Been doing a few MOT checks before Wednesday on my old 306. I thought it was the horn button on the stalk which was broke, but I've shorted out the switch and still no workee, so I either have to fix the horn itself, or retrofit something. The horn is located in the depths of the front wing, and requires much work and dirtiness to access (drilling rivets etc).
Much easier I think to buy a new one (maybe plug into cigarette lighter?) and have a switch on the dash. This only has to be a temporary solution. Do you think the MOT people will accept it? Super cheap solution would be an aerosol/pump-up air horn like you get for bikes. Or, less cheap, a massive truck-style air horn with it's own compressor…
Thoughts?
Cheers
