The horn on my Brava sounds whenever the front end of the car receives
a sharp jolt - for instance if I drop the bonnet or drive over a bump
in the road. I would like to have a go at fixing this myself rather
than pay a Fiat dealer a fortune to do so. Has anyone had a similar
problem, or can suggest how I approach the problem of tracing the
fault? Thanks.

On cars it is usual to have a switched earth rather than switched live.
It sounds like the earth wire from the horn has chafed and is shorting to
earth when it moves, causing the horn to sound. You'll have to trace back
the wres from the horn and see if there's any obvious damage.
