Ignition Switch and Key
The ignition switch can be turned to four positions: ACCESSORY, OFF, ON, and START. See Fig..
Fig. 1, Ignition Switch Positions
The key can be inserted and removed only in the OFF position. The headlights (low beams), taillights, brake lights, road lights, clearance lights, turn signals, hazard warning lights, horn, CB radio, clock, and electric oil pan heater operate with the ignition switch in the OFF position, regardless of whether the key is inserted.
In the ACCESSORY position, the key is turned counterclockwise. All of the components that are operable in the OFF position are operable in the ACCESSORY position, as well as the radio (if so equipped), mirror heat, air dryer, and backup lights.
Important: The propane engine is equipped with an amber wait to start indicator. The indicator illuminates when the ignition is in the RUN position prior to engine start-up. Do not crank the engine until the wait to start indicator goes out. See the "Ametek Panel" information in this chapter for the location of the wait to start indicator.
Turn the key fully clockwise to the START position to start the engine. When the engine starts, release the key.
All electrical systems are operable in the ON position. The warning lights and the buzzer for low air pressure and low oil pressure operate until minimum pressures are built up.
