What are the yellow & white input wires into voltage regulator on 110cc Honda XRM 2?
If you unplug the stator wires (yellow & white), will the headlights turn on? If so, run both of those wires to the regulator/rectifier. The only bikes that run the headlights with the stator wires, are off road bikes “without” batterys. This is the first time I’ve ever seen an XRM110, as they weren’t sold in my area. Put a volt meter on the battery and rev the engine. If the voltage doesn’t increase, the stator is probably shorted to ground. The yellow & white wires shouldn’t touch ground (with 3 phase charging systems they don’t. I’m not 100 percent sure with your model. Consult a servire manual). That’s probably why one wire is only putting out 12Vac. The other 2 wires you are talking about go to the CDI box, which sends power to the coil when it’s time to fire.
