III. ALTERNATOR INSPECTION
1. INSPECT ALTERNATOR
Structure of Alternator
(a) Inspect the rotor winding
1 Inspect the resistance of the rotor winding
Place the multimeter at R x 1, connect 2 pens and 2 slip
rings of the rotor.
Standard resistance: 2.7---3.1 ¸
2 Inspect the rotor bending
Standard: less than 0.5 mm of radial motion
If it is not normal, calibrate or replace the rotor.
