ELECTRIC STARTER
5-64
EAS24790
CHECKING THE STARTER MOTOR
1. Check:
• Commutator
Dirt
→
Clean with 600 grit sandpaper.
2. Measure:
• Commutator diameter “1”
Out of specification
→
Replace the starter
motor.
3. Measure:
• Mica undercut “a”
Out of specification
→
Scrape the mica to the
proper measurement with a hacksaw blade
that has been grounded to fit the commutator.
NOTE:
The mica of the commutator must be undercut to
ensure proper operation of the commutator.
4. Measure:
• Armature assembly resistances (commutator
and insulation)
Out of specification
→
Replace the starter
motor.
