Turn Signals: Description and Operation

Turn Signals
Power for the turn signals flows from the Power Distribution Center (PDC)to the ignition switch on circuit A1. The A1 circuit is protected by a 20 Amp fuse located in cavity A of the PDC. With the key in the ACCESSORY or RUN position, the ignition witch connects voltage from the A1 circuit to the A31 circuit.

Circuit A31 connects to the junction block and powers fuse 3. This is a 10 Amp fuse. From the fuse, circuit L5 supplies voltage to the turn signal switch. Circuit L55 connects between the turn signal switch and the combo flasher. This circuit is connected to circuit L5 internal to the switch and provides voltage to the combo flasher.

The L32 circuit connects between the combination flasher and the turn signal portion of the multi-function switch. Circuit L32 connects to a BUS bar internal to the switch that powers the turn signals and the hazard flasher.

Right Turn Signal
When the operator selects the right turn signal, the multi-function switch connects power from circuit L32 to circuit L60. Circuit L60 supplies power for the front and rear turn signal lamps. This circuit also splices and supplies power to the instrument cluster indicator lamp.

Ground for the rear lamps is provided on circuit Z1 and terminates at the left rear wheel well. The ground for the front lamp(s) is provided on circuit Z1 and terminates at the right headlamp ground located at the right front frame rail.

Left Turn Signal
When the operator selects the left turn signal, the multi-function switch connects power from circuit L32 to circuit L61. Circuit L61 supplies power for the front and rear turn signal lamps. This circuit also splices and supplies power to the instrument cluster indicator lamp.

Ground for the rear lamps is provided on circuit Z1 and terminates at the left rear wheel well. The ground for the front lamp(s) is provided on circuit Z1 and terminates at the left headlamp ground located at the left front frame rail.
