Voltage Regulator Rectifier with Harness Adapter Cable for GY6 50cc, 125cc, 150cc Scooter, Moped & ATV

GOOFIT 12V Regulator & Harness Combo – Complete Charging Solution

Eliminate charging failures for good. The GOOFIT 4-Wire Voltage Regulator & Adapter Kit is a comprehensive electrical upgrade designed for the GY6 50cc to 150cc engine platform. This kit includes both a high-performance 12V rectifier and a heavy-duty harness adapter cable, ensuring you have everything needed to restore stable power to your battery and lighting system.

Built with advanced circuit design, this regulator provides a precise 12.5–13V output at idle and moves to a steady 14.5V charging state to keep your lead-acid battery healthy. The high-temperature resistant housing is engineered for the cramped, high-heat engine bays of modern scooters and ATVs, preventing the thermal failure common in factory components.
