I did a 3G 130 amp alternator install today, followed the instructions to a "T", it all went smooth, even the "work" on the bracket.. Problem is, it behaves just like the 2g, for the most part anyhoo, it seems to get to a normal charge level quicker, but at idle, 650 rpm or so, it still goes below 12v, with NO accessories running.
I really want to get this to working properly, as I am gonna put an electric fan in.
What could this be? I doubt it's the alt, b/c it does well at 1300rpm and up.
My underdrive crank pulley is tiny.. I have had a few people look at it in disbelief when they see its size, it was on when I bought the car..Does the underdrive pulley really do all that much?
Will I have to change a pulley on the alt, or maybe acquire a larger crank pulley? If that is the case, does anyone have one they are willing to sell?
thanks for the read, and any advice...
