Full Wave Single Phase 4 Pin Regulator Rectifier Unit

Is This the Right Unit for Your Bike?

To determine whether the stator in your motor is full wave or half wave, you can check both the wire colors and run a simple continuity test.

✅ Full Wave Stator:

• Typical wiring: Two yellow wires, or one yellow and one pink wire coming from the stator.
• Continuity test: The yellow and pink/yellow wires have continuity with each other, but no continuity to the engine block.
• Use this full wave regulator rectifier.

⚠️ Half Wave Stator:

• Typical wiring: One yellow and one white wire from the stator.
• Continuity test: Both wires show continuity to the engine block (0 ohms or close to it).
• Do not use this unit—you’ll need a half wave regulator rectifier instead.

Please check the wiring diagram in the product photos for further guidance and clarity on how the system works.
