Another Alternator Wiring Post

[farside847]

Sorry to start another alternator wiring thread, but i could not find an answer searching...

I believe I have a mystery non-stock alternator, that only has two wires attached (red and black). it works great and has been there for years, but i would love to have my battery gauge work again and I believe it is not working because the other wires are not hooked up.

The alternator is a "Delco Remy" with a few numbers on it that are pretty warn. i will attach some pics of it. It looks to be a 55amp. But I really dont know the model. Maybe some of the experts online can identify on sight?

Luckily, the original wiring is still intact, and just taped off. The alternator has a R and F terminal unused. I was thinking of connecting the blue wire to the F connector, and the yellowish wire to the R connector. Before i hooked up my Blue and yellow(ish) wire i wanted to check to see if doing so might fry something. I dont want to damage the alternator, wiring or regulator. Is this the right thing to do?

i am wondering why the alternator was originally hooked up this way. i wonder if the regulator might be bad?

thanks for any help!
