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:
STANDARD RESTANCE:：80-150Q
