ELECTRIC STARTING SYSTEM
REMOVING THE STARTER MOTOR
1. Remove:
• seat assy.
• helmet box
• starter motor
CHECKING THE STARTER MOTOR
1. Check:
• commutator
Dirt
Clean with 600-grit sandpaper.
2. Measure:
• commutator diameter a
Out of specification
Replace the starter
motor.
3. Measure:
• armature assembly resistances (commuta-
tor and insulation)
Out of specification
Replace the starter
motor.
a. Measure the armature assembly resistances
with the pocket tester.
b. If any resistance is out of specification,
replace the starter motor.
4. Measure:
• brush length a
Out of specification
Replace the brushes
as a set.
