So my alternator is intermittently overcharging. The voltmeter will peg for 30 seconds, then come back down and be fine for an hour, then the voltmeter will peg for a minute. Went to get it tested, but the battery tested bad, so I had to replace it first. With the new battery, the alternator tested as bad. Here's the challenge:
So, is there a small 1-wire alternator that I can go to the AutoZone and say, "Give me an alternator for a 1987 Buick Yada Yada with the X.X liter motor" and that thing will work?
- According to the old dog at NAPA, it's an 80s-90s GM, but clocked and pulleyed differently from stock. And there's a little box on top that appears to convert it from 3-wire to 1-wire.
- No numbers on it except a rebuilder sticker. The rebuilder went out of business. The company that replaced it says those parts are long since discontinued. He was kind enough to offer to sell me a $275 replacement alternator. It won't arrive in time for a planned trip.
- The bracket setup on my car is a little different from the DanR and Jose kit standards. Unsure of what bracket it is, but the alternator is on the passenger side.
- The car isn't wired for anything but a 1-wire.
- All the auto parts stores ask for year, make and make and model, which I obviously don't have.
- Because it's overcharging, I can only assume it's that little box that's bad, so even if I found an exact replacement alternator, I'd have a 3-wire and a probably broken conversion box.
- There's a Delco 7127. It's great, but it's a good two inches larger in diameter, which would put it close to, if not in contact with the inner fender.
- Allegedly there's a Hitachi 14231 that can be converted to 1-wire (although it needs at least 1 additional wire (1-ish wire?))
- And saying Hitachi 14231 to the countermen has resulted in blank stares.
- Googling for cross references comes up with a lot of forklifts, which resulted in my own blank stares.
- And saying Hitachi 14231 to the countermen has resulted in blank stares.
- There's other stuff on Amazon I can order and hope I can receive it and make it work by Friday morning. But most involve finger-crossing and quick rewiring.
