Armature Coil Test
- If the surface is dirty or burnt, correct it with sandpaper (No. 400) or a lathe.
- Using an ohmmeter check that the resistance between the segments of the commutator. See Fig 1. Ensure resistance is within specification. See STARTER SPECIFICATIONS . If any of the segments do not meet specification, replace the armature.
- Check the commutator for ground. Using an ohmmeter, check the resistance between the commutator and armature coil core. See Fig 1. Ensure resistance is within specification. See STARTER SPECIFICATIONS . If resistance does not meet specification, replace the armature.
- Using vernier calipers, measure the commutator length. See Fig 2. If the length is greater than maximum, replace the armature.
