Have you put a multi-meter on the battery when running to check voltage? Or are you just looking at the guage?

Since you have already thrown a PCM at I would imagine we can eliminate it, I would have been more inclined to put an alternator on it, that would be my suggestion. Worst case scenario take it to one of the auto parts stores that test them and have it tested before you buy a new one.
Good Luck!

Voltage regulator is built into the PCM as far as I know. In any event test the alternator as starting point.

Okay you didn't mention the alternator before. Is the PCM remanufactured or junk yard?
