Well I think the old alternator was kinda weak because the battery output seemed way better also pry because of the larger alternator. Had to pound the crap out of the top bracket in order to get it in place due to the little round metal piece in the rear hole. (get your minds out of the gutter) After I hit it for a bit it moved and went right into place! My next upgrade will be the electric fan. Now about the larger wire, for the alternator, could I get this at Quadratec?
