Wiring without a Horn
« on: May 18, 2008, 01:16:35 PM »
So my bike left me stranded on the freeway the other day, in the carpool lane overpass, 3 stories above the rest of the traffic. After 2 hours in the sun, having traffic on the freeway below me stopped (because the CHP thought I was going to jump) and a $50 tow from Choppertow, it turned out to be a blown fuse ($.50). Once I changed the fuse all was good, it fired right up. A couple of weeks later the fuse blew again (this time it was at start-up) Replace the fuse and... pop. Everytime I turn the key the fuse blows! After hours of trying to figure out what was shorting out, I found it. The Horn! If I disconnect the horn all is good.

So here is my question: If I am going to run my bike without a horn, what do I do with the loose wires? Should I terminate them or connect them together?

Thanks in advance for all your help!

Are you sure it's the horn and not just a coincidence?  If you haven't actually found the short, I'd keep looking until you do.  If you have a multimeter, try checking for continuity where there should/shouldn't be any.  If you don't have a multimeter, pull the control off the handlebar and look for damaged wires, etc. 

IIRC, the horn end are the male connectors and the harness side has the female connectors which are insulated.  So, just unplug and enjoy the silence.  You could pull your horn off if you're not going to use it.

Good Luck!

Your problem makes some sense if the horn has a short, or at least a short starting.  Sometimes a short starts out slow by just causing some resistance, or an occasional touch to ground.  And it is wired so the power(12v+) comes in from the fusebox, and the other wire goes to the handlebar switch to get a ground.  So a short in the horn is a distinct possibility.

Thanks for all the help. I have been running without the horn and all is fine, I just terminated the loose ends. I am now in search of a good horn.

Thanks again

Buy a Fiamm horn. It scares the $%#! out of drivers who are trying to cut you off.  ;)
