STARTER MOTOR
DESCRIPTION
The starter is a new type, small, light-weight and is called a
high-speed internal-reduction starter. The pinion shaft is
separate
from the motor shaft; the pinion slides only on the
pinion shaft. A reduction gear is installed between the motor
shaft
and a pinion shaft. The pinion sliding part is not
exposed outside the starter
so that the pinion may slide
smoothly-without becoming fouled with dust and grease. The
motor shaft
is supported at both ends on ball bearings. The
lever mechanism, switch and overrunning clutch inner circuit
are identical
to conventional ones.

TROUBLESHOOTING
SOLENOID
A WARNING: The following emergency starting
procedures must not be used with gasoline engines.
Sparks could cause an explosion and fire.
Prior to testing, make certain the ships batteries are at full
charge
and that the starting system wiring connections
(terminals) are clean
and tight. Pay particular attention to
the ground wire connections on the engine block.
To check the wiring, try cranking the starter for a few
seconds, never more than 10 seconds at a time, then run your
hand along the wires
and terminals looking for warm spots
that indicate resistance. Repair or replace
any trouble spots.
Using a multimeter, test the voltage between the positive
terminal stud on the start solenoid
and the engine block
(ground).
If you read 12 volts, the starter is faulty.

IGNITION
TERMINAL
r-...----(M) TERMINAL
To test the ignition circuit, locate the ignition(s) terminal (it
is one of
the small terminal studs and is wired to the ignition
circuit).
Use a screwdriver, don't touch the blade, to jump
from that ignition terminal
to the positive battery connection
terminal
on the solenoid.
If the starter cranks, the fault lies with the ignition
circuit.
If the solenoid clicks but nothing happens, the starter
motor is probably faulty.

If nothing happens at all, the solenoid is not getting
current.. Check the battery isolation switch and inspect the
wiring connections. it
is also possible that the solenoid is
defective.
A WARNING: There will be arching and sparks will
fly when jumping terminals. Be certain the engine
space is free of potentially explosive fumes, especially
gasoline, and that there are NO flammable solvents or
materials stored nearby.
