Start button blowing fuse
Hey everyone. I need some help! I stopped for gas after running some errands around town and after I was done filling up I turned the key and hit the start button and nothing happened. No click, no dimming of the dash lights, no action of the starter motor. I tried turning the key on and off and even tried unsuccessfully to push start it. AFter a few minutes of this, I hit the button again and it started right up! I rode to my next stop and shut the motor off, then turned the key back on and tested it and the button was dead again, but after a few minutes it came alive again. A few hour later I went to ride it home and it started the first time.
Searching this site I found several references to cleaning the ignition switch, but it seems to be doing fine; the motor is not cutting out while riding. Today I took apart the start button, cleaned the contacts, put it back together. I tested it in my hand and the starter jumped, then put the whole thing back in the box on the handlebars and put everything back together. (FWIW I changed the headlight bulb and lubed the throttle cables as well.) But, when I turned
the key and hit the starter it did nothing again! Not only that, but I hit it a few more times then the main fuse blew. I changed the fuse and tried again and the fuse blew on the very first try. I've taken a continuity tester and determined that the start button is completing a circuit. I used a test light and tried various connections to see if they were live but when I touch it to the start button metal it not only lights up but a buzzing comes from the junction box as well. I also tried touching a screwdriver to the two posts on the starter solenoid to bypass it and power the starter; I got a great light show but no action from the starter. I checked the wiring around the steering neck and nothing looks pinched or damaged. Any suggestions would be greatly appreciated!
