How to test alternator on 2013 Dodge Dart?
Dodge Dart Bad Alternator Diagnosis
- Get a multimeter.
- Set it to read voltage.
- With your Dart turned off, you’ll connect the negative side of the meter to the negative battery post or wire.
- Now that you have this baseline, it’s time to turn the engine on.
- With the engine just fired up, you should get over 14.2 volts.
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.
What happens when an alternator overcharges the battery?
Battery. Alternators that overcharge will typically produce excess voltage to the battery, making the battery case swell up, become very hot and lose its electrolyte through boiling. Improperly jump-starting the vehicle can send a surge through the battery that destroys one or more cells in the battery or shorts it out.
What is the terminal at 10 o’clock on a Dodge alternator?
On the alternator, the terminal at 10 o’clock would be the (-) field circuit and 11 o’clock would be the (+) field circuit. below is a link to the wire diagram of the basic Mopar charging.
Why is my Dodge talk overcharging my battery?
The positive lead to the voltage regulator should be a switched positive and should read as close to the same voltage as the battery. If someone has wired the positive VR supply to the reduced side of the ballast then you will have an overcharge situation as the ballast will drop voltage and the vR will see this as a low charge and up the charging.
Is it possible for an alternator to over charge?
You are correct, 18 volts is much too high, but an alternator can not cause over-charging unless it is assembled incorrectly with one of the brushes grounded through its mounting screw. Over-charging is caused by the voltage regulator driving the alternator too hard.

Do you need a positive or negative orientation for the alternator?
In addition, there is no positive/negative orientation required for the field terminals on the alternator. Either wire from the VR can be connected to any of the field terminals. As was said earlier one of the wires to the field terminals should be switched full system voltage which is a continuation of the switched wire going to the VR.
