Don't know the answer to that question.

Here's the complete diagnostic chapter from the WSM. It should guide you to the repair. Keep us updated, if you would.

Will do. Nothing is more frustrating than finding a thread discussing the problem you have, then the discussion just ENDS.

PROBLEM SOLVED!!!

I've been chasing electrical causes, but it was the BELT TENSIONER!!!

I started the engine and applied pressure with a tensioner tool, and the alternator is working JUST FINE!

Thanks for the update. Your thread is now marked as being solved.

Well, nuts.

The problem remains. Looks like time to start the diagnostics from scratch and go all the way through.

It would simply things if I could find a tester that would plug into the control jack (C102A) on the alternator.

With the plug from the PCM disconnected, should I see output from the B+ stud?

Did you ever get this resolved?
