Turn Signals: Description and Operation

Circuit Description

Turn Signal Lamps Operation
With the hazard switch in OFF and the ignition switch on ON or START, battery voltage is supplied from fuse 1 to the flasher unit. The solid-state in the flasher unit senses the turn signal switch position and alternately applies and removes battery voltage to the turn signal lamps through the coil in the flasher unit controls. Voltage is applied to the left or right turn signal lamp and indicators dependent upon the turn signal switch position.

Hazard Lamps Operation
With the hazard switch depressed (ON), battery voltage is supplied from fuse 4 to the flasher unit. The solid-state in the flasher unit senses the hazard switch ON signal and controls the relay coils, and then alternately applies and removes battery voltage to the left turn and right turn lamps and both indicators at the same time.
