Section 10. Electrical System
• In the RUN position with the Park Lock
engaged, park lock warning, oil pressure and
alternator lights must be ON. Press Bulb
Check switch; remaining warning lights must
turn ON.
• In the THERMO START position, the ignition
switch energizes the Thermo Start plug (Fig.
10.24) which ignites a fuel/air mixture in the
intake manifold to facilitate cold weather
starting. Refer to paragraph 10.5.5 for
Thermo Start plug removal and installation
instructions.
• In the START position (with the parking lock
engaged and the travel select lever in neutral)
the starter pinion engages the flywheel to
start the engine.
If the key binds in the lock, check for a sticky,
painted or bent key. If key is sticky, clean key. If
key is painted, remove paint. If key is bent,
straighten key. If the key is straight and usable,
sprinkle some powdered graphite on the sides of
the key and insert key in lock several times to
distribute the graphite. If the lock should fail to
accept key or fail to turn due to freezing tempera-
tures, warm the key switch using a hair dryer or use
a liquid lock deicer to lower the freezing point and
evaporate the moisture within the lock.
IMPORTANT: Use only graphite or a liquid lock
deicer within the lock. Severe lock malfunctions
may require the services of a locksmith.
