Description

Replace a failed or overcharging regulator/rectifier on your 139QMB 50cc scooter with this Full Wave Voltage Regulator/Rectifier. A faulty regulator causes battery drain, overcharging, or a complete no-charge condition — this is a direct plug-in replacement using the stock female whip connector. No wiring modifications required.
