My Spit failed it's MOT test on a knackered horn, all it was was the coupling
at the bottom of the column hadn't got an earth wire running through it, I just
had to connect a piece of wire 'over' the coupling using the pinch bolts and
voila - a horn....well, the girlfriend was impressed anyway!!! :-)
Before, the horn would work but only with the ignition off, and then I was
getting a small shock off the steering wheel spokes as it was somehow using
these(and me!!) as an earth.
Good Luck
