Since 1987 for Dodge and Chrysler vehicles and since 1991 for Jeep Family vehicles have alternators that are controlled by the Alternator Voltage Regulator Control Module inside the vehicle computer. 
CAUTION: vehicles after 2005 may also require a modified driver as well. Email your vehicles year, make, model, engine info for your vehicle and we will tell you

Engine Control Unit (Computer).

The computer is often called the ECC, ECM, EEC, or PCM. Often the alternator voltage regulator, or field control module, in the computer will fail, leaving you with a dead charging system situation where your alternator doesn't work, yet your engine runs just fine. To get your alternator working your entire computer would need to be replaced.

In a bind?, to get your alternator working you can bypass the internal Alternator Voltage Regulator Control inside the computer by using our External Voltage Regulator By-Pass kit.

How to test your alternator on the vehicle:

To check to see if your alternator is working, unplug or remove the two field wires from the back of the alternator. Then ground one of the field terminals on the alternator and jumper the other field terminal to the positive battery post on the back of the alternator. It does not matter which terminal is grounded and which one get positive power. When you connect the ground and positive wires to the field terminals you will get a small spark, this is normal. This is by-passing the voltage control and will cause your alternator to run full blast, if it is working. Put a multi-meter on your battery and run your engine on high idle, do not allow your alternator to charge the battery much over 16 volts. If you find that your alternator is charging when you do this procedure, but does not charge when you connect it back to the computer, this kit will get your alternator working and charging at the proper voltage. The voltage regulator is preset at 14.3 volts. If you want to adjust the voltage regulator you use the screw on the back, use small  adjustments at a time,  but be sure the metal case of the voltage regulator is grounded to the alternator & battery while you adjust it.
