9.15.1 Ignition Key Switch
The ignition key switch (Fig. 9 -56, 1) is located on the
lower right side of the front dash. It is a key-operated
switch used to start the engine and to run the vehicle.
Figure 9-56 Ignition Key Switch Positions
When the key is inserted into the ignition key switch, the
switch can be turned clockwise from the OFF position
(Fig. 9 -56, 2) to the RUN (3) and START (4) positions.
The START position is spring-loaded to return the switch
to the RUN position. This position must be manually held
in place for normal starting and for ether (cold start
option) to be injected into the cylinders.
In the OFF position (Fig. 9-56, 2), the entire electrical
system is shut down, with power at the ignition switch
terminals and the starter solenoid only.
In the RUN position (Fig. 9-56, 3), all controls and
indicators are operable.
When the park brake switch is ON and the transmission
is in (N) NEUTRAL, turning the ignition switch to the
START position (Fig. 9-56, 4) engages the starter to start
the engine and injects fuel into the cylinders.
If the key binds in the switch, check the key for defects
and the switch for foreign objects. Clean or remove foreign
material from the key as required. Check that the key is
not bent or excessively worn; replace a bent or worn key
with a new key.
Apply powdered graphite to the key, and insert and
withdraw the key from the switch several times to
distribute the graphite into the switch-lock mechanism.
During freezing temperatures, if the ignition key switch
fails to turn, or does not allow the key to be inserted,
warm the switch with a heat gun (blow-dryer), or use
liquid lock deicer to help evaporate frozen moisture from
within the switch.
IMPORTANT: Only use graphite or a liquid lock deicer
within the switch. Replace a defective switch.
