* Most ohmmeters do not give accurate readings when measuring less than 1 ohm. The stator can be considered good if a low resistance
reading (continuity) is obtained and there is no evidence of shorted windings (discoloration). Do not confuse a low resistance reading with
a reading indicating a shorted winding.
