Current Output Test
CAUTION:
Generator has 2 field terminals: generator field driver (Dark Green wire) terminal No. 2 and generator field source (Dark Green/Orange wire on Cherokee, Light Blue/Red wire on Grand Cherokee and White/Dark Blue wire on Wrangler) terminal No. 1. DO NOT connect generator field source terminal to ground.
Perform VOLTAGE DROP TEST before continuing with this test. Perform test soon after starting engine, as charging amperage will drop quickly. A volt/amp tester equipped with both a battery load control (carbon pile rheostat) and an inductive type pick-up clamp is required to perform this test. Follow tester manufacturer's instructions to perform current output test.
