55150 Voltage regulator/rectifier. Black

This Compu-Fire voltage regulator and rectifier is a high-quality replacement for the stock 38 Amp single-phase alternator systems found on many Harleys. Finished in a clean black, it is designed to fit 1998 to 2002 Big Twin models that utilize a single-phase charging setup. It is an excellent choice for riders who want to maintain their stock charging configuration but want the added reliability and build quality that Compu-Fire provides. The regulator ensures your battery stays properly charged while protecting your bike's electrical components from voltage spikes. It is a rugged, dependable part that looks great and performs even better under the demanding conditions of the open road.
