Hi
Vehicle is a 98 XJ LTD, 4.0, AT, Dana 30
I've been having ongoing issues with charging, and holding a charge.
The check gauges light was coming on and the volt meter was dropping to zero, both intermittently.
I replaced the battery, then had the alternator rebuilt from a quality local rebuilder, and it solved the problem. 3-4 months go by , and now it's doing it again.
I charged the battery and got it running. At idle the Alt is putting out about 13.5V, battery tests good with load tester. I loaded the charging system by turning on AC, head lights, rear defrost and stereo. Now the Alt output is down to 12.3V at idle. If I raise the RPM's to 2000rpm, the output raises minimally to 12.5V
What does everyone think? New Alternator, bad grounds, or Regulator in PCM?
Thanks,
Don
