Problem and check item Description Remedy
(1) Starter does not run or only "click" sound is heard.
1. Checking of
continuity of
wiring
Check S terminal and B terminal
for deformation, looseness,
rusting, or dust sticking. Carefully
check inserting method of the S
terminal.
If not abnormal, set the key
switch to START position while
cranking (no ignition of engine)
and check if voltage is applied to
the S terminal and B terminal of
starter motor.

(1) When no voltage is applied to the
S terminal and B terminal, check
continuity of the terminals and
key switch and repair or replace
if necessary.
(2) If voltage is applied to the
S terminal and B terminal,
go to "2. Battery checking."
2. Battery
checking
Check battery voltage and
specifi c gravity of battery fl uid.
[Voltage]
Normal value : 12.4 to 12.8V
Limit (charging required)
: 12.4V or lower
Staring limit : 12V (at 20°C)
[Specifi c gravity]
Normal value : 1.22 to 1.29
Limit (Charging required)
: 1.22 or lower
[Service life]
Variance in specifi c gravity
among cell : 0.04 or more
BATTERY
GRAVITY METER
(1) Charge or change the battery when
voltage is lower than 12.4V or
specifi c gravity is lower than
1.22 (at 20°C).
(2) If the wiring and battery are normal,
remove the starter and go to
"3. Checking of pinion operation."
3. Checking
of pinion
operation
Check if the pinion operates or
sound of magnetic switch contactor
is heard.
If the pinion does not operate
or magnetic switch sound is not
heard, check continuity of each coil
of magnetic switch.
(1) If the pinion operates or contactor
sound is heard, step to "4.
Checking
of magnetic switch (1)."
(2) In case of no continuity
Replace the magnetic switch.
(3) When continuity is OK
Step to "4. Checking of magnetic
switch (2)."
4. Checking
of magnetic
switch
(1) Operate the magnetic switch
and check B-M terminals

(1) In case of no continuity
Contact continuity failure.
Replace the magnetic switch.
(2) When continuity is OK
Step to "5. Motor checking."
(2) Check the magnetic switch
plunger and bobbin interior for
dust sticking or rusting.
(1) Clean the plunger. If the bobbin
interior is contaminated, replace
the magnetic switch.
5. Motor
checking
Connect the (+) side of the
battery to the M terminal of
magnetic switch and check if the
motor runs.

(1) If the motor does not run, check
electric circuit inside the motor,
fi eld coil, armature, and brush and
replace faulty parts.
