So today I went out everything was fine. After a while I looked down and My speedometer read 0. Also the mileage display was blank. I pressed the button and the mileage would come up for a few seconds then go off.

Then I noticed that neither turn signal would work, on the display, or the actual signal. On the display Neutral and the oil light still worked.

It wasn't till I got home that I noticed the Headlight did not work as well.

The whole time I had no drivability issues.
The battery is new.

Any Ideas?

 

Possible loose connection.

 

Other possibilities are a chafed wire grounding where it shouldn't, corrosion to a ground or in a connector. Chose one of those things not working at present and follow the wiring. Disconnect every connector you come across, clean and zap with a dialectic lubricant, ditto every ground. Clean and check for tightness your battery connectors. You just have to doggedly and patiently inspect.

These sorts of problem are usually mechanical. That is to say as Brion suggested, something loose or broken. Hopefully you will come across it pretty soon. Good luck!

 

Thanks guys, i checked the fuses and two were blown, replaced them and everything worked fine..for a few minutes of ride time. Now those two are blown out again, looks like I'm going to have to go wire hunting.

 

Have you changed bars or done any work to the bike recently?

 

No I Haven't done anything to the bike, though It has been modded.

 

Looks like it might be the headlight, or a wire coming from it. Trying to trace it now

 

So I pull the bulb out of the housing and there are 4 wires, 2 are black grounds, all of them are cut with butt connectors.

One ground has a terminal to the screw holding the base in, the other went to the wiring harness.

The one connector for the ground going to the harness was burnt up, bingo. So I replace it, pop a new fuse in and turn the ignition on. still nothing.

I check the fuse and its already blown.

I use my volt meter and check every connection from headlight bulb plug, to wiring harness plug under the gas tank. All come up positive.

What do I do from here?

 

Another update. I unplugged the connector under the gas tank for the headlight, and checked the wires from there to the fuse block. didn't see anything wrong. Put in a new fuse, turn the key, pop, fuse blown again with the headlight connector unplugged.

 

I would look at wiring from the left switch housing. Make sure nothing is pinched or cut. Mainly where the bar is dimpled.
