I upgraded my battery cables in my 98 (sport, 4.0, 4 door, auto transmission)with the set from jeepcables and am now having high voltage issues. The volts are fine when I start but about 30 seconds after shifting into drive, they spike up to 19 and stay there until I shut it down.
The internet told me that I probably have a bad ground. I cleaned and re-attached the grounds but am still having the same issue. I then replaced the alternator, still having the same issue. I checked the alternator field wires and am getting continuity between the terminals and the PCM.
I suck with electrical, thankfully this has been the first issue I have run into. What else should I be looking at? Is there a way to verify that the grounds are actually making good contact?
I noticed one of the PCM wires at the G101 ground has torn insulation. I am planning on splicing in a new piece of wire and terminal but am waiting on supplies. Could that be related to this?
Also, the battery was dead from sitting for so long so I had to jump it. I could be wrong but I am assuming a low battery wouldn't cause high voltage.
Thanks for any help
