Cycle Electric Inc Rectifying Regulator

Control 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 U.S.A.
