I put a Prestolite alternator on my Hawk today and for those who wonder what the difference is, here it is. At a leisurely idle, the generator showed negative 2 amps, the alternator with same load and everything, shows positive 10 amps. For putting around town after dark kind of driving, the alternator wins hands down.
