Starter Motor - Westerbeke 12C- TWO Operator's Manual

STARTER MOTOR
DESCRIPTION
The starter is a new type, small, light-weight and is called a
high-speed internal-reduction starter. The pinion shafris
separate from the motor shaft; the pinion
~lides
only on the
pinion shaft. A rednction 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
Cfl",c'dng 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.

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
circult. '
If the solenoid clicks bnt nothing happens, the starter
motor is probably faulty.
