What he said..........

 

dumb advice here to isolate the issue to the radio or the wiring.

unplug the radio, replace the fuse, turn ignition on.

fuse still good? then your radio is the problem
fuse still blows? then your wiring is the issue

 

good advice, i will defently do this.

 

how do i know witch wires to check with the voltmeter?
when i unplug the radio to see it the fuse still blows,if it does, do i then proge the wire in the radio plug and ground the othe end of the voltmeter?

thanks for the help, i feel like i will find the problem now.

 

the accessory connector under the seat is also connected to this fuse. make sure it's not gounding out there. easy checks before you start chasing down wiring.

 

thats a great tip, because i have a corbin seat and i take it on and off alot, maybe i pinched something, as a matter of fact i dont remember seing it around latly maybe it slipped down and is touching something. thank you!

 

I had a similar issue. Turned out it was the wiring harness in the fairing. There are two metal uprights on either side of the fairing, the one on the brake side was wearing through the wires as they came out of the harness housing. Taped them up. Fixed. Good luck.

 

Similar issue. Did not see the wire sheathing worn away but I notices there was a small arcing pattern on the metal frame. When I turned the wires around I found the bare wire.

 

Willie...if you are blowing a 15 amp fuse, you can bet your *** that you have a direct short to ground. The positive voltage line is touching ground potential somewhere. It's possible that short is inside the radio...but I would doubt it. Do check your battery terminals for cleanliness and correct torque. Is the voltage gauge in the faring reading normally? Good luck finding that short.

 

If it just started happening after you changed the battery, check all the wiring and harnesses near the battery. Chances are you disturbed a wire or harness somewhere and now it's shorting out. As the previous posters mentioned, check for insulation chaffing to the frame or brackets. Follow the wires as far as you can as maybe you pulled one too tight somewhere "down the line."
