Rotor Slip Ring Test: Notes

Check the resistance between the slip rings. There should be 1.8-3.0 ohms.
- If resistance meets the specification, go to step 2.
- If resistance does not meet the specification, replace the alternator.

Check that there is no continuity between the slip rings and the rotor or rotor shaft.
If the rotor fails either continuity check, replace the alternator.
