Where is the alternator on a Dodge truck?

Open the hood of your Dodge with the engine turned off. Also check to make certain that all other switches and/or electrical components have been turned off. Locate the alternator. Depending on your model of Dodge, the location will vary. It will, though, have a belt running to it.

What does 12 volts mean on Dodge battery?

A reading below 12 volts may indicate your Dodge’s battery is the culprit. Charge the battery and, without running the car in the meantime, test it again the next day. Another low reading would mean that your battery is bad or that you have a short circuit in the wiring.

What should I do if my alternator doesn’t work?

The alternator should be quiet. If you hear squealing, rattling or grinding coming from the alternator, it will need repair or replacement. Arthur Barnhouse has written numerous short stories, contributed content to various websites and was an invited speaker at a university symposium on creative writing.

What should the volts be on a Dodge Charger?

A reading around 12.5 or 12.8 volts is normal. A reading below 12 volts may indicate your Dodge’s battery is the culprit. Charge the battery and, without running the car in the meantime, test it again the next day.

What should be the output of a 300A alternator?

So if all of the electronics in your car, put together, only draw 60A, then your beastly 300A alternator will only produce 60A. The way that current works is that any given electrical component will only draw as much amperage as it needs to operate.

Can you replace an alternator with a high output alternator?

The good news is that replacing a factory alternator with a high output alternator, in and of itself, isn’t going to damage the rest of the electronics in your car, even if the new alternator is much, much bigger than the old one. As an example that trends closer to the ridiculous than the likely,…

What happens if the alternator on a Dodge truck is not working?

The alternator on your Dodge, whether it’s a car, truck or van, is an essential piece of its electrical system. In fact, if the alternator is not working perfectly, your Dodge will soon begin to experience serious problems. For example, with an improperly functioning alternator, the battery will quickly drain.

How many amps does a Chrysler alternator have?

This makes it a very easy job to convert your older Mopar 35-amp unit to a higher-amp Chrysler alternator. While 1961-’69 units were only offered from 35 amps up to 60 amps, the later units are rated between 60 amps and 78 amps. Any 1970-’87 Chrysler alternator will replace the earlier 1961-’69 alternators with a few modifications.

So if all of the electronics in your car, put together, only draw 60A, then your beastly 300A alternator will only produce 60A. The way that current works is that any given electrical component will only draw as much amperage as it needs to operate.

How is the amperage of an alternator determined?

The alternator generates enough amperage to meet the needs of the combined electrical system at any given time, and then each component draws its share. In order to determine how much amperage a component is going to draw, you can divide its wattage by the voltage of the system.

How does an alternator charge a charging system?

Basically, the voltage regulator completes the charging circuit and allows the alternator to charge the system. When a certain preset voltage is obtained, the regulator “opens” (or turns off) the circuit until the electrical system’s voltage drops below a certain point, then it turns on again.

What does the regulator on a Mopar Charger do?

The other connection on the regulator is a blue wire with a female plug end. This is the “IGN” Ignition side. Basically, the voltage regulator completes the charging circuit and allows the alternator to charge the system.

Where is the green wire on a Mopar Charger?

The GND brush is grounded with the brush mounting screw. the other brush is the (+) brush (or field) and attached to it is a green wire that routes over to the voltage regulator (which is behind or near the brake master cylinder) this green wire is connected at the voltage regulator at the “FLD” connection.

How do you remove an alternator from a car?

Once the belt is off just remove whatever bolts connect the alternator to the bracket and you’re good to go. Our model required the removal of three bolts: one at the front and two at the rear. With the old alternator in your hand you’re half way home.

How to replace an alternator on a 1995 GMC?

Somewhere on your vehicle there is a tensioner pulley. You’ll need to move it enough to slip the belt off the pulley. Our ’95 GMC has a standard spring-loaded GM tensioner that required us to pull it back with a wrench.

What should I do if my alternator is hot?

Really! First and most importantly: disconnect the battery. There may be several wires or just one wire on your alternator, but rest assured that one of them is hot. If you don’t disconnect the battery, you’re very likely to end up grounding a live wire during the process.

How to repair the ABS and speed sensor in a Dodge Dakota?

Learn how to read diagnostic trouble code to evaluate trouble indicators and fix broken sensors. So if your speed sensor or ABS brake system are on the fritz in your Dodge Dakota truck, watch this video and learn how to check and fix them. Want to master Microsoft Excel and take your work-from-home job prospects to the next level?

What causes an alternator to have a bad connection?

When there is a defective connection between the battery and the alternator, charging current will be forced to find an alternate route to flow out toward the battery. A defective connection may be caused by corrosion or an open circuit from a break in several battery cable stands.

What to do if your alternator is over charging the battery?

Ask an assistant to start the engine and hold engine speed at about 1500 RPM. Measure voltage across the battery with your DMM. You should get 0.5 to 2 volts higher than base voltage. If you are getting more than 2 volts above base voltage, most likely your alternator is over-charging the battery or the battery is faulty.
