1990 gk76a - horn not working

[Grey400]

Hi

My horn on my '90 gk76a has stopped working. I noticed before it would work sometimes and this was due to the connectors coming loose on the actual horn over bumpy roads.

Now its stopped altogether and it doesn't appear to be these connectors. I have taken them off, put them on again and generally fiddled with them to get the horn working but all to no avail.

I want to check the fuse - can someone tell me where this is?

I had wiggled the wires before and it started working but now no amount of wiggling wires will bring it back to life. Sounds like a loose connection somewhere but I can't find it

Anyone faced a similar problem?

The fuses are under the riders seat, my horn keeps disconecting too.

Thanks, I'll take a look. Do you know if the horn has a separate fuse? Sometimes they are on the same connection as indicators, lights, etc so if its the fuse then these go as well.
In my case, its just the horn.

Was talking to someone who reckons it could be the nut in the middle of the horn which may need loosening/tightening.

Its not due til next year but obviously the horn has to work for the MOT.

Fixed it
It was the screw in the centre of the horn. This tightens itself up to the point where the horn cannot vibrate and create the noise.
I guess this must be a common problem and happens when you press the horn and general movement with the bike. I was convinced it was the fuse or wiring.
