Motorcycle tail light keep blowing fuse?

I have a 1999 Suzuki GSX 750 F which is in pretty good condition... for some reason the tail light fuse keeps blowing (and also when this goes the instrument panel lights do too - I assume they're on the same circuit) When I change tail light fuse, the tail light and instrument panel backlight come back on... this doesn't affect the head light, which works fine, or the brake light which also is fine...any ideas why the tail light fuse keeps blowing... and how can I fix it?

Got to be a short to earth somewhere either the panel lights or the tail light,try the tail light first try moving wires about with ignition on and a new fuse in and see if it blows,then try the other way with the panel lights,all a process of elimination.

You're in for some trial and error. Assuming you're using the correct fuse(should be 15 amp I think), there's gotta be some point in the wiring where it's most likely pinched and grounding out.



Does it have a any type of eliminator kit? A lot of people accidentally pinch wires installing those. If so, I'd check the wiring where the work for that was done. If there is no eliminator kit, or you still didn't locate the problem within the kit work..... Then you've really only got two options, both are unfortunately tedious and boring.



You could remove the light assemblies and see if it still blows. If not, put them back one at a time and see which specific part is triggering it... Or, it's time to just bite the bullet and trace all the wires for a grounded point.
You may have a short somewhere. I would check the wires carefully under the seat, it could be pitching by the seat or fuel tank.
Hi there, It sounds like one of the cables is shorting out, the probable cause is a wire that passes close or rests on a piece of metal (frame or bolt) and the outer plastic covering has slowly worn away exposing the wires inside. I had a wire like that and it drove me to distraction trying to trace the fault. Separate each wire from the light and slowly and methodically check all round the wire back to the next connection. Good luck.
