Key Switch
Key switch (1, Figure 32-11) is a three-position (OFF,
RUN, START) switch. When the switch is rotated one
position clockwise, it is in the RUN position and all
electrical circuits (except start) are activated.
With the selector switch in neutral, rotate the key
switch fully clockwise to the START position, and hold
this position until the engine starts. The START posi-
tion is spring-loaded to return to RUN when the key is
released. With the truck stopped, turn the key switch
counterclockwise to OFF for normal engine shutdown.
Use the engine shutdown switch on the center console
if the engine does not shut off with the key switch.
NOTE: A ground level shutdown switch is located on
the lower, front left side of the truck.
