but if the signal from the car (alt control pair) is zero
then the alt could still be ok.
Yup - sure could. I always thought that if the alternator was turning, it was outputting juice (if working properly).

Such ain't the case.

I had a BAT light on my '94 once. Put a multimeter on the Field Output on the alternator, and got no reading. Bad alternator - right?

Put on a new PREMIUM built unit, and didn't even test it (wasn't a daily driver).

Couple days later, was in the mood for a cruise, and pulled the trigger. BAT LIGHT. HUH?

Chased EVERYthing with a multimeter for 3 1/2 hours, then a buddy at Advance said maybe a fuse is popped. Can't be, I said.

Ain't the first time I was wrong, probably won't be the last either.

Problemo solved,although the bat wire connector was firmly crimped to the insulation, but it had cracked and bent and no longer contacting the wire. I replaced the connector....14.4 volts
