“I have helped hundreds of customers solve charging issues", there are many issues that are not covered in buying a regulator and plug separately. If your mechanic installs one of the external regulator kits and it does not have our exclusive plug retaining clip, it is not a Quick Start kit and your plug will eventually fall out. Save the headache, get the support plus the correct parts. Don't piece this together without the support, buy our kit and let someone else have the headache!

Engine Control Unit (Computer).

The computer is often called the ECC, ECM, EEC, or PCM. Often the alternator voltage regulator, or field control in the computer will fail, leaving you with a dead charging system where your alternator doesn't work, yet your engine runs just good. Before our external voltage regulator conversion kit, the computer would need to be replaced right away at a much higher cost.

In order to avoid costly computer replacement and get your alternator working, you can simply bypass the internal Alternator Regulator Control Module using our simple External Voltage Regulator conversion kit.

How to test your alternator on the vehicle: FOR TECH HELP MESSAGE US

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 14.5 volts. If you want to adjust the voltage regulator you use the screw on the back, but be sure the metal case of the voltage regulator is grounded while you adjust it.
