Armature Test

WARNING: This page is about a different car, the 2001 Honda Prelude, 2001 Honda Odyssey, 2001 Honda CR-V, and 2001 Honda Accord. However, it is still accessible from the selected car via links, so may be relevant.
  1. Place armature in growler. Turn on growler and hold hacksaw blade over armature. Slowly rotate armature. If armature attracts hacksaw blade or if hacksaw blade vibrates, armature is defective and must be replaced. If blade does not respond as described, go to next step.
  2. Remove armature from growler. Check continuity between commutator and armature core, and between commutator and armature shaft. Continuity should not exist. If continuity exists in either case, replace armature.
  3. Check for continuity between each commutator segment. Continuity should exist. If an open circuit exists between any 2 segments, replace armature.
  4. Inspect armature for wear or damage due to contact with field coil magnets. Clean commutator surface, and polish with No. 500-600 sandpaper (if necessary). If surface is scored, out-of-round or pitted, turn commutator on a lathe.
  5. If mica depth is not within specification, undercut with a hacksaw blade to minimum depth. See STARTER SPECIFICATIONS .
