CYCLE ELECTRIC INC Rectifying Regulator — 12V, 38A/48A – 97-01 Touring, 01 CVO

The rectifying regulator controls voltage on Harley-Davidson and Buell alternators, preventing the common issue of dumping excess current to ground that increases stator current and raises temperatures.

Unlike regulators that simply dump current, this rectifying regulator blocks current to manage voltage, reducing stator current and lowering operating temperature, which reduces drag on the motor and improves efficiency. ⚡

It provides more stable electrical output under load and helps extend alternator life through improved thermal behavior.
