I have a '97 with the 4.0L and the aw4, I have ocassionally had voltage spikes for the past say 3 years. The first few times I had it I just thought that it was an alternator issue, so I installed a new bosch alternator and a optima. Problem solved, for a couple of years, then the same issue came back 10x worse now. Gauges go nuts, everything electrical speeds up or gets brighter, engine runs like a champ, but it throws off the transmission shifting.
So I replaced the POS bosch alternator, that was no longer under warranty, with the V8 ZJ alternator, works great; but still have the same problems. I replaced the computer, same problems. Optima is still good. Cleaned all power and ground wires except for the end attached to the block because its a PITA to get to, shot it with electric parts cleaner. I next plan on replacing the belt cause it slips when the A/C comes on, and the grounding strap that runs from the firewall to the block. Have I missed anything or is there anything else that I would need to check??? This is a DD, and I have too much invested to give up on the thing.
