Bench Testing: Rotor

Using an ohmmeter, ensure continuity (1.8-3.0 ohms on Civic and CR-V) exists between rotor slip rings. See Fig 1 . If continuity does not exist, replace generator. Ensure continuity does not exist between slip rings and rotor, or between slip rings and rotor shaft. If continuity exists, replace generator.
