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.

(b) Inspect the stator winding
1
Inspect the resistance of the stator winding
Place the multimeter at R x 1, connect 2 pens of the
meter to any of the 2 pens wires of the armature winding
respectively. There must be continuity. Where the
resistance reading is infinitely great shows an open circuit.
2
Inspect the winding ground
Place the multimeter at R x 1, connect one pole of the
meter to the pole wires of the armature winding
respectively and the other pole of the meter to the stator
core. If the resistance reading is infinitely great, the
armature winding is well-insulated. If not, it needs repairing
and replacing.
IV. ALTERNATOR ASSEMBLY REPLACEMENT (MR479Q, MR479QA, MR481QA)
(a) Disconnect the alternator connector.
(b) Loosen the Bolt A, B, C
(c) Loosen the V-belt. Then remove the alternator.
2. INSTALL ALTERNATOR ASSEMBLY
Torque:
M10 bolt 15N.m (154kgf.cm, 9ft.lbf)
Tension adjustment for V-belt:
When the center of the belt receives a 50N of downward pressure, there is a 10 mm of deflection.
