Procedure

  1. Stator winding resistance values is a test of winding conti­
  2. Testing for a “grounded” condition: Any resistance read­
  3. Testing for a “shorted” condition: Any resistance reading
  4. If stator tests good and wire continuity tests good, refer
  5. An open circuit condition
  6. A “short-to-ground” condition
  7. A short circuit between windings
  8. Disconnect Wires 11, 22, 33, 44 from the receptacle
  9. Make sure all of the disconnected leads are isolated
