The daughter was driving our early 97 TJ, and the check gauge light came on; she looked and could not see why. When I went to start it, it took much longer than normal to start, and I saw the voltage gauge wasn't up to 14v per usual. The check gauge light did not come back on.
I was assuming I had an alternator issue, but I am seeing a few posts saying hard start plus not charging means it's the computers; what is my diagnostics process? I am confused between PCM and ECM, does it have one unit serving both functions? Is there a rebuilder that is better than the others? Is anything here one of the unique early 97 issues?
Thanks,
Patton
