Don't know why this thread was overlooked.

Have you downloaded the free technical manuals? They have troubleshooting sections and detailed wiring diagrams.

The fuse for the heater fan also controls the excitor circuit for the GEN1 alternator.

In a stock system, the front battery is controlled by the driverside alternator (GEN1) and the rear battery is controlled by the passenger alternator (GEN2)

No need to double post a question (also it against the website rules)

Your post will get a better response in the CUCV forum. I posted some things to check in your other thread.
