5. REMOVE REAR END FRAME (a) Remove the four nuts. (b) Using SST, remove the rear end frame and four terminal insulators. SST 09286-46011 6. REMOVE ROTOR FROM DRIVE END FRAME INSPECTION OF ALTERNATOR Rotor 1. CHECK ROTOR FOR OPEN CIRCUIT Using an ohmmeter, check for continuity between the slip rings. Standard resistance: Less than 3 Ω If there is no continuity, replace the rotor. 2. CHECK ROTOR FOR GROUND Using an ohmmeter, check that there is no continuity between the slip ring and the rotor. If there is continuity, replace the rotor. 3. INSPECT SLIP RINGS (a) Check that the slip rings are not rough or scored. If rough or scored, replace the rotor. (b) Using calipers, measure the slip ring diameter. Standard diameter: 14.4 mm (0.567 in.) Minimum diameter: 14.0 mm (0.551 in.) If the diameter of the slip ring is less than the minimum, replace the rotor. Stator 1. INSPECT STATOR FOR OPEN CIRCUIT Using an ohmmeter, check all leads for continuity. If there is no continuity, replace the drive end frame assembly.
