Test TC-33B - Generator Field Not Switching Properly

WARNING: This page is about a different car, the 1995 Jeep Wrangler, 1995 Jeep Grand Cherokee, and 1995 Jeep Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Perform TEST TC-33A  before proceeding.
  1. Turn ignition off. Disconnect PCM connector. Disconnect generator harness from generator. Using an ohmmeter, test across generator field terminals for resistance. If resistance is less than 5.0 ohms, go to next step. If resistance is 5.0 ohms or greater, replace the generator.
  2. With DRB in ohmmeter mode, check resistance in field circuit of generator harness. If resistance is less than 5.0 ohms, repair short to ground in field driver circuit (Dark Green wire). If resistance is 5.0 ohms or more, replace PCM.
