Horn blares when turning key on

bwader · 07-11-2018, 04:45 PM

All I did electrically was unhook the wire harness to access adjusting the valves.

So does it mean I need a new horn? It's funny I had the bike running before and didn't hit the horn button

You don't need a new horn because this one works. Just double check your wiring hook-up. I'm not sure but the horn may be activated by pushing the button to ground it. If so you may have accidently grounded it so it will blow all the time. It will be something simple so don't get excited about it. Pull a wire off the horn in the mean time if you need to ride.

Thanks. Yeah I tried removing either and both horn connections and horn doesn't blow. But bike work turn over. Green neutral light on.
I might make a video later.
Makes sense , horn must be grounded to blare all the time.
I'll have to try the horn switch maybe it got stuck somehow.

Don't think it's the horn switch. It was ok before you disconnected the harness, so it seems like a problem with the disconnection/ reconnection.

I took apart the switch. And a lot of little parts. Sprayed electronic contact cleaner.
Same issue. So I'll try cleaning the connections on harness when I get off work

Switch has continuity on both wires to it and from either wire to button contact point.

Now to order a replacement.
It's just a little button
