What are the yellow & white input wires into voltage regulator on 110cc Honda XRM '02?

Question

The 2002 Honda XRM has a wiring problem, miswired by the last owner. The voltage rectifier/regulator has a green wire (this I know is ground), red (this I know, goes to battery), yellow, and white. The stator does have a yellow and white output wire, one producing a max of about 12Vac, the other a max of about 20Vac, both apparently relative to ground [don't ask me why this stator is wired relative to ground. I see that the stator also has two other wires right now leading to some kind of electrical box linked to the spark plug coil, one high voltage, one low voltage. Should they both be connected to the voltage regulator? Or should one go to the front headlights also? or to front headlights only? Should there be a "12v Switched" wire from the ignition to the voltage regulator? Basically the main question is "where exactly should the yellow and white wires into the voltage regulator come from"?

Thanks!!

Thanks, more info.
As currently (mis?) wired, the stator has a yellow wire that goes to the front of the bike (lights?) AND to the voltage regulator. When the engine revs normal, voltage is 4V AC relative to ground/chassis on this yellow. Revving HIGH, the voltage goes up to 8-10V. So headlights come on (dim) only when the engine is revved high, and don't come on at all when yellow stator wire disconnected.

The stator has a white wire that goes to the voltage regulator only. This wire has 10-12V AC relative to chassis at low RPM, up to 16-20V AC at high RPM.

The output of the RED when I disconnect from battery wire is 4-6v DC relative to ground/chassis at idle, up to 12V at very high RPM. TOO LOW.

I bought a new voltage regulator & stator & battery. The same voltages still! Revving, the battery v does not go up. Only by measuring current can I see that revvin high the slight discharge ->slight charge.

I'm trying to locate manual but uncommon bike. Should it have a 12v sw wire?

Answer 1

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.

Answer 3

we want greater information on what precisely you're attempting to do. you probably can not use a voltage divider, till the element you're powering attracts a persevering with quantity of present day, and additionally you take care of the burden as R2. i'm very almost specific you like a real regulator.
