Commutator Test

  1. Place the armature on a pair of V- blocks and check the runout by using a dial gauge. See STARTER SPECIFICATIONS .
  2. Check the outer diameter of the commutator. See STARTER SPECIFICATIONS .
  3. Check the depth of the undercut between segments. See STARTER SPECIFICATIONS .
  4. If runout, diameter or undercut are not within specification, replace commutator.
