Horn: Description and Operation

HORNS SYSTEM DESCRIPTION AND OPERATION

SYSTEM DESCRIPTION
The horn system consists of the following components:
- The HORN fuse
- The horn relay
- The horn brush slip ring
- The horn switch
- The horns

SYSTEM OPERATION
The vehicle horns are activated whenever the horn switch is depressed.

CIRCUIT OPERATION
Battery positive voltage is applied at all times to the horn relay coil and the horn relay switch. Pressing the horn switch applies ground to the horn relay control circuit. When the horn relay control circuit is grounded, the horn relay is energized and battery positive voltage is applied to the horns through the horn control circuit. The horns sound as long as ground is applied to the horn relay control circuit.
