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
specific gravity of battery fluid.
[Voltage]
Normal value : 12.4 to 12.8V
Limit (charging required):
12.4V or lower
Staring limit : 12V (at 20℃)
[Specific gravity]
Normal value : 1.22 to 1.29
Limit (Charging required) :
1.22 or lower
[Service life]
Variance in specific gravity
among cell : 0.04 or more
(1) Charge or change the battery when voltage
is lower than 12.4V or specific gravity is
lower than 1.22 (at 20℃).
(2) If the wiring and battery are normal, remove
the starter and go to
“3. Checking of pinion operation.”
* Use battery rated 12V-24AH or larger
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, field coil, armature,
and brush and replace faulty parts.
