Alfa Romeo Repair: Alfa Horn Repair, alfa spider, horn buttons

Question
The horn on my '82 Alfa Spider just went kaput. Just up and quit one day. Horn buttons on steering wheel seem to work, and I checked fuses and wiring, but can't figure it out on my own.

Got a wiring diagram or suggestion?

Many Thanks

'82 Spider


Answer
Put test light on positive lead at horn and other end on ground. push horn button. If the tester lights up then check
the horn ground by connecting test light to positive lead of
battery and body of horn. If it lights up, the horn itself
needs replacing. If the tester does not light up when
testing the postive side you have a relay, a fuse and
the wires and contacts under the steering wheel to test in
the same fashion.
