System Description
The horn system consists of the following components:
| • | HORNS circuit breaker |
| • | Horn relay |
| • | Horn switch |
| • | Horn(s) |
System Operation
The vehicle horn system is 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 horn(s) through the horn control circuit. The horn sounds as long as ground is applied to the horn relay control circuit.
