Gl1500 blows fuse

Postby rbehrens » Sun Jun 21, 2015 3:40 pm



1988 gl1500 blows horn blinker fuse while riding without using turns horn or brakes. Replace and it would go a few miles then blow again. Now blows as soon as I start it. This is without using the turn signals horn or brake lights.

The white wire/green stripe is the main feeder wire which supplies the horn/brake lamp circuit. It is fused at the main box and runs to the horn switch and both brake lamp switches, so it covers a lot of territory. If it's blowing fuses without closing either switch, the problem is somewhere in that wire. It's pinched or something it's connected to is grounded. You can eliminate the horn switch by unplugging it inside the headlamp bucket. A good visual inspection is probably the best next step.

Yes, you definitely have a short somewhere, the first thing you'll need to do is start disconnecting connectors and try to isolate the portion of the harness at which the short is occurring. Shorts don't usually happen inside the harness unless a wire has physically melted, or has been subject to outside interference (i.e. rodent chewing). Particularly for wires that run to handlebar switches, it's often a wire that has been routed incorrectly, or has been pinched by handlebar movement.

Ok. This one is hard to believe. Was having short problem and engine stopping. Thanks to the responders I was on the right track looking for a short. Took panels off and spent a long time tracing wires down. Ended up at my left hand controls. Specifically my horn button. Took the two screws out of bottom and opened controls. In the bottom half I found a screw the same as the short one that holds it together. Just floating around in there. I think someone working on it lost the screw.and didn't see it there so got a new screw and put things back together. 2 years ago I blew my horn and the engine died. Replaced the horn fuse snd didn't think too much about it. The screw must have gotten jambed and has been ok till a few days ago I was on a very bumpy driveway. The screw must have come loose and started shorting out under there. The screw has signs of shorting on it. Discoloration and a little pitting. Put all back together and problem solved. Things aren't always what they seem. Glad to be back on the road.
