LIGHTING SYSTEM.

The wiring of the lighting system is shown in Fig. 16. The lighting circuit is protected by an overload circuit breaker mounted on
the back of the main light switch and no replaceable fuse is required. It clicks off and on in the event of a short circuit in the
wiring.
The upper and lower headlight beams are cohtrolled by a foot switch located on the toe board at the left of the clutch pedal.

MAIN LIGHT SWITCH.

The main light switch Fig. 17 has three positions. When the switch control knob is all the way in, all lights are turned off. Pulling
it out to the first position turns on the parking lights; out to the second position, the driving lights.
Should it be necessary to install a new light switch, refer to the wiring diagram, which indicates the correct wires to install on the
several terminals.
To remove the switch, loosen the setscrew in the side of the switch control knob and remove the knob by unscrewing. The
retaining nut may then be removed and the switch removed through the rear of the instrument panel.
