Turn Signal Lamps

With the Ignition Switch in Run or Start, voltage is supplied through the TURN B/U Fuse and Tarn Signal Lamp Flasher to the normally closed contact of the Hazard Switch to the Tarn Signal Switch.

With the Turn Signal Switch in LH turn position, voltage is supplied to LH Front Park and Turn Signal Lamp by the LT BLU (14) wire, Voltage is supplied to the RH Front Park and Tarn Signal Lamp be the DK BLU (15) wire. Voltage is supplied to the LH Rear Park and Turn Signal Lamp(s) by the YEL (18) wire. Voltage is supplied to the RH Rear Park and Tarn Signal Lamp(s) by the DK GRN (19) and the YEL (18) wire (Utility Only).

The Lamps go on immediately. They begin to flash when the current flow heats up the timing element in the flasher and it repeatedly opens and closes the circuit.

The voltage supplied to the LH Front Park and Turn Signal Lamp will also be supplied to the LH Front Side Marker Lamp. If the Headlamp Switch and Panel Dimmer Switch are in the Off position, the LH Front Side Marker Lamp will find a path to ground through splice S133 and the other lamps connected in parallel to ground. These Lamps provide low resistance paths to ground. The Side Marker Lamp will flash with the Turn Signal Lamp. The lamps used for the ground path will not flash, however, since the voltage drop across the Side Marker Lamp is much higher than that across the other lamps.

When the Headlamp Switch is in either Park or Head, voltage is supplied through the PRK LPS Fuse, Headlamp Switch and Splice S133 to the Side Marker and Park Lamps. If the Turn/Hazard Switch is in TURN LEFT, the LH Front Marker Lamp will have voltage at both connections and will go out. When the flasher removes voltage to the Turn Lamp, the Marker Lamp will be grounded through the Turn Lamp and will go on. In this way, the LH Front Marker Lamp will flash on when the LH Front Park/Turn lamp goes off, and off when the Tarn Lamp goes on.
