4. Inspect: • Armature coils (insulation/continuity). Out of specification ➔ Replace the motor. ▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼▼
How to inspect the excitation coils: • Connect the pocket tester and check continuity (1) and insulation (2). Check the armature resistance: • Armature coil resistance: Continuity check (1): 0 Ω at 20°C (68°F) Insulation check (2): Over 1 MΩ at 20°C (68°F)
•
If the resistance is not correct, replace the starter motor.

5. Measure: • Brush lenght Out of specification ➔ Replace all brushes at once. Brush lenght limit (a): 5.0 mm 6. Inspect: • Brush spring strength Worn out ➔ Replace all springs at once.
Brush spring strength: 8.82 N (899 gf)
7. Inspect: • Bearings (1) • Oil seal (2) • O-Rings • Bush (3)
