15 amp light fuse blowing
my lights were out,found the 15 amp light fuse blown.changed it was ok until I hit the high beams pop went the fuse again.went home took the fairging and the switch apart checked things could find any bare wires put the fairing back changed the fuse and it worked.than I put the switch back on the handle bars started her up checked it again and the fuse blew.I wondering if something is pinching in the switch harness when its reinstalled or only somehow when the engine is on it blows.any one have a simular problem.thanks in advance.

RE: 15 amp light fuse blowing
My money is on a pinched wire in the left switch housing. You may have to pull back the black plastic/rubber conduit to see it after you seperate the switch housing halves. The hi-lo wires are probably the yellow, blue, or white colored wires--they are on my '04 EG, and the colors are pretty standard year to year.

RE: 15 amp light fuse blowing
I'm not blowing the fuse anymore, nor did I completely identify the problem. I noticed that the switch housing wire cluster looked rather "crunched" inside of the clutch perch mount. I removed both of them, re-ran the wires through the clutch bar clamp, and the problem was solved. I'm sure that there is a quite possibly a bare wire portion somewhere in there, but I was too anxious to get back on the road with my new bike. Good Luck

RE: 15 amp light fuse blowing
one quick observation from previous experience.
Electrical current is like water...they will both find the path of least resistance.
Thus if you have a pinched wire...one that is not bare or shorted out...that will still likely blow a fuse.
Here is why!
If a wire is pinched, the flow of current is restricted and causes the wire to over heat (for lack of a better term)
This over heating produces a strain on the wire and the circuit. The fuse, which is the path of least resistance, blows because of the strain.
Eliminating the pinch in the wire will likely eliminate the restricted flow of current, which makes the curcuit no over heat and no more blown fuse.
Think of it sort of like kinking a water hose. The more you kink the more water pressure you get but the less water you get. Same principle with electricity.
