Last year I noticed that one of the wires from the hi/lo switch was frayed and not making contact. I replaced the switch with a good one and now I have no headlight. Taillight works fine. I checked all the wiring in the entire harness!! I am wondering if the voltage regulator can fail in such a way that it only affects the healight? Anyone have an idea?  |

Do you have a circuit tester to see if you have voltage to the light socket?

I accidentally had my voltmeter set to AC volts and I got a reading of 10 volts AC from the light socket. When I set it DC volts, then I got nothing. I feel like it could be the regulator, but why does the taillight work just fine?? Wierd  |

I feel like it could be the regulator, but why does the taillight work just fine?? Wierd try a test light and see if it will light it at the headlight. Sleds actually produce AC, I do believe. A rectifier or in some cases the voltage regulator will turn it into DC where needed. When I was researching LED lights, that was the info I got from others, anyway. 10 volts would probably be what you could expect for voltage at idle. You can also check the bulb pretty easily by connecting it any 12V battery. If the voltage regulator goes out, lights may still work, but they have a tendency to burn out very quickly. As may other electrical components  To be honest, I don't see many of the later voltage regulators go bad. The 75's did use a different regulator though I think. Not sure about those. Make sure the bulb is good, then check your voltage at the light. If both test good, make sure you test the ground wire from the harness as well. Just connect the test light ground to it rather than just grounding the test light to the chassis. That will test the complete circuit the bulb sees. |

Ok, I solved the lighting problem. I was using a bulb that was burned out to test........I hate it when it's the simple stuff...oh well  |
