Default Strange problem

Anyone else have this problem?

When I turn on the high beam, the high beam light comes on, but so does the oil light... wtf? Oil light has never come on, in fact I just changed the oil yesterday, and that's when I noticed the problem as I was checking all of the lights.

I wonder if this has anything to do with why I keep blowing fuses???

15 amp fuse (tail light, turn signals & meter). I have no idea what the meter is, from what others are saying, possibly the rectifier?

In any case, I have no idea why it keeps blowing. I'm looking for a replacement rectifier now, but I'm not sure that will solve the oil/high beam indicator issue.

Any guesses?

I don't think it would be the rectifier causing the 15 amp fuse to blow. The rectifier is powered from the main circuit which carries a 30 amp fuse. The 15 amp fuse that you are having trouble with is more of a general distribution circuit and feeds the following: temperature gauge, speedometer, speed sensor, neutral lamp, oil pressure lamp, side stand lamp, horn switch/horn, turn signal switch/turn signals, turn signal relay, instrument panel lights, front brake switch, rear brake switch, brake light, tail light and license plate light. As you can see the short could be most anywhere. Problems like this are normally caused by someone making modifications to the bike and not properly insulating the circuit afterward. For example, different undertail added with aftermarket tail lights/signals, side stand switch defeated, aftermarket signal lights added, etc. I would start with any connection that has tape on it, has been spliced, or looks like something other than a factory connection. If you see any suspicious connections, take them apart and make sure all wires are connected properly, are insulated from each other and are insulated from any metal object. I have also seen where the insulation from a wire has become compromised where it has rubbed against the frame or a hard object.

Since you are seeing the oil light come on when you turn on the high beam, I would start with that end of the wire harness.
