Rotor Test

  1. Remove rotor from generator. Measure resistance between rotor slip ring. Resistance should be 2.3-2.7 ohms. Replace rotor if resistance is not within specification.
  2. Connect one ohmmeter probe to either slip ring. Connect other probe to rotor shaft. Resistance other than infinity indicates rotor is shorted to shaft and must be replaced. Damaged slip ring terminals or solder touching rotor shaft can cause shorted condition.
