Inspect commutator for insulator depth. Correct or replace if below limit.
Commutator insulator depth "a"
Standard: 0.5 mm (0.020 in.)
Limit: 0.2 mm (0.008 in.)
Ground test
Check commutator and armature core. If there is continuity, armature is grounded and must be replaced.
Open circuit test
Check for continuity between segments. If there is no continuity at any test point, there is an open circuit and armature must be replaced.
