I had to leave town and didn't get a chance to troubleshoot it yet, but I saw the voltage was right at 12 and not charging. It was probably running off just the battery. I restarted it later and the voltage was back to normal, then I restarted it again and it was back to 12. When I get home I'll have the alternator checked. I know the voltage regulation is controlled by the PCM but where's the regulator?
