Re: Fixing a Horn 67 - Back again
Horn(s) get power from the relay under the voltage regulator on the drvr side of the radiator support, just to the left of the radiator.
The black wire in column is the key to energizing the relay, horn power is green wires.
Horn relay has a buss bar on it connecting the battery and electrical system together.
Relay coil gets power from the connection internally.
The black wire coming out to column should have battery voltage on it, until it touches ground, complete the circuit, relay closes, horn(s) blare.
PO may have wired horns directly with under dash button and pulled power from fuse panel spade and jumpered around the horn relay.
