Hey guys I've got a 91 Carrera elite 205, 454 hardin marine engine and the alternator is giving me troubles. boat will start up and run but won't shut off until I remove the IGN wire that goes from the alt to my terminal block setup. So I'm looking for a replacement. My current alternator is a prestolite 37A not sure if its a 1 wire or 2, (not familiar with alternators). Got some pics of the one I pulled out here, any help would be great in what direction I should go. Also its only a 10Awg wire that feeds it fyi.
