I found the problem. The live wire from the horns connects to a spade connector on the underside of the steering wheel. The spade connector had come free from where ever it should have been fixed, so was flopping about, shorting against anything eathed & sounding the horn. I fished the wire out & it's now taped to the wheel boss. The first service is due shortly, when a new steering wheel is due to be fitted, so it can wait 'til then.
Nothing like 'sounding off' occasionally to get yourself noticed Ian. Enjoy the effect. joy
I'm used to being noticed in the Morgan. Just don't normally have to sound the horn to achieve it
