charging: Do You Have To Use AGM Charger On AGM Battery?

There are a variety of types of lead acid batteries on the market and each one works slightly differently. They all do the same thing, and that is provide power to something, and they all do it in roughly the same way with plates and electrolyte in between, but they hold the electrolyte in different ways and can run out of juice in different ways.

This means that they need charged in different ways. After reading this, you will understand the difference in charging an AGM battery verses charging a standard battery, and the best charger for each one.

Agm vs Standard Battery Charging

Do you have to use AGM charger on AGM battery?

What Does Charging Do?

First though before getting into the specifics of different types of chargers and which to use with what kind of battery we will cover what charging actually does. In a battery you have the electrolyte which is a liquid that holds the electrons.

The electrolyte is a mixture of sulfur and some other parts. Over time, the sulfur and the electrons with it stick to the metal plates inside the battery and builds up. When the electrons are stuck to the plates, instead of being able to flow thru the battery, that is when the battery is considered low on charge.

By charging the battery a pulse is sent into the battery and it breaks the sulfur build up off the plates. This frees the electrons and puts them back into the electrolyte where they are able to move thru the battery again and provide juice to whatever the battery is connected too.

Standard Battery

In a standard battery the electrons are housed in just the liquid mixture and a part of that mixture is water. When you recharge a standard battery, the charger normally puts off a strong pulse and charges quickly.

This is because standard batteries with liquid in them are not hurt by being charged fast. By charging the battery fast you can start using it again quicker.

The problem with charging a battery fast though is that it causes a lose of the water inside of the mixture. It evaporates off and heat is formed. A standard battery though the heat goes away with the water that is being lost and normally it doesn’t get hot enough for damage to occur.

Charging a battery fast though can also lead to over charging. This is when pulses are still being sent in, but there is no more sulfur to be broke off.

Over charging of a standard battery again does not cause much damage and just causes water to be lost. The reason this water lose isn’t a big deal though, is that water can be added back into a standard battery making it so it will function the same.

AGM Battery

AGM battery

An AGM battery

An AGM battery on the other hand though, you can not add water back to it. This means that water that is lost has to get back in a different way. For an AGM battery there is a catalyst such as platinum, that is able to turn the hydrogen atoms that are created when charging back into the water.

In an AGM battery there are glass matts that absorb the liquid and AGM stands for Absorbed glass matts. These matts suspend the electrolyte and makes it so the battery does not leak.

Since water can not be added directly back to an AGM battery though, then once the catalyst is gone inside, it is gone, so you should do everything to prevent the need for it.

When it comes to charging, that means you should charge an AGM battery low and slow. This is because if you add a low amount of pulse over a longer period of time not as much heat will be made, so the battery won’t get as hot.

Also, if you charge it slowly, then you are less likely to over charge the battery and cause damage. However, you don’t want to under charge the battery either. That is why they make chargers designed for AGM batteries and are labeled as that.

A charger labeled for use with AGM batteries is normally more of a battery tender. This means that it has computers that can monitor the level of charge in the battery. As it gets closed to being fully charged, then the charge can slow down, so as not to over charge the battery.

These special chargers will normally stop charging once the battery is fully charged, and won’t start recharging again till needed, meaning they can be left connected.

Do You Have To Use AGM Charger On AGM Battery?

So, now that you understand the difference between a standard charger and an AGM charger, a lot of people will ask if you have to use an AGM charger for an AGM battery. The technical answer is no you don’t have too.

The standard charger will charge the battery and if monitored will not cause harm to the AGM battery, especially if used on the lowest setting, but if you are not careful, then it will over charge the battery and lead to the AGM batteries life being cut short.

That is why even though you technically don’t have to have an AGM charger for an AGM battery, it is a good idea to have one. You spent good money on an AGM battery, so make sure you charge it properly and don’t damage it and get a charger designed for it.

AGM battery charger

Though you technically don’t have to have an AGM charger for an AGM battery, it is a good idea to have one

Conclusion

AGM and standard batteries both charge in the same way. The charger applies a pulse to the battery and this breaks the sulfur off the plates and restores it to the electrolyte allowing the electrons to flow freely.

The difference is when you charge a battery it loses water, and this is especially true with strong standard chargers or if you over charge a battery. With a standard battery this isn’t much of an issue because you can add water back, but with an AGM battery you can’t add water back.

It has a catalyst inside the turn the hydrogen back into water, but once the catalyst is gone, the batteries life will be almost over with. That is why you should use an AGM battery charger on an AGM battery to keep the life of the battery up and prevent water lose and over charging.

How To Find Ground Fault With A Multimeter?

Multimeters can be used for all kinds of purposes. One of those is locating a ground fault in a circuit. After reading this article you will know what a ground fault is, why it is bad, and how to use a multimeter to find one.

We will go thru the steps required to safely find a ground fault so it can be fixed and not cause harm.

How To Find Ground Fault With A Multimeter

How to find ground fault with a multimeter?

Ground Fault

Before going into how to find a ground fault with a multimeter though, it is a good idea to know what a ground fault is.

A ground fault is when wiring is worn, chafed, pinched, or bad and current is getting out of the system and into the ground.

Normally current either gets to the ground thru the circuit and a dedicated wire or the current doesn’t go into the ground at all, but instead stays in the circuit.

Dangers of Ground Fault

The reason why ground faults are dangerous is that if current is getting out it means something is damaged in the system. The thing might still function properly, or it could not have enough power going thru the circuit and the item might not function right.

Ground faults are also dangerous because if you are working on the item that has a fault and touch the part where the fault is, then the current can go thru you.

This will only happen if the thing is on though, so if working on something make sure it is off. You may touch the bad wire though unknowingly with normal use and get shocked. Even worse, depending on what the bad wire touches it could cause a fire or worse shock.

If the wire with the ground fault touches water, then it can shock everything in the water. This is why you need to find ground faults as soon as possible, if you suspect one.

Using Multimeter To Find Ground Fault

Using Multimeter To Find Ground Fault

Using multimeter to find ground fault

One of the easiest ways to find a ground fault is by using a multimeter. This is good because a lot of people already have multimeters on hand. Continue reading this and you will learn the steps required to safely find a ground fault.

Any multimeter will work for finding a ground fault. You don’t need the most expensive one on the market and there are a lot of different ones on the market.

All you need is a multimeter that is reliable. Make sure the object that you are going to be testing is unplugged and off. Then also make sure that the probes are connected to the multimeter.

Once his is done set the multimeter to the ohm setting. If your multimeter has more than one position for the ohm setting, then set it to the 1x position.

After you have the multimeter on and set up, it is time to do the ground fault test. Touch one probe to a terminal and touch the other to the device housing or mounting bracket.

Now, you move the first prob that is touching a terminal to another terminal. If the multimeter reads anything besides infinity during any part of the test, then there is a ground fault.

If you are testing something with multiple circuits, then you can use the multimeter to determine which circuit is bad as well.

If for example you have a battery that is connected to a fuse, then you can connect on probe to the battery side and then one to the fuse side. Start turning off fuses unitil the reading is correct or the infinity symbol and then you will know which fuse is bad. Talk about battery, if you need a tool to maintain your car battery, i recommend you using the best battery tender, i used it and it is great tool to do that.

The thing about finding ground faults in a circuit that can be annoying is figuring out which one it is, but it really isn’t that hard. You just have to test each on until you find the bad one.

This requires being patient and taking your time. If you stay patient and take your time though, then you can find which circuit is bad and know which one to repair, instead of having to fix them all.

Fixing Ground Fault

The best way to fix a ground fault is just to replace the bad wire. This is the simplistic type of ground fault to fix. If it is just one wire or a few wires that are bad or old, then you can remove them and put new ones in.

Sometimes though the ground fault is in a specific part. If that is the case, then you have to replace that whole part. It is normally not worth the trouble or safe to fix the part instead of replacing it.

Also, you should never use a part with a ground fault for the danger or damage that it can cause. Just order the new part and replace the whole thing, to fix the ground fault problem.

Conclusion

find ground fault

Ground faults tend to not be hard to fix, but they can be a real struggle finding sometimes especially depending on how big the system or circuit is.

The trick to finding the ground fault though, is breaking the system down into smaller sections where you can and using patients and going slow when you can’t break it down.

Then you just need a simple multimeter that is reliable to start testing. To test for a ground fault connect one probe to a terminal and the other to the case of the object and then move the first probe from terminal to terminal.

If the multimeter on the ohm setting gives any reading besides infinity, then there is a ground fault. If the system has breakers, then you can connect on probe to the terminal and the other to the breaker.

You can then shut the breakers off, until you find the one that is causing the bad reading. That way you know which part of the system you have to work on.

Once the ground fault is located, then it is easy to fix. You just have to replace the worn or pinched wires with new ones and the problem should be solved. Sometimes though it is a whole part that is bad and you will have to replace it. Grounds faults are dangerous though and should be taken serious. They should be found and repaired as soon as you are aware of one existing.

Car Battery Won’t Charge: Why And How To Solve?

Dead car batteries are an annoying thing. This is especially because a lot of times they happen out of the blue. Sometimes it is from something simple such as a light getting left on and you can jump the car and get on your way, but sometimes the battery is too dead to jump and needs completely charged.

What does it mean though if your car battery won’t charge. Well, in this article we will look at some of the possibilities of why a car battery won’t charge and some of the solutions for that.

car battery won't charge

Car battery won’t charge?

Bad Alternator

The first reason why a car battery might not be charging is that the alternator may be bad. The alternator is what converts the spinning of the engine into power that goes back into your battery.

Normally, when a car and alternator is working properly, the alternator will charge the battery as you drive, so then it will have enough power to start the car again the next time you need it too.

If the alternator is bad though, then it is not providing any charge to the battery and their for the battery is not charging.

The alternator not charging the battery could be something as simple as the connections have came undone. If that is the case, then all you have to do is reconnect things, and it should start working properly.

Vibration while driving or wires going bad is how the battery and the alternator could become disconnected. If they are not disconnected though, then their must be something else going on.

You can run a test on the alternator by a automotive multimeter and see if it is putting off a charge. If it is not putting off a charge, then it is bad and must be replaced.

 alternator going bad

If the alternator is going bad, then it may not be converting as much energy to the battery

Getting an alternator replaced isn’t that hard and if you are mechanically skilled then you can do it yourself. If you aren’t though, then any shop can do it for you. If the alternator is putting off a charge, but it isn’t constant, then you might just have a bad belt.

If your serpentine belt is loose, then it could be slipping and not allowing the alternator to work properly. If that is the case, then you will need that belt replaced. Again, this isn’t that hard of a task to have done and isn’t to costly of a repair.

Bad Battery

Another reason why the battery may not be charging is that the battery itself is bad. A lot of things can go wrong inside of the battery. The battery could short itself out or get internal damage from shocks or vibration.

To find out if the battery itself is bad you can run some test on it. If the battery itself is bad, then you will have to replace it and get a new battery. A bad battery can not be repaired.

Also, if the battery shows visual signs of being bad, then it is time to replace it. If it has corrosion or leaks, then it is defiantly time to get a new battery. If the connectors aren’t corroded to bad, then they might be able to be cleaned off and this might allow it to charge properly again.

Another reason why a battery might go bad is just its age. As a battery is used suffer builds up on the plates and forms a crust. When the battery is being charged it breaks this suffer off of the plates.

battery itself bad

If the battery itself is bad, then you will have to replace it and get a new battery

Over time though the sulfur will not come off the plates all the way and won’t go back into the solution. Also, the sulfur eats the plates and over time and recharging the plates just disappear. As the sulfur is broke off the plates int he recharging process, a part of the plate goes with it.

Think of a rusted panel and how it crumbles, well the plates int he battery work the same way. If your battery is old it won’t recharge or hold a charge and again will have to be replaced.

Bad Charger

Another final reason why a battery might not recharge is that the charger you are using may be bad, not be the right type, or not be connected right. Some batteries require special types of chargers to recharge them.

If you are using a charger and it doesn’t seem to be charging your battery, then make sure it is the right type for that battery.

Another reason why the charge may not be charging the battery is your may not have it connected right. To connect a charger to a battery you want to make sure the positive lead is connected to the positive connector on the battery.

If it is not it will not work and cause damage to the battery. You then connect the negative to the negative pole on the battery. Once connected make sure you plug the charger in and set it on the right amps or speed of charge to match the battery.

If these things don’t work, then the charger itself might be bad. Try a different charger and see if it works with the battery you are trying to charge. A battery charger could get a short in it just like a battery can or the inside components could go bad. If you want to buy a new battery charger, this is the best battery tender for you.

charger itself bad

If the charger itself is bad, you should get a new one

A battery charger has to convert the AC or DC current into current that the battery can use and this converter mechanism on the inside of the charger might go bad or stop working. This is especially the case if the charge is old, or if the charger has not been stored or used right in the past.

Conclusion

So as you now know there are a few reasons why a car battery might not be charging. The alternator inside the car could be bad or you could have a loose belt inside the car. The battery itself could be bad. The battery could have damage that you don’t see or it just might be old and wore out.

If it has been recharged a bunch, then it just might not be able to be recharged any more. Lastly, the charger could be bad if you are trying to use an external charger or it could be connected wrong. After you have made sure it is the right charger and is connected right, you might need to try a different charger to see if that fixes the problem.

Now you have a better understanding of why a car battery won’t charge and should be able to trouble shoot it for the situation that is at hand for you and your current situation.

How To Check Car Fuses With A Multimeter?

The electrical system in a car can be one of the most annoying systems to find the problem of something with.

Sometimes, however, the problems in the electrical system is something simple such as a bad battery or fuse. If it is a bad battery, try to use best battery tender to maintain it. It is a tool to recharge your battery.

In this article, we will teach you how to check a fuse to see if it is bad or not using a automotive multimeter.

This should be one of the first things you do if you are having issues with a specific area of your car because it is the easiest and a lot of times is the problem which will save you a headache if you just start there.

How To Check Car Fuses With A Multimeter

How to check car fuses with a multimeter?

What Is A Fuse

First, though before explaining how to test a fuse with a automotive multimeter we will cover what a fuse is. A fuse is simple a wire normally surrounded by some plastic that completes a circuit when plugged in. Most fusses have two prongs with a small wire running between them.

When the fuse is plugged into where it goes these prongs touch another piece of wire and complete the circuit. It is that simple. The thing is a fuse is designed to break through if something goes wrong. This is because when the fuse breaks or blows, it will protect the more expensive part of getting damaged.

A fuse blows when to much power runs thru it. This extra power causes the metal wire to burn up breaking the circuit. When the circuit breaks the extra power cannot get to the main part that can not handle the extra power. In cars, there are normally fuses in two spots. There is a fuse box under the hood with all kinds of fuses in it, and there is also sometimes some fuses under the dash on the passenger side.

Check car fuse

What is a fuse?

Knowing where your fuses are is important if you want to check them. Some of the fuses are a different color, and each color indicates how much power it can handle. The bigger fuses though are normally a dark gray though and not a color.

On the small fuses, you can normally see thru the colored plastic, and this allows you to see if it is blown or not without testing it. Also, blown fuses may have discoloration which is a sign that it is bad and needs to be replaced. The big fuses though you can not see the wire, however, so these you will have to test if you think something is wrong with it. Read on to learn how to do this.

How To Test Fuse

The first step before testing a fuse with a automotive multimeter is making sure that the car is off and the keys are not in the ignition. This will help keep you safe when pulling the fuse out and also protects the car. The next step is to locate the potential bad fuse. To do this, you go to the fuse box and look at the diagram or in the owners manual and find the one that corresponds to the system you are having trouble with.

For example, if your power door locks aren't working, then you will want to pull the fuse that goes with that. Then to pull the fuse, you do literally what it is called, and that is pulled straight up on the fuse. You want to make sure you pull straight up because you don't want the prongs getting bent or damaged as you pull the fuse out.

Test car fuse with multimeter

Test car fuse with multimeter

Once you got the fuse pulled you can visually inspect it. If it is a clear plastic you can try to see if the connection seems broken. If you can't see the wire through, then it is time to get the multimeter out. To use the multimeter you first have to turn it on and get the probes out. You then can set the multimeter to ohms.

This will measure the resistance of the fuse. You can then touch the probes together. This gives you a baseline reading and will tell you roughly the number you will get once you put the probes on the fuse. Once you have an idea of the reading, you should expect you can connect the probes to the fuse.

To do this, you just have to touch one probe to one prong and the other to the other prong. This will give you a reading. If the reading is close to what it was when the two probes touched, then the fuse is fine. If it does not give a reading, then that means the fuse is blown. This is because the current it is trying to send thru the fuse is not making it back thru.

To make sure the fuse is blown you can change the multimeter set to the setting to measure the current which is the arrow with a line. You can then touch the probes to the prongs on the fuse in the same way. If it beeps continuously, then the fuse is fine, but if it does not emit a sound, then the fuse is blown. Either test is a sufficient way to see if a fuse is blown.

What To Do

Replace car fuse

Replace car fuse

If the fuse is blown, then it is pretty simple to replace it. You just have to buy another fuse that is the same and plug it in (click here to check price at amazon). If the fuse is not blown, then you will have to dig deeper into your electrical problems which can be frustrating. That is why it is good to start with testing the fuse first because for most people it will only take a couple of minutes to test the fuse.

Another thing to remember if it isn't the first fuse that you test is to make sure to look at the diagram closely and that you test all the fuses that go to a particular system. Sometimes a system may have more than one fuse, so you need to make sure you test them all with the multimeter to rule out one being blown.

Conclusion

So now you know how to test a car fuse with a automotive multimeter. It is an easy task, and pretty much any multimeter can do it successfully. You can either use the resistance or ohm feature on your multimeter to check the fuse, or you can use the continuity setting to test the flow of current.

Either one will work and will give you a reliable reading on if the fuse is blown or not. Also, don't forget you can visually check the fuse to which might be able to save you more time in finding out if your car fuse is blown or not.

How To Start A Car With A Dead Battery? (2 Ways)

Having a dead car battery can be one of the most frustrating things. You go out to your car in the morning or after work, put the key in and turn it and nothing happens or only a clanking sound happens.

This means you are probably going to be late to your next location because you got to figure out how to get your car started. Well, the good thing is a dead battery is something that can be fixed from right where you are at.

There is actually a couple ways to start a car with a dead battery. After reading this article you will know your options and how to start a car with a dead battery.

Options for Dead Battery

You have a couple main options if your car battery is dead and you need to get it started.

The first option is to charge the battery on a charger or a battery tender. For most people this isn’t a practical solution because when they find out their battery is dead it is because they are trying to go somewhere.

Also, not a lot of people have car battery chargers in there home. That means most people will use the other option and that is to jump the car. We will go into farther detail on how to jump a car below.

If you have a manual car, then you actually have a second option that people with automatic cars don’t have. If you have a manual car, then you can sometimes push start it depending on how low the battery is.

To do this though you need at least two people. The simple explanation of push starting a car is one person pushes the car, while the other person turns the key.

By pushing the car it causes the alternator to work and put off a charge to the battery. If the battery is not too low, this charge will be enough to give the battery enough juice to start the car.

How to Jump a Car With A Dead Battery

For those with automatic cars though you can’t push start them. This is because you can’t put the car in gear when it is off. That means you will have to jump the car.

To jump a car you will need jumper cables and another car. It really is that simple of only needing two components. That is why it is a good idea to carry a pair of jumper cables in your trunk for emergencies.

They do not cost much and you never know when you might need them. Now though we will go into how to use the jumper cables, so you can know what to do if you ever need to jump your car.

The jumper cables have two colored clips on them. One is normally red and the other is black. The red is positive and the black is negative. To jump a car you need to pop both cars hoods and open them.

This is so you can get to the battery. All you do is hook the alligator clips onto the metal terminals on each battery. Some cars have rubber caps over the terminals that you have to pop off.

Be sure to put the red positive clip on the terminal that is positive. To know which is which the positive will be marked with a plus sign. The black ground one goes on the other one that is marked with a minus sign.

On some vehicles the battery is positioned where you may not be able to get to the negative or ground terminal. If that is the case then there is most likely a piece of metal running along the battery that is connected to the ground part that you can hook the negative end too.

If you can not find such a piece, then you can just hook the negative end to any other piece of metal, such as the frame or side panel of the car.

The ground side just has to be connected to something metal to complete the circuit. The positive side is the only one that has to be connected to the battery.

Once you have the connectors hooked to both car batteries it is time to jump start the car. First you want to start the working car. Then, let the working car run for a minute or so.

This will allow the energy to transmit to the dead car. Once that is done you can try to start the dead car. If it doesn’t start wait a little longer and try again. Most of the time this works without any problems.

Once the dead car is running and can turn off the working car and carefully remove the jumper cables. You don’t want to touch the metal ends of the jumper cables whenever they are connected to either car.

Also, if you have gloves, then it is a good idea to wear them to protect you.

After the cables are removed, then you can close up the hood. It is a good idea to drive the jumped car a bit before turning it off to make sure that the battery will stay charged enough to restart it after turning it off.

If you don’t let the jumped car run long enough, then you will have to jump it again.

What if no other car

How do you jump a car if you don’t have another car around though? Maybe you are home alone and don’t want to call someone to come.

Well, if you have a lawn mower, then it most likely has a 12 volt battery too (if you want to be sure it has how many volts battery, you can use the car battery tester to test), so you can use it to jump start your car. You do that in the same way as if you were using another car.

What if no other car

What if no other car

This is a useful thing to know in a pinch, but to prevent this from happening you can also by a portable battery pack.

They make jump start kits that you can carry in your trunk that has a battery and jumper cables connected to it. All you do is connect the cables and turn the device on.

Then you just start your car like normal. It is highly recommended that everyone has one of these that they carry with them. The key though is to make sure it is always charged and taken care of.

You may forget you have it in your trunk and then when you need it, it might not be working right. They normally aren’t to expensive and it is nice to have the peace of mind that you can start your car no matter where you are at.

Also, they are cheaper then a tow bill if you do get stranded somewhere.

Conclusion

Enjoy your trip!!!

Enjoy your trip!!!

So, if you end up with a dead car battery you have a few options. You can remove the battery and charge it, push start the car if it is a manual, or jump start the car.

For most people jumping the car is the best option and now that you have read this you know how to do it properly.

Also, you know you can use a mower in a pinch or get a portable jumping pack, so you won’t ever get caught unprepared with a dead battery again.

Car Battery Won’t Hold A Charge: Why And What To Do?

Your car battery is one of the key components in running your car. It is especially important when you go to start the car.

The battery provides all the electrical energy to run anything in your car that uses electricity. It runs the headlights, radio, and even the starter.

That is why if your  car battery won’t hold a charge it is a major issue because your car won’t start and you will have to jump it all the time. There are a handful of reasons why your car battery won’t hold a charge and also a few things you can do about it.

What to do if car battery won’t hold a charge?

Reasons Won’t Hold A Charge

1. One of the most common reasons why your car battery didn’t hold a charge is because something got left on.

If your dome light comes on when you open your door, then it might have got left on during the night by the door not getting closed all the way.

Also, your headlights might have got left on draining the battery. You will learn how to figure out if this is the case later on in the article.

2. Another reason for your battery not holding a charge is that you might have a parasitic drain in your vehicle. A parasitic drain is when you have something wrong in your electrical system that puts a small draw on the battery.

If you drive your car normally, then the alternator probably charges the battery enough that you may not notice this drain. If your car sits for a few days however, then it may end up dead when you go to start it from the drain.

A parasitic drain could be going on for months before you are aware of it and tracking one down can be a major headache.

3. A third reason for your battery to not be holding a charge is a bad alternator or serpentine belt. The alternator is what charges the battery while you are driving.

It is like a small generator and takes some of the mechanical energy of the engine spinning and turns it into an electrical energy.

If the alternator is going bad, then it may not be converting as much energy to the battery. This will eventually lead to the battery wearing down and not holding a charge.

Also, if the belt connecting the c to the motor is loose, then the alternator may not be working at its full potential and this too will lead to the battery not getting recharged all the way while driving.

4. The last reason for a car battery not holding a charge is that it is old. As a car battery ages the cells can not hold as much energy. Most batteries have dates when they were bought and if it has been awhile then that could be a reason.

Also, dirty connectors on the terminals can cause the battery to not get charged all the way and lead to it dying.

What To Do If Your Car Battery Won’t Hold A Charge

If your car battery is not holding a charge, then there are a few things you can do depending on why it is not holding a charge.

First you need to make sure the battery didn’t just die from something getting left on. If that is why it died, then you shouldn’t need to do anything to your car after jumping it. It will recharge on its own.

If it is a parisitic drain, then you might not notice it again until the car has sit again. If this keeps happening, then you have to try to find the drain to stop it from happening. If that is not the reason, then you need to find the reason.

If the car battery is not holding a charge from a bad alternator or serpentine belt, then you need to replace that part. You can use a volt meter and battery tester to see if the alternator is charging the battery while the car is running.

You can try to recharge it with best battery maintainer, maybe it will help your battery keep alive.

Most auto shops such as Auto Zone will do this for you for free. If it is the alternator, then you now know the problem and know it needs replaced. If it isn’t then you can move on to other things.

One of the things you can do even if you don’t know the reason is clean all the connectors on the battery. This way you will know that they are making contact.

Also, if the battery has been drained multiple times, then you can put it on a slow charger and this will help it hold a charge better.

If your battery is old, then you have a few options of things you can do. Most people might not have the money to replace their battery whenever it gets old, and the battery is something you forget about until it doesn’t work.

If you have an old battery and can’t afford to replace it, then you can try recharging the cells. To do this you buy a kit and then remove the battery cover to expose the cells.

You add the liquid from the kit using the directions and then put the cover back on. This gives the battery more conductive juice to help it hold a charge again and last a little longer.

Recharging a battery though is only a temporary fix and recharged batteries don’t hold a charge as well as new ones.

Conclusion

Enjoy your trip!!!

Enjoy your trip!!!

There are a lot of reasons why car battery won’t hold a charge. It could be something as simple as something just getting left on one time killing the battery, or it could be that you have a small parasitic drain weakening the battery.

Also, it might be that the battery isn’t getting charged all the way due to a bad alternator. Lastly it might just be an old battery.

Depending on the reason that the battery isn’t holding a charge, you can do a few things. You can replace the battery if it is old or try recharging it.

If the alternator is going bad, then you can replace it. If it is a parasitic drain, then you can hunt it down and stop it.

Lastly, if the battery was drained just from lights getting left on, you shouldn’t have to do anything besides drive some after jumping the car.

PORTER-CABLE 7346SP 6-Inch Random Orbit Sander with Polishing Pad

Porter Cable 7346SP

Porter Cable 7346SP

Now we can look at the Porter Cable 7346SP and see why a lot of users like it. To start with it comes ready to use out of the box, which is nice. It comes with a sanding disc and a polishing pad.

It also comes with a side handle attachment and wrench to change the pads. The side handle is handy because it gives you better control when using the sander and also helps it cause less wear on your body.

This particular orbital sander is nice and compact. Users love that it is only 11.5”x10.5”x6”. This makes it, so it is easy to put in a toolbox or carrying bag if you need to take it on a job. Also, at 6 pounds you won’t get tired using it. The motor that is in the porter cable 7346SP is sturdy and has variable speed ranging from 2500-6800 OPM or Orbits per minute.

Also, the build quality is exceptional. People love how durable it is, and porter stands behind there product offering a full one year warranty with a limited three year one. This means if any issues come about you shouldn’t have any problem getting them resolved. Some people have had issues with the bearings going bad in newer models. People fear that they may be starting to slack in quality, but it might just have been a bad batch.

Another thing about this random orbit sander is it is swirl free and can accept accessories that are 5/16-24 spindle thread. The handle mentioned earlier is also in two positions and offers an excellent counterbalance.

The Porter Cable 7346SP is run off of 4 amp AC at 120 volts meaning that you can use it anywhere. Some people might want a battery powered one so they can take it wherever they want without the hassle of a cord, but the good thing about it running with a cable is it will never be dead on you.

Users love this model for all the things it can do. If you need other pads besides the ones that it comes with they are easy to get. You can get a great result on cars paint according to some users and most also love how well this wet sands.

PORTER-CABLE 7424XP 6-Inch Variable-Speed Polisher

Porter Cable 7424XP

Porter Cable 7424XP

Now we will look at the Porter Cable 7424XP. It is similar to the porter cable 7346SP. The motor is of the same high quality, and it comes with the same warranty plan. The motor still runs off 120 volts and at a variable speed of 2500-6800 OPM.

It even comes with similar things out of the box such as the wrench, handles, and polishing pad. However, one thing it does not come with is a sanding pad. This means if you want to sand you will have to buy a sanding pad separately.

Like the 7346SP the 7424XP can take any pads and accessories that have a 5/16 – 24 spindle thread meaning that getting other pads isn’t an issue, but it is annoying that you can’t sand right out of the box.

This model is also easy to use and balanced well, especially when using the two position handle attachment. The size of this unit is very similar. It is lighter at 5.75 pounds, but it is longer measuring 14”x6.5”x6”. This extra length has made it harder for some people to stick it in there bag and take it on the go.

This still is a good variable speed orbital sander though. The pads still work just as well an is swirl free. The build quality is also just as good. Many users are happy with how long this model has lasted for them.

It is a workhorse and can do any sanding or polishing you need. The fact that you can use it without the handle attachment is helpful and cuts down some of the size and weight. If you like switching hands for different angles, then you probably won’t want to use the handle.

Also, the speed controls being a wheel makes it very easy to choose the speeds you want. This is handy because you don’t have to guess what rate you have it set too.

Which Should You Get?

Which is better between porter cable 7346sp vs 7424xp?

Which is better between porter cable 7346sp vs 7424xp?

Choosing between the two can be hard because they are so similar, but the porter cable 7424XP is the better option for most people.

The fact that it is lighter means that it is easier to control and also easier to take with you. On top of this, it is the more durable option. While the 7346SP is a good sander, it usually doesn’t last as long as the 7424XP. When buying a tool you want one that is top quality and can be a workhorse for you. The 7424XP is just that.

Also, when it comes to speed controls, the 7424XP is more comfortable to set.

Lastly, you are probably going to want to buy new pads anyways, so the fact that the 7424XP doesn’t come with a dedicated sander pad isn’t that big of a deal. The pads out of the box are cheap, and while they can work to get the best results and no swirls or marks left behind, you will want to get some better pads.

However, they will both do the same job, so you can choose the 7346SP because cuttingly it cost less and comes with a sanding pad.

Uses for Orbital Sander

After comparing the sanders though you should probably have a rough idea of the uses for one. Well, you can do all kinds of things with an orbital sander, and sanding is only one of those things.

They are suitable for sanding wood to get a smooth finish before staining or removing the old stain, but you can also use them on other surfaces besides timber. You can use them to sand down paint on your car for example if you want to repaint it or you can even smooth down other metal.

Outside of sanding you can also polish things with an orbital sander. The rapid circular motion with the right pad can brighten up metal services or even painted ones. With an orbital sander, you can get a bright shiny finish fast on things.

No matter if you are polishing or sanding an orbital sander will make the job quicker and also do it evenly where by hand it takes longer and may not end up even.

Conclusion

Now you know what is the difference between porter cable 7346sp vs 7424xp, and have a good idea of what to look for when buying one. Just look at the speeds, the size, and think about what you will use it for. Either of these Porter Cable ones will do excellent work and provide you with a job well done.

Can You Paint Over Clear Coat On A Car?

For a car, the paint job has many layers. There is the bare metal which some primer is sprayed onto. After that, the base coat goes on.

This is the main color that you see. On top of the base coat goes a clear coat. The clear coat protects the paint under it and the metal panels of the car.

Most people might not realize that there is a clear coat on their car and just think the mainbase coat is the final layer. One question that comes up a lot though, is can you paint over clear coat on a car?

After reading this article you will have a better answer to this question, which has many opinions.

Reason To Repaint Car

You may be wondering if the clear coat is there to protect the paint underneath it, then why would you need to repaint the car. Well over time the clear coat can wear and damage can occur to the pain below it.

Also, if your car ends up with deep scratches, that can’t be buffed out, then you might need to repaint a section of your car.

One other reason is you might just get tired of the color that the car currently is. Maybe you have found your dream car model and year wise, but it isn’t the color you want. In that case, you would need to paint it.

Should you Paint Over Clear Coat

Now that you know why you might need or want to repaint a car it is time to get to the question at hand which is should you paint over the clear coat.

Well, the short answer is no because the clear coat is there to protect the paint and therefore makes it hard for other things, including paint, to stick to it.

However, there are exceptions to this no rule. Most of the time, the clear coat does not need to be completely removed to paint over it and most of the time the car does not need to be completely primed again.

If you are just performing touch up work, then you only need to scuff the clear coat to make the new paint adhere.

However, if you don’t scuff it enough or paint too thick, then the new paint will be noticeable. Generally, you have to paint a larger area, then just the scratched part to blend the paint well.

If you are changing the color of the car however, then it is a good idea to not paint over the clear coat. By painting over the clear coat on large areas, it can lead to waving and the old color showing thru.

This is because you need a lot more paint to cover the old color, especially if there is a major color change.

In this instance, you will want to completely remove the clear coat and make sure you are down to the old base layer. Then you will want to apply a primer before adding the new base coat color and new clear coat.

How to Paint Over Clear Coat

Maybe you’re interested:

If you decided to paint over the clear coat, then there are still a few steps you should take.

First, make sure your car is completely clean. The reason you do this is you don’t want any imperfections caused in the new paint or for your car to get scratched while you are trying to repaint it.

Then you have to scuff up the old clear coat to make sure the new paint will stick. The way you scuff up the clear coat is you take some sandpaper or a sanding block. You get it wet and then go over the areas that you are going to paint.

It is a good idea to tape off the trim and other areas that you don’t want to be sanded, so you don’t mess up other parts of the car.

You could also remove the part of the car that is getting repainted if it is a large area and you want to do that.

The grit of paper you use should start out with around 300 and work over it. Then you want to use something finer like an 800 to make sure it is extra scuffed.

You don’t have to remove all the clear coat, but you want to make sure you get it scuffed good.

Also, if you are going to paint over the clear coat you want to make sure the sanding is done evenly. If you get down to the base coat at any part, then you will have to remove all the clear coat or it won’t look good.

Once it is all scuffed up good you want to do one last good washing of the area to make sure all the loose particles are gone. Then it is time to get the new paint out.

A lot of people will use a spray gun or spray paint to paint over the scuffed up area. You just want to make sure to use smooth even motions so the paint will go on evenly.

You don’t want it to go on too thick in spots or to run. After you are done painting it you need to let it dry completely.

Then you can apply some new clear coat to protect your new paint job. If you took your car apart, then you can put it back together after the clear coat has dried.

If you only taped off, then make sure the paint and the clear coat is drybefore removing the tape.

Conclusion

So, to answer the question of can you paint over clear coat on a car, the answer is no. However, there are sometimes when you can get away with it if you do it right.

If you are changing the color or doing a large area, then you really should remove all the clear coat and reprime to get the best paint job.

If you are doing a smaller area of painting though or an area that is hard to see, then you can get away with painting over the clear coat if you do it right. Be sure to scuff up the old clear coat good to make sure the paint will stick well.

Also, be sure to take your time and apply the paint evenly to prevent warped looks. As long as you follow these steps in most situations you should be able to paint over your clear coat and not have people notice.
