There are only three wires, the two small field wires are interchangeable, and the fat output wire bolted that's on. Chrysler charging systems have always been very reliable and easy to troubleshoot. Measure the voltage on the green wire while the engine is running. You should find less than battery voltage, but not 0 volts. Grounding that green wire will make it charge wide open. Lights will get bright and battery voltage will go up to over 15.0 volts. Don't do that for very long and don't increase engine speed too much to prevent damaging the Engine Computer and any light bulbs that are turned on. Holler back and let me know if that worked.
