Should I put alternator pulley back on?

MTU 50 · 03-21-2001, 07:37 PM

I have Underdrive pullies on my car and I am definitely going to change back to a stock sized pulley on the alternator.

It just isn't worth the small power gain of slowing the alternator to put up with charging problems.

My car doesn't charge at idle at all and there is noticable dimming of the headlights at night. At night with the lights on and say the heater going at full I am drawing a ton and there is a noticable lack of juice.

It is possibly the pullies of today are better than the ones I have. My Pullies were put on by the original owner back in 1994 I believe, and I have heard earlier pullies slowed the accessories down a little too much.

BTW-IGNORE the "March Pulley's" in my sig. I was going to get a nice set of those about a year ago, but didn't have the money. The pulley's I have are pieces of junk compared to March, which are very high quality IMO.

I'd better change that
