(5) WINDSHIELD WIPER The windshield wiper control switch is a three position rocker switch. Moving the switch from "Off" to the second position places the wiper in the low or slow cycle. Pushing the switch to the third position places the wiper motor in high or fast cycle. (6) ENGINE STARTING AID The ether starting aid is used for cold weather starting and is controlled by a switch, spring-loaded to the "Off" position. When the switch is held in the "On" position, the ether is injected into the engine intake manifold to aid in cold weather starting. In cold weather, below 50 o F (10 o C), turn the keyswitch (7) to the "Start" position.

Push the cold weather starting switch to the "On" position for three seconds while cranking , then release. If engine does not start, wait thirty seconds before repeating the procedure. (7) KEYSWITCH The key switch is a three position ("Off", "Run", "Start") switch. When it is moved to the "Run" position, the switch activates the accessory circuits. When moved to the "Start" position, the engine’s starting system is activated. After engine start, allow the switch to return to the spring-loaded "Run" position. (8) ENGINE SHUT DOWN The engine shutdown switch is a spring return rocker switch that is connected to the engine shutdown solenoid.

In order for this switch to work, the keyswitch must be in the "Run" position. The engine shutdown switch must be depressed until the engine comes to a complete stop. When the switch is held closed, fuel to the engine is shut off. (9) WINDSHIELD WIPER FUSE HOLDER This is a 15 amp.- dual element, time delay (slow blow) type fuse.
