4-5-2 Removal and Inspection of Starter Mechanism
A. Circuit of Starter Mechanism:
a. Circuit Description:
Ignition Switch ON
→
Brake Switch ON
→
Starter Relay
→
Starter Switch ON
→
Starter Motor started.
B. Inspection of Starter Relay:
a. Test the Ohmic value between each
terminal of the coil. (see Figure 2)
b. Set up the range as x10
Ω
.
c. The value of electric resistance
of the starter relay must be
50
∼
70
Ω
, replace when value
out of this range.
C. Connect the coil end with 12V
Power supply (as Figure 2), a beep
sound means they are connected.
D. Inspection of Starter Motor:
a. Inspect wearness and roughness
of contact surface on carbon brush (1).
b. Inspect the surface wearness and
burning of the commutator (2).
c. Measure the outside diameter of the
Commutator (2).
d. The commutator and the armature
core (3) or shaft (4) should not be
passed through between.
e. Each segment and the commutator
should be passed through.
f. The standard length of carbon brush
should be 5.5mm. Replace if it is
under 3.0mm.
g.The standard outside diameter of
commutator should be16mm.
Replace if it is under 15.5mm.
