Alternator question.

Ok, so, my alternator is now charging at +12.9V.

It has slowly been going down. Now, I am running a lot more electrical stuff and it can't seem to keep up. I know a lot of people swap in the FD alternator, but are there any backets or anything that would let me swap in something like an AC Delco? Or something like that?

I do have PS and AC. No air-pump though.

Thanks!

N/M.

I am going with an FD alternator. Time to search!

I have FC dual alternator pulley. Will it work with the FD alternator?

The FC pulley will work if you can get the hole drilled to make it a little bigger so it can fit the FD alt. shaft. If you don't want to go through with the hassle of finding a way to widen the hole, you could buy a dual pulley made for FD alternators from banzaitoyota.

The FC alt pulley is to large in diameter for the FD alt to charge right at idle. Basically it will underdrive the alternator. You can use it untill you contact BanziRacing for the right sized pulley.

Thanks. I will probably just buy one and sell my FC one to a friend around here for $10 or something.
