Gentleman. I'm in the process of building a hot rod Crosley. I know, I know but boys just have to play. The motor is done and I have installed a Denso alternator from a 1987 Suzuki, bought new at local auto supply. I Know about the main line running back to battery, the the three terminals on the back have me confused. I have installed an idiot light in dash and know one goes there but the other two ? Don't want to screw up a new alternator.
