About 30 second after starting my 1999 Jeep Wrangler, the check gauges light comes on and my battery gauge maxs out. It has been tested and it is overcharging. I replaced the alternator, the battery and the serpentine belt. That made no difference. I took it to a private mechanic who tested all the grounds, etc. for me, and they were fine. He could find no other explanation for the problem other than possibly replacing the computer, which would be quite expensive. Is there any way to be sure it is the computer before I spend that kind of money, or are there any other suggestions as to what the problem could be? Thank you.
You might want to call the dealer.
I think there was a service bulletin to replace the connectors in the back of the instrument cluster
