Default Keep blowing fuses

About a month ago, I blew a fuse when I hit the start button. I replaced it and it worked fine. But now it is blowing that same fuse almost everytime I hit the start button. I took the switch off and it looked fine. The wires going to it were clean and not cut.


If I have a short somewhere, where should I look first? Could it be the starter going bad, or the solenoid going bad.?


It's really annoying going to start the bike and hearing the fuse pop.

My offer still stands... It will be very difficult to diagnose electrical problems like that through the forum. You should at least consult a wiring diagram to look for the possibilities of the problem. What conditions cause the fuse to blow? Meaning, does it blow when you flip the switch to ON or when you hit the starter switch. Does it happen immediately, or does it (starter motor) run for a few seconds before it blows.

You have already verified the connections are clean, you need to get a digital multi meter and check the wires back from your start switch to determine which wire has a short. Remove the + wire from the battery and set the multi meter to Ohms, check each wire to find the shorted one.

Put in a new fuse, and remove the starter relay. Hit the starter button again and if it blows the fuse, you've got a stretch of wire that is shorted to ground somewhere between the output side of the start switch and the input side of the starter reley socket.

If it doesn't blow the fuse, pull the sytem relay, put it in the starter relay socket and hit the button again. If it cranks the engine and doesn't blow the fuse, buy a new starter relay and you're golden. Might as well get two, they are kind of a high failure item.

With out the sytem relay in place the engine won't start, but you can at least see if the starter relay is causing the short.

One other thing, you didn't specify which fuse, I'm assuming it is the "ignition" fuse.
