Finished my YZF600 front end swap on my 1985 1100 and was checking everything out, and my horn didn't work.(worked before)
I found out that if I turn the bars slightly to the right the horn will work. I have pulled on all the wiring while pressing the horn to see if I
can find the offending wire. No luck. I set the fairing in place to see if not having all the plugs connected would make a difference
and still the same outcome. I did find that I have two extra wires at the headlight plug that are not used, and I can't find any wires not plugged
in. One is blue with red or pink. the other is two black together. Both have female bullet ends. I don't remember if I unplugged these two wires
when I took the faring off, or are they just not used. Don't know if it has any
correlation to the horn. Anyone have a suggested? I added a of pictures of the extra wires.
Thanks, John K

G'day John, on my '85 those two wires next to the headlight plug, connect to the parking light bulb inside the headlight. In the US, I think you call it a running light. Sounds like the horn switch may not be grounding properly. The horn has positive power connected and relies on the horn switch to ground the circuit. Pete.
I went out and looked and didn't find any extra plugs on the cluster or at the turn signals.
I was just re-working the headlight wiring on my '85 last night. I also have those 2 female bullet connectors hanging off of the headlight plug harness. They're not connected to anything.

Thanks! That solves one mystery. Now to find out why the horn is acting up.
I think that I may be able to shed some light on the 2 extra wires. (Pun Intended). The extra wires should be Blue w/Red stripe wire and a solid Black wire. These are used on the UK designated bikes for the Parking Light circuit.
Maybe we can get some of our UK friends the chime in.

thats what's connected to my parking light
just a thought on the horn issue, Can you take a piece of wire to make a temp ground wire, Hook it up to your horn and ground it some where, see if your horn works?, If so, Replace the ground
I'll try that this Saturday.
