     Recently started having the horn fuse blow out of the blue. I have replaced it half a dozen times in the last 10 days. Somtimes it will last all day and other times only a few minutes. Only reason I knew the fuse blew is because I power my sirius radio off the 12 volt outlet in the glovebox witch is evidently on the same circuit. Tried un plugging the sirius radio and still the fuse blows with no load on circuit. I can blow the horn all day and no problem then randomly the fuse will blow and then no horn.

     Help.....paulhu

Do you have a GPS? And if you do do you have it connected? If it is not connected do you have the plastic boot on the bare connector to prevent it from shorting out?

      No GPS, I assume the connector is located under the radio cover.? What does the GPS connector look like? Is it on the same circuit as the horn?

Thanks for the reply, paulhu

If no GPS you dont have to worry about it.

If you've had the side skins off recently you may want to check and see if a Badge light wire got pinched during reassembly.

Say when I hooked up my electric vest I found a connector under the dash that was not being used for any thing. Look for one. I all so noticed victory connectors have a black dot over the power side of connectors.
I haven't had any problems with my vest

I had a vision blowing the same fuse. Check to make sure nothing has fallen into any of the power outlets. It can short it out and blow fuses. My instance was that the rider carried bearing balls in his glove box. The cap came off of the outlet and a bearing fell in.

       In following the schematic varyder posted I found a small white plastic wire connector under the radio which has a spade type plug in one end. I believe the wire was brown/pink. Anyhoo, the shoulder of the spade connector protrudes slightly out of the end of the white wire connector and appeared to be shorting on the handlebar mounting bolt on the right side. I tried inserting the spade end further into the plastic comnnector to no avail, so I just wrapped the entire assy. with electrical tape and no problem since. It was a shot in the dark as I didnt try to fail the circuit manually by shorting to the bolt (should have in hind sight) but all attempts to recreate by riding lots have not reproduced the problem so I think I got lucky. It was shorting on every ride for a week or so and now I have ridden two solid weeks with no more fuse changing.

       Thanks for all the great imput from everyone and a special thanks to varyder for posting the wiring diagram.

From the location and wire color you describe I am guessing it is one of the positive feeds for the lighted badges. If you don't have them, that is where one of them would have plugged into. If you do have them. I'm guessing one ain't so bright now.

    According to the schematic above, the badge lighting circuit would be interrupted by the short up current of the badge bulbs, blowing the fuse and not harming the lighted element. My badges are fine, thanks.
