STARTER MOTOR INSPECITION
CARBON BRUSHES
When the brushes are worn, the motor will be
unable to produce sufficient torque, and the engine
will be difficult to turn over. To prevent the ,
periodically inspect the length of the brushes and
replace them when they are too short or chipping.
Service limit
:
3.5mm(0.14in)
Commutator
If the commutator surface is dirty, starting
performance will decrease. Polish the commutator
with #400 or similar fine emery paper when it is dirty.
Service limit
:
0.2mm(0.008in)
Armature coil
using the pocket tester, check the coil for open and
ground by plcing probe pins on each commutator
segment and rotor core and on any two segments
at various places. With the brushes lifted off the
commutator surface. If the coil is found to be
open-circuited or grounded, replace the armatrue.
Starter relay inspection
z
Disconnect lead wire (R/W) of the starter motor.
Turn on the igniton switch and squeeze the front
or rear brake lever, then inspect the continuity
between the Red and Red/White lead wires at
the starter relay when pushing the starter
button.
If the starter relay is in sound condition,
continuity is found.
•
Disconnect the starter relay lead wire couple.
Check the coil for “open”, “ground” and ohic
resistance. The coil is in good condition, if the
resistance is as follows:
