XR125L Lightning problem

[Koos Louw]

I have a 2014 XR125L Honda.Only the brake light is working plus neutral. The neutral light has it's own positive wire. I have replaced the regulator, and still no lights except brake light are working. There are 4 wires on the regulator. Green, yellow, white and red. Red has positive, green has negative, white has power from magnito, yellow does not supply power to the lights. All fuses are working properly, all wires continuity test back to front is correct. Ground wire tested from inside magnito to body plus regulator to lights ok. Already spend a lot of money on regulator, please help!

Have you just bought the bike? On many small Hondas, lights are powered directly from the generator, so engine has to be running for lights to work. Only brake light, dash lights and horn work from battery.

Thanks for reply. You are correct about starting before lights could work. When you start the bike there is power supply (white wire) from the generator but that supply go straight to the regulator. There is a red wire supply battery positive power, and a green wire supply ground. Then the fourth wire (yellow) on the regulator needs to supply the power to the lights but receive no power. I tested both regulators on other bike and both are working. I hope you can help me. Thank you

First you need a wiring diagram, either off line, or from a workshop manual. I ask again, have you just bought this bike, possibly with the fault already on it ? On bikes with "direct" lighting, like this one, the power for the lights comes directly from the generator [alternator], and not through the regulator. I think somehow you have wires not connected correctly, or possibly, a faulty coil in the alternator. You need a diagram.
