TROUBLE SHOOTING FOR STARTER MOTOR :
COMPLAINT
STEPS FOR CHECKING
CAUSE AND CORRECTIVE ACTION
Starter Motor not
working.
A) Ensure that the battery is fully
charged. Check Specific gravity of
electrolyte in each cell. It should
be as specified
B)
Fuse (10A) to be intact.
C)
All terminal screws/nuts at the
starter motor. Earthing point on
the engine,battery starter relay and
the neutral switch should be clean
and tightened adequately.
D)
Ignition switch must be in ‘ON’
position and engine kill switch in
run position.
E)
Start button pressed.
1.1 Check for 12 V D.C. supply at the
starter motor terminal S+ with a
voltmeter (VM) D.C. Range. 25V.
1.2 If the S.M. is checked as per
1.1.1 and no supply is available
at the S+ terminal then cover
the following steps.
Hear for click noise of the starter
relay while pressing starter button.
a)
Refer 1.2.1 & 1.2.2 if click noise
comes
b)
Refer 1.3 if click noise does not
come
1.1.1 No response indicates that 12 V D.C.
supply is not available at the starter motor
(S.M.) terminal S+. The starter circuit
needs to be checked. Refer clause 1.2
below.
1.1.2 If the V.M. indicates 12V.D.C . supply at
the S.M. Terminal S+, then the S.M. is
faulty.
1.1.3 To cross check connect bVE
terminal B1 directly to the S.M. +VE
terminal S+ with a 6 mm
2
cable. If the S.M.
does not respond then it should be
replaced.
1.2.1 If the click noise is present it indicates that
the relay is operating but there is no output
from the Relay. Check for 12VD.C. supply
between the input (R1) of the Relay and
chassis ground. (Start button not pressed)
If the supply is present then the cover the
following steps.
1.2.2 Check for 12V DC supply between R2 and
Ground. If the supply is present, Check
for voltage drop between R1 & R2. If the
drop is more than 2V, (start button pressed)
then relay is faulty, replace the same.
To cross check, refer 1.1.3. If starter
motor is ok, check continuity of wire from
relay to starter motor.
