  2. Remove armature from growler. Measure insulation resistance between commutator and core. If continuity exists, replace armature. Measure insulation resistance between commutator and shaft. If continuity exists, replace armature.
  3. Inspect for continuity between each commutator segment. If an open exists between any 2 segments, replace armature.
