Hazard Warning Lamps: Description and Operation
Circuit DescriptionHazard 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.
