Bench Testing: Rotor
- Check Rotor Coil For Continuity - Check to make sure that there is continuity between the slip rings. See Fig 1 . Resistance should be 3.1 ohms. If resistance is extremely low, there is a short. If there is no continuity or if there is a short, replace generator. See GENERATOR under REMOVAL & INSTALLATION.
- Check Rotor Coil For Ground - Check to make sure that there is no continuity between the slip rings and the rotor shaft. See Fig 2 . If there is continuity, replace generator. See GENERATOR under REMOVAL & INSTALLATION.
