Aftermarket Alternators

Rick's offers both new and rebuilt alternators for most Nippon Denso fan-cooled applications on motorcycles, ATVs, watercraft and snowmobiles. All rebuilt alternators require a core exchange.

We also offer replacement internal rectifiers (part #30-501) and voltage regulators (part #30-502) for most models , often the cheaper fix. Before replacing either, test the alternator to confirm which component actually failed.
