TURN LIGHTS
With the Ignition Switch in "RUN," BULB TEST," or "START," voltage is applied through Fuse 5 and the Turn Flasher to the normally closed contact of the Hazard Switch in the Turn/Hazard Switch.

With the Turn Switch in the "LEFT" position, voltage is applied to both the LH Turn Indicator and the LH Front Park/Turn Light (CKT 14). Voltage is also applied to the LH Tail/Stop-Turn Light (CKT 18). The lights go "ON" immediately. They begin to flash when the current flow heats up the timing element in the Turn Flasher and it repeatedly opens and closes the circuit.

The voltage applied to the LH Front Park/Turn Light will also be applied to the LH Front Side Marker Light. if the Headlight Switch is "OFF," the LH Front Side Marker Light will find a path to ground through the RH Front Marker, RH Turn Indicator and LH Front Park/Turn Lights. These lights provide low resistance paths to ground. The LH Marker Light will flash with the Turn Lights. The lights used for the ground path will not flash, because the voltage drop across the Marker Light is much higher than that across the other lights.

When the Headlight Switch is in either "PARK" or "HEAD," voltage is applied through Fuse 7, the Light Switch, and to the Marker and Park Lights. If the Turn Switch is in "LEFT," the LH Front Side Marker Light will have voltage at both connections and will not light. When the Turn Flasher stops voltage to the Front Park/Turn Light, the Marker Light will be grounded through the Turn Light and will go "ON." In this way, the LH Front Side Marker Light will flash "ON" when the turn filaments of the LH Front Park/Turn Light goes "OFF," and "OFF" when the turn filaments of this light goes "ON."

With the Turn Switch in "RIGHT," voltage is applied to the RH lights in a similar way.

HAZARD LIGHTS
Voltage is applied at all times through Fuse 2 and the Hazard Flasher to the normally open contact of the Hazard Switch in the Turn/Hazard Switch. With the Hazard Switch "ON," voltage is applied to both front and rear Turn Lights. All of the Turn Lights and both Turn Indicators flash "ON" and "OFF."

The Front Marker Lights flash with the Hazard Lights "ON" just as they did in Turn Light operation. if the Headlight Switch is in "OFF," they flash "ON" when the Hazard Lights are "ON." If the Headlight Switch is in either "PARK" or "HEAD," they flash "ON" when the Hazard Lights are "OFF," and "OFF" when the Hazard Lights are "ON."

With the Hazard Lights on, the turn circuit is always open, and the Hazard Flasher controls the lights.

PARK/MARKER LIGHTS
Voltage is applied through Fuse 7, to the Headlight Switch at all times. With the Headlight Switch in "PARK" or "HEAD," voltage is applied to the Park and Marker Lights. The Front Marker Lights are grounded through the turn filament of the respective Front Park/Turn Light. The Front Marker Light lights.

STOP LIGHTS
Voltage is applied through Fuse 2 to the Brake Switch at all times. When the brake pedal is depressed, the Brake Switch closes and applies voltage to the High Level Stop Light and also to the LH and RH Tail) Stop-Turn Lights through the Turn/Hazard Switch.

REAR MARKER/LICENSE LIGHTS
Voltage is applied through Fuse 7 to the Light Switch at all times. When the Headlight Switch is in "PARK" or "HEAD," voltage is applied to all of the lights in this circuit.
