Looks like I'm going to put an electric fan on my 'bird. My question is, will I have to get a new alternator for the car? Right now, I've got an 80 amp external regulator alt. on the car. The car has the following electrical items on it: headlights, taillights, dash lights, heater w/fan, turn signals, dome light, radio w/cd player. No air conditioning or huge speakers. Do any of you guys know how I can figure up my total amp output? Or if anyone knows, I can get away with a 13.5 amp fan with all this stuff?
