Horn: Description and Operation

Voltage is applied at all times through Fuse C-20 to the coil and contacts of the Horn Relay. When either HORN SWITCH is closed, the Horn Relay coil is grounded, the relay is energized, and voltage is applied to both HORNS through the closed relay contacts. Since both HORNS are case grounded, the HORNS will continue to sound as long as either HORN SWITCH is pressed.
