Turn Signals: Description and Operation

The turn lamps can only be activated with the ignition switch in the ON or START position. When the turn signal switch is placed in a position to indicate a left turn or a right turn, the respective turn signal lamps will flash. The respective turn signal indicator will also flash on the Instrument Cluster (IPC).

With the ignition switch in the RUN position, battery positive voltage is provided from the TURN Fuse, and through the turn signal flasher to the normally closed turn/hazard switch.

When the turn signal switch is placed in the LEFT TURN or the RIGHT TURN position, battery positive voltage is supplied through the turn signal switch and to the turn signal lamps. They begin to flash when the current heats up the timing element in the flasher and opens the switch. The turn signal flasher switch closes when the timing element cools. The flasher repeatedly opens and closes the circuit causing the turn lamps to flash. Battery positive voltage is applied from the HAZARD Fuse through the hazard flasher to the normally open turn/hazard switch. With the hazard switch in the HAZARD position, battery positive voltage is applied through the turn/hazard switch assembly to all four paths used by both front and rear turn lamps. All turn lamps and both indicators flash on and off. When in the HAZARD position, the turn signal circuit is opened within the turn/hazard switch and the flasher controls the lamps even if a turn has been indicated.
