[Stang_Crazy]

I finally got the chance to get my pulleys on the stang. I only changed the water pump pulley and the crank pulley. I DID NOT change the alternator pulley. Now, when I start the car, the battery gauge shows the volts in the red and shortly after, the battery dies. Even when I give it gas, it seems like the battery doesn't charge up. I just bought the battery last september so it should still be fine.

I was planning on buying a 140 amp alternator and then putting the aftermarket pulley on it. If I do this, will I still have charging problems??
