Horn on my 72 just quit working.

When I short the horn button to ground at the (#5) post on the relay, assuming that black wire is ground and I press the horn, the KEY BUZZER sounds... :-(:banghead:

QUOTE=67Dart273;1969785511]It's most likely a bad horn button, or bad connection. Short the horn button wire to ground at the relay and see if it works. Then go up to the harness connector under the column and probe the column connector and ground the wire there.[/QUOTE]
