Last spring we went for a trip to the Badlands in IN, my father-in-law took his XJ into too deep of a water hole there & ever since the alternator has never charged the battery. Jeep never died in the hole, but we assume this was the culprit ( water over hood).
This is a 1991 4.0L HO XJ with an 87 5-speed & 4wd axles. Jeep ran fine till that day, now does not charge. We have replaced the alternator 3 times now (verified last two were good before instaling), and also replaced the wiring harness coming off of the alternator to the ends of those wires.
When read with a multimeter, the two small wires on the back read 1.4v & the large wire reads 10v (same as battery @ that time).
What tells the alternator to charge???
We are tired of stopping wheeling to swap out batteries all the time.
