OEM part number: 74504-78
Features:
- Control voltage on Harley-Davidson 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.
- Low voltage style features reduced charging voltage to prevent overcharging the battery.
- Made in the USA.
