ELECTRICAL SYSTEM
2. Connect the the W/Bl lead, and disconnect
Starter
clutch and generator rotor
the
yellow lead from the alternator. The
coils @ and
@
are
good
if the tester reads
16.5V
or more at 5,000 rpm.
If the coils mentioned in items 1 and are in
good condition, the alternaotr and rectifier
are in good order. If the tester reads
otherwise, replace the alternator.

Rotor
Regulator
Check the regulator for performance, as fol-
lows. Restore the three phase
circuit
to the
normal hook-up, placing the switch and regu-
lator back in service. Run the engine and check
the voltage again. If the
tester
reads
less
than
I4V or higher than 15.5V at 5,000 rpm, the
cause
is
faulty regulator. The regulator is not a
disassembly
typk
so it must be replaced if faulty.
STARTER SYSTEM
The starter system is shown in the diagram
below:
namely, the starter motor, relay, starter
switch and battery. Depressing the starter but-
ton (on the right handle) energizes the relay to
close its contact points, thereby connecting the
-
starter
motor to the battery. The motor draws
about 80 amperes to start the engine.

See
page 7-29 with respect to the removal
procedures for the rotor and starter clutch.
INSPECTION
Inspect the components to
be sure that
wiring
connections
are
all tight and that the circuit
wires are in good
condition. Make sure, too,
that each component is securely grounded.
When the system is in good condition, the
starter relay will make a single clattering sound
as the starter button is depressed and im-
mediately the motor will crank the engine.
When this clattering noise is not heard or when
the starter motor fails to turn the engine over
possibly means that either
the relay is not being
properly energized due to a run-down battery,
or the relay coil is open.
If the relay "clatters" but the motor
will
not
1
crank, then it is Likely that the relay contact
points are defective or the motor
is
internally
open-circuited.
