Horn fused? - SV650.org

25-03-10, 10:22 PM

Does anyone know if the standard horn wiring is inline with a fuse or circuit breaker of some sort. Was looking over the wiring diagrams and found the right wires to setup my new horn and hooked the proper wires up to the multimeter (curvy svs - so black with blue tracer + and orange with green tracer -) When i pressed the button i heard a click rather similar to the noise a relay makes. I never got a reading because i was checking to see if there was an associated fuse in the fuse box and found nothing. Now when i check the wires they read between 0 and and about 0.8v just nominal readings.

Anything you can think of that could cause this?

Supplied by fuse No 4, 'signal', as you may know the horn is live when the ignition is on, it's operated by connecting its neutral.
Fuse 4 also supplies the brake lights, the tail light, the side light at the front, (referred to as the 'position light' by Suzuki), the clock lights and some of the warning lights - neutral light etc, so if any of those work it's not the fuse.

Sorted new fuse and its working great. Strange thing though, I have almost none of those other bits of that list other than the brake lights (im going naked and streety). The thing that was weird is with the fuse broken and out the brake light and tail light both work. Are you sure that is included in that fuse?

Either way problem solved. Cheers.

The horn is controlled by that fuse.
