Horn: Description and Operation
NOTE: The following information is intended to be used in conjunction with the electrical diagrams.CIRCUIT OPERATION
The horn system uses two switches and a horn relay. The horn switches are in the steering wheel along with the speed control switches (if equipped).
Circuit A3 from fuse G in the Power Distribution Center (PDC) feeds a fuse block bus bar that powers circuit X1 through fuse 6. Circuit X1 is HOT at all times and powers the coil and contact sides of the horn relay
When the horn switch is depressed, circuit X3 provides ground for the coil side of the relay and the contacts close. When the contacts close, circuit X2 supplies voltage to the horn.
