Use your original pulley from the old alternator. It's smaller and free.

the alternator does have my stock original pulley on it, i swapped it cuzz it didnt come with one. did the powermaster originally come with a bigger pulley other than stock size ?

Now that, I do not know. The 3g I got came with a huge pulley. Car wouldn't charge at all. My stock pulley was actually very small and may not have been original now that I think about it. It was way to clean and very small in diameter. Sorry for the confusion but I do still think you need a smaller pulley. Where to get it is another story...maybe picknpull or someone on the board might have one laying around. I'll check my old box of parts when I get home. If I find one I'll just give it to you.
Good luck!

koo, thanks a lot, every help is appreciated. hopefully the pulley is the problem, cuz i jus installed an electric fan on it too and would hate to put the stock one back on.
