A couple of days ago I drove my bike, stopped to fill up for gas, and then it would not start. Everything was dead - as if the battery was dead. The battery was good, though, so I checked the fuses, took a summary look for any shorts in the wiring, and jiggled everything I could get my hands on without taking the whole bike apart.

Initially the best I could get was some power (so that the neutral light lit), but when I tried to engage the engine I'd hear a "click" from under the gas tank and everything would go dead again. I eventually got it running (just enough jiggling, I guess), although the turn signals would not work and the gauge lights would not work (no hi-beam light, no neutral light...). And when I engaged the turn signals the tach would drop to zero - otherwise it and the speedometer worked fine. It was suggested to me that there must a poor ground connection or some other intermittent short in the electrical system.

I didn't have the time nor the knowledge to fiddle with all that, and I really wanted the bike running and reliable for this weekend, so I took it to a guy who started going through all the electrical circuits looking for problems. At this time he says I need a "signal relay" (Nippon Denso part no. FU257, he says), a flasher relay (he does not know the part no.) and a "quadrant," whatever that is (I didn't understand his description).

Does any of this make sense, and if so, where can I find these parts? He's having trouble sourcing them.

I would check the fuses again. Make sure the fuses are making contact and the fuse wires are in good shape. So far, I have replaced two fuses from under the seat with square inline fuses. First, the last owner had a straight inline fuse already installed. The fuse lost contact and the Maxim lost all power. While trying to make the fuse have contact. The plastic tip of the inline fuse housing broke right off.

Then while checking the rest of the fuses. I noticed that one of them appeared to have good contact. But it didn't, so I put in another inline fuse. The fuse might look alright but it may not be getting good contact.


There are a few relays located under the tank. I had the rubber strap break with one of the relays. This allowed the relay to drop down onto the motor. Are the relays all in their original positions?

Would the relays make it so there is no power? I would try to figure out why it didn't have any power first. I'm not sure what he means by "quadrant".

A quadrant is a machine part that is shaped like a quarter circle.
