- 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
- Before replacing regulator, test stator for shorts to ground and proper AC output. If the stator is bad, a complete charging system upgrade part is recommended.
