1673. INSPECT DRIVE BELT
(a) Check the belt for excessive wear, frayed cords etc.
HINT:
yIf any defect has been found, replace the drive belt.
yCracks on the rib side of a belt are considered acceptable. If
the belt has chunks missing from the ribs, it should be
replaced.
(b) Check that the belt fits properly in the ribbed grooves.
HINT:
Check with your hand to confirm that the belt has not slipped
out of the groove on the pulley.
4. CHECK ALTERNATOR WIRING
yCheck that the wiring is in good condition.
5. LISTEN FOR ABNORMAL NOISES FROM ALTERNATOR
y Check that there is no abnormal noise from the alternator while the engine is running.
6. INSPECT CHARGE WARNING LIGHT CIRCUIT
(1) Turn the ignition ON. Check that the charge warning light comes on.
(2) Start the engine. Check that the light goes off.
HINT:
If the light does not operate as specified, troubleshoot the charge warning light circuit.

1687. INSPECT CHARGING CIRCUIT WITHOUT LOAD
(a) If a battery/starter tester is
available, connect the tester to the
charging circuit as per instructions.
(b) If a tester is not available, connect
an ammeter and voltmeter to the
charging circuit as follows.
1Disconnect to the wire from
terminal B of the alternator and
connect it to the negative (-) pole
of the ammeter.
2Connect the positive (+) pole of the
ammeter to terminal B of the
alternator.
3Connect the positive (+) pole of the voltmeter to terminal B of the alternator.
4Ground the negative (-) pole of the voltmeter.
(c) Check the charging circuit
yWith the engine running from idle to 2,000 rpm, check the reading on the ammeter.
Standard amperage: 10A or less
Standard voltage: 13.2V---14.8V
8. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high beam headlights and place the blower switch at "4".
Check the reading on the ammeter.
Standard amperage: 20A or more
(b) HINT:
yIf the ammeter reading is less than standard amperage, repair the alternator.
yIf the battery is fully charged, the indication value will sometimes be less than standard amperage.Ammeter

169III. ALTERNATOR INSPECTION1. INSPECT ALTERNATOR
Structure of Alternator
(a) Inspect the rotor winding
1Inspect 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¸
2Inspect the rotor bending
Standard: less than 0.5 mm of radial motion
If it is not normal, calibrate or replace the rotor.PulleyBearing CoverBearing Rotor

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

303Figure 6 A/C System Electrical Appliance DiagramIII. Protecting Device1. Low temperature protection
Evaporator temperature sensor, when the sensed temperature is lower than 3°C, the compressor clutch
is de-energized and stops operation.
2. High temperature protection
Water temperature sensor, when the sensed water temperature reaches 109°C, the compressor clutch is
de-energized and stops operation.
3. Low pressure protection
When pressure sensed by the pressure switch is lower than 0.25MPa, the compressor clutch is de-
energized and stops operation.
4. Voltage protection
When the pressure sensed by the pressure switch reaches 1.7MPa, radiator fan rotates.
5. High pressure protection
When the pressure sensed by the pressure switch reaches 2.6MPa, the compressor clutch is de-energized
and stops operation.
6. Normal pressure
When system pressure reaches 0.25MPa~2.4MPa, control the A/C idle speed. Color of wire:R-Red Bl-Blue Y-Yellow Lg-Light green Br-Brown B-Black P-Pink G-Green W-White Gr-Gray
