[DICK SPADARO]

No Don, these horns are not internal ground horns there are two wires hooked to the horn much like a regular lamp cord. One wire is the power the other is the ground, the circuit is completed when you push down on the horn rod. The power flows thru the horn when the button grounds and thus the horn beeps. Bruce from OH's issue is that his horn blows immediately when power is applied indicating that somewhere the circuit is grounded.
