  4. Repeat Step 6 using Wire 2 and Wire 44.INFINITY
  5. Stator winding resistance values is a test of winding conti­
  6. Testing for a “grounded” condition: Any resistance read­
  7. Testing for a “shorted” condition: Any resistance reading
  8. If stator tests good and wire continuity tests good, refer
