Rectifier Regulator For Harley Davidson XL 77-81 - OEM 74504-78

Controls the voltage in Harley-Davidson alternators; unlike other rectifiers or regulators that discharge and cause maximum stator current and higher temperatures
Cycle's rectifier regulators block current up to the control voltage; this reduces stator current, resulting in lower temperatures and less friction in the motor, resulting in more efficient operation.
Made in the USA
