6D-2 ENGINE ELECTRICAL
silicone jacket withstands very high temperatures and
also provides an excellent insulator for the higher
voltage of the system.
S p a r k Plugs
Resistor type, tapered seat spark plugs are used
on all engines, except those with aluminum heads.
Ignition Switch
The mechanical switch is located in the steering
column on the right hand side just below the steering

CRANKING SYSTEM
The cranking circuit consists of the battery,
starting motor, ignition switch, and related electrical
wiring.
Starter Motor
Wound field starter motors have pole pieces,
arranged around the armature, that are energized by
wound field coils.
Solenoid
Enclosed shift lever cranking motors have the
shift lever mechanism and the solenoid plunger
enclosed in the drive housing, protecting them from
exposure to dirt, icing conditions and splash.
