Horn not functioning

I have a 72 that I'm currently restoring and my horn is not functioning. I have no power to the green wire that goes to the horn when you press the button on the steering wheel. Has anybody had this issue or maybe know of a flow chart of where to start testing to determine the problem?

Have you checked the horn relay? I had the same issue with my 72. I disassembled the horn relay, cleaned the contacts and the horn started working. I verified that the horn was good by running 12 volts directly to the horn.

Here is the troubleshooting guide I used to solve my horn issues. It's easy to follow and understand.

Mine on my 81 miraculously started working after replacing the rag joint... Just sayin

Dunno if that makes it ground related... Or just jostling the column around helped it out...

The ragjoint provides 'ground' for the horn electrical needs; +12vdc power is supplied by the horn relay and wiring to the horn button/switch.
