- Set ohmmeter on X1 scale. Measure resistance between slip rings. On Mark VIII, Mustang and Taurus, resistance should be 2.0-3.9 ohms. On Probe and Villager, resistance should be 2.5-3.6 ohms.
- Higher resistance indicates damaged slip ring solder connection or broken wire. Lower resistance indicates shorted wire or slip ring. Replace rotor if it does not meet specification.
- Connect one ohmmeter probe to slip ring and the other probe to rotor core. Replace rotor if ohmmeter indication is other than infinity. Damaged slip ring terminals or solder touching rotor shaft can cause shorted condition.
