Heavy Duty Chrysler External Voltage Regulator Conversion Kit
http://www.alternatorparts.com/external-voltage-regulator-high-output-alternator-kit.html   

Since about 1987 most Dodge and Chrysler Family vehicles have been equipped with externally voltage regulated, ER, alternators, with the voltage regulator control located in the Power Module of the Engine Control Unit, ECU. This is often called the ECC, ECM, EEC, or PCM. Often, especially after installing a high output alternator, the alternator field coil control module in the ECU will fail, leaving you with a charging system where your alternator doesn't work, or it overcharges or undercharges, but does not significantly change other functions controlled by the power module and your engine still runs as it should. Before our ECU bypass kit the entire ECU would have to be replaced at a cost of between $300 and $800....plus labor!.
The Solution

In order to avoid costly ECU repairs, you can simply bypass the internal alternator field module using our simple external voltage regulator conversion kit.

External Voltage Regulator Conversion Kit

We now provide all you need to get your Chrysler family vehicle's alternator working or get a high voltage condition back in control plus you can prevent ECU failure from installing a high output alternator. The External Voltage Regulator Conversion Kit comes complete with a reliable Transpo™ Adjustable, External Voltage Regulator. With the External Voltage Regulator Conversion kit you can save hundreds of dollars on costly ECU repairs and vehicle down time..

ECU troubleshooting: If the battery voltage is between 12.8V and 14.7V, your ECU Power Module should be fine. If you alternator is not working or your alternator voltage is above 15 volts you have a problem with your ECU. If your voltage is low you may have an ECU problem or your bridge rectifier in the alternator is failing.
