I've read as many posts as I can find regarding charging problems but still have a few questions.
94 XJ 4.0 - Not charging battery. Had generator bench tested. Checks out with same numbers as a new one.
Tried a new battery. Voltage drops when I start engine and continues to drop. Battery voltage recovers after engine is shut off.
Checked and cleaned all grounds, connections, terminal etc.
1) I read there are fuses in the PCM. I don't see anything in the FSM regarding fuses actually located in the PCM but do see fuses referenced for the generator in the power distribution module. Are these the fuses being referred to?
2) Regarding reading the voltage at the terminals on the back of the generator? Can someone explain the actual readings between the different terminals.
3) Is there a way, as a test, to bypass the PCM voltage regulator before I buy a new PCM.
Any other pertinent information would be greatly appreciated.
