Lighting and Horns: Description and Operation

Voltage is present at the Main Light Switch at all times through Fuse 9 and circuit 195 (T/W).

With the Main Light Switch in PARK or HEAD, current flows through Fuse 9, the Main Light Switch and circuit 14 to the I/P Cigar Lighter Lamp, the Clock, the LCD Dimming Relay, the Electric Brake Controller Connector, the Trailer Exterior Lamps Relay and the exterior lamps. The I/P Cigar Lighter Lamp and the exterior lamps illuminate. The voltage applied to the Clock causes the Clock display to dim. The voltage applied to the LCD Dimming Relay energizes the Relay to dim the Radio LCD display. The voltage applied to the Trailer Exterior Lamps Relay energizes the Relay to power trailer running lamps.

Voltage can also be applied to circuit 14 (BR) through the Autolamp Dual Coil Relay to power these same components.

With the Main Light Switch in the HEAD position, voltage is applied to the Multi-Function Switch cornering switch contacts through the Main Light Switch and circuit 15 (R/Y).

Pivoting the Multi-Function Switch lever downward closes the cornering switch left turn contacts in the Multi-Function Switch. Current flows through the Main Light Switch, circuit 15 (R/Y), the Multi-Function Switch, circuit 379 (BR/W) and the Left Cornering Lamp. The Lamp illuminates until the turn is completed and the Multi-Function Switch lever returns to the center (neutral) position.

Operation of the Right Cornering Lamp is the same as operation of the Left Cornering Lamp, except that circuit 380 (P/Y) is used in place of circuit 379 (BR/W).
