CYCLE ELECTRIC INC - RECTIFYING REGULATOR - HARLEY DAVIDSONRectifying Regulator Harley Davidson Highlights Controls voltage on Harley Davidson and Buell alternators, unlike other rectifiers or regulators that dump to ground and cause maximum stator current and higher temperatures Cycle Electric rectifying regulators block current to control voltage; this reduces stator current, resulting in low temperature and less drag on the motor, which means more efficient operation Made in the USA + Fitment 2004 2005
