9. STARTING MOTOR 9.1.5 Inspection and maintenance (1) Armature (a) Commutator outside diameter Measure the commutator outside diameter and replace the commutator if the measured value is less than the limit. mm (b) Armature coil continuity test Check continuity between commutator seg- ments with a multimeter. Good if continuity exists. In case of no continuity (coil disconnection), replace the armature. (c) Armature coil insulation test Inspect the continuity between a commuta- tor segment and the shaft or core with a multimeter. Good if no continuity exists. If continuity exists (coil short circuit), replace the armature. 82E-5 – 98E-5 SERIES 9-9 Standard Limit 36.5 35.5
