I have seen a few related posts on other sites but no answers. I hope we can figure this out.
The problem: Alternator not producing enough voltage to charge battery or keep car running (only ~12v)
What I have tried:
- Having alternator bench tested (twice) and it tests good
- Voltage regulator is internal and tests good
- Tested alternator while installed, and it does not produce enough voltage
- Tested the charging circuit up to the fuse box and found no continuity or ground issues
A clue:
- I accidentally left the #1 fuse out of the dash fuse box, and the car started but then died after a minute. When I replaced the fuse and restarted the car, the alternator was producing 14+v. Problem solved? No. The next day, I drove the car and ended up stranded with a dead battery. I tried the fuse trick again today, and it did the same thing.
Any ideas? Is this a relay issue? I don't think there is a computer in this car - it's carbureted.
Thanks!
