Turn Lamps

With the ignition Switch in RUN, BULB TEST or START. voltage is applied through the TURN Fuse and the Turn/Hazard Flasher to the normally closed contact of the Hazard Switch in the Turn/Hazard-Headlamp Switch Assembly.

With the Turn Switch in the LEFT position, voltage is applied to both the LH Turn Indicator and the LH front Park/Turn Lamp. Voltage is also applied to the LH rear Turn Lamp. The Lamps go on immediately and begin to flash as the Turn/Hazard Flasher opens and closes the circuit. The turn lamps will flash at 2 times the normal rate if a bulb is in need of being replaced.

The voltage applied to the LH front Park/Turn Lamp will also be applied to the LH front Marker Lamp. If the Headlamp Switch is OFF, the LH front Marker Lamp will find a path to ground through the RH front Marker Lamp, RH Turn Indicator and RH and LH front Park/Turn Lamps. These lamps provide low resistance paths to ground. The LH front Marker Lamp will flash with the Turn Lamps. The Lamps used for the ground path will not flash. because the voltage drop across the Marker Lamp is much higher than that across the other lamps.

When the Headlamp Switch is in either PARK or HEAD, voltage is applied to the Marker and Park lamps. If the Turn Switch is in LEFT, the LH Marker lamp will have voltage at both connections and will not light. When the Turn Flasher stops voltage to the Turn lamp, the Marker Lamp will be grounded through the Turn Lamp. and it will light In this way, the LH front Marker Lamp will flash on when the turn filament of the LH front Park/Turn Lamp goes off. and off when the turn filament of this lamp goes on.

With the Turn Switch in RIGHT voltage is applied to the RH lamps in a similar way.
