170(b) Inspect the stator winding
1Inspect 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.
2Inspect 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.AlternatorInspection of Armature Winding Ground

175II. DETAILED SOLUTION PROCEDURE1. THE WHOLE COMBINATION METER
DOSE NOT OPERATE.
(a) Inspect fuse
1Check fuse CLUSTER (10A) in the main fuse
box for continuity.
2Check fuse AM (30A) in the main fuse box
for continuity.
3Check fuse MAIN (80A) in the fuse box for
continuity.
Result and solution: If a certain fuse is burnt, replace a fuse
with the same capacity.Ignition SwitchMain Fuse BoxCombined Meter AssemblyBatteryFuse Box
