4-Pin Voltage Regulator Rectifier – GY6 50–150CC ATV Moped
4-Pin Voltage Regulator Rectifier – GY6 50–150CC ATV Moped
4-Pin Full Wave Voltage Regulator Rectifier – GY6 50, 80, 125 & 150CC
Keep your small-displacement engine's electrical system running smoothly with this full wave voltage regulator rectifier. Designed specifically for GY6-engine platforms, this 4-pin metal-construction unit converts AC current from your stator into stable DC power while regulating voltage output — protecting your battery, lights, and ignition components from overcharge damage.
Whether you're maintaining a moped, ATV, dirt bike, or motocross machine, this drop-in compatible rectifier is a cost-effective way to restore proper charging system function. Made in China.
Key Features
- Full Wave Rectification: Converts all phases of AC output from the stator for more efficient charging versus half-wave designs.

Frequently Asked Questions
Q: Is this voltage regulator rectifier compatible with my GY6 125CC scooter?
A: Yes — this 4-pin full wave rectifier is designed for GY6-platform engines including 50CC, 80CC, 125CC, and 150CC configurations commonly used in mopeds, scooters, ATVs, and dirt bikes. Always confirm your vehicle uses a 4-pin AC stator connector before installing.
Q: What is the difference between a full wave rectifier and a half wave rectifier?
A: A full wave rectifier converts both the positive and negative cycles of the AC signal from your stator into DC power, providing more consistent and efficient charging output for your battery and electrical system compared to a half wave design, which only uses one half of the cycle.
Q: How do I know if my voltage regulator rectifier needs replacing?
A: Common signs include a battery that won't hold a charge, flickering lights, inconsistent electrical performance, or the battery overcharging. If your charging system tests show irregular voltage output, replacing the rectifier is a common first step in diagnosis.
Q: What is included in the package?
A: Each order includes 1 × 4-Pin Motorcycle Voltage Regulator Full Wave Rectifier. No additional hardware or wiring is included.
