MAINTENENCE--ELECTRICAL
However, if there is a few ohms resistance, the relay
may be good; check that there is actually voltage to the
relay before deciding that the relay is defective. To
check for the voltage, first turn the meter to 20V DC,
connect the
-
meter lead to the yellow/red lead which
was disconnected from the relay, and connect the
+
meter lead to the black lead. Pulling the clutch lever,
push the starter button, and see if the meter reads
battery voltage. If the meter does not, there is wiring,
starter lockout switch, or starter switch trouble.
If
the meter
reads
battery voltage but the relay does not
click, the relay is
defective.

Starter lockout switch test
Remove the fuel tank (Pg. 46), and disconnect the
two starter lockout switch black leads.
Connect an
ohmmeter set to the x 1
n
range across the two black
leads. Pull the clutch lever, and see if the meter reads
zero ohms. If the meter does not, the starter lockout
switch is defective and must be replaced.
A. Starter Lockout Switch Leed.
Starter switch test
Remove the fuel tank
(Pg.
46), and disconnect the
3-pin connector from the right switch housing. Connect
an ohmmeter set to the x 1
n
range across the brown
and the black
leads.
Push the starter button with the
engine stop switch to "RUN", and see if the meter reads
zero ohms. If the meter does not, the starter switch or
engine
stop
switch is defective and the entire right
switch housing assembly must be
replaced.

Starter Motor
The starter motor is installed in a constant-mesh
arrangement to transmit starter motor rotation to
the crankshaft. A clutch disengages the starter motor
once the engine starts. (See the Starter Motor Clutch
Paragraph, Pg. 247).
Fig. K42 shows starter motor construction.
The
field coils

CD
,
and the armature windings
®
are connected
to the commutator
@
and receive their current through
the brushes
(!)
.
If the brushes are not making good
contact, no starter motor current will flow since the
field coils and armature windings are connected in
series, and the motor will not turn over. A short or open
circuit in a coil or winding may also cause the motor to
be inoperative. Particles from brush wear may be another
cause of starter motor failure; these particles may get
into the bearing at the rear of the motor, causing heat
seizure.
Carbon brushes
Worn brushes or weak springs will cause poor brush
contact.
Measure the length of the brushes, and
replace
both
if either one is worn down to less than the service limit.
