Before you go tearing things apart, disconnect the two wires that come out by the steering box. One is the light blinker switch, (black ring) the other the horn. If the horn wire is shorted to GROUND, the horn will... well beep. You can check the condition of the horn button and wire with an ohmmeter. If it still sounds with the wire disconnected, your short to ground is between there and the relay. Disconnect the horn wire at the relay. Should be QUIET. Also will indicate the short to ground is between the steering box and relay.
Only once did this happen to me on re assembly of a restored car. I had pulled the horn button wire out of the horn button switch asccidently, when I "adjusted" the position of the wires at the steering box to run them under the hold down clip. The loose horn wire at the top of the column shorted to the column. Hope this helps. Gordon Raymond
