sound is heard.
Problem and check item Description Remedy
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 C)
[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
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).”
(1) Charge or change the battery when
voltage is lower than 12.4V or specific
gravity is lower than 1.22 (at 20 C).
(2) If the wiring and battery are normal,
remove the star ter and go to “3.
Checking of pinion operation.”
4. Checking of
magnetic
switch
(1) Operate the magnetic switch
and check B-M terminals
(2) Check the magnetic switch
plunger and bobbin interior for
dust sticking or rusting.
(1) In case of no continuity
Contact continuity failure. Replace the
magnetic switch.
(2) When continuity is OK
Step to “5. Motor checking.”
(1) Clean the plunger. If the bobbin interior
is contaminated, replace the magnetic
switch.
5. Motor checking Connect the (+) side of the
batter y 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.
