1. Check battery voltage.(a) If extinguishing time of engine is not more than 20 minutes
after driving, please turn on ignition switch and electric
equipment (head lamp, blower motor and rear window
defog line etc.) for about 60 seconds to eliminate surface
charging during driving.
(b) Turn ignition switch to OFF, and then switch off electric
equipment system.
(c) Measure the voltage between battery negative (-) terminal
and positive (+) terminal.
Standard voltage: 12.5~12.9V at 20.
Hint: if the voltage is lower than standard
specification, please charge battery.
(d) As shown in the diagram, check battery window.
Hints:Green: OKWhite: requiring chargeBlack: replacing battery2. Check battery joint, fusible link and slow fuse (100A).(a) Check battery joint is loose or eroded.
(b) Check fast fuse and slow fuse (100A) are in conduction.3. Check drive belt.(a) Check belt is excessively worn or cable is broken etc.
Hints:If any inferior part is found, please replace drive
belt.It is allowable for the crack at the edge of drive belt
rib.
If there is block falling with belt rib, please replace with
new belt.
(b) Check the belt is correctly installed in guide groove.
Hint:Check with hands to ensure that the belt does
not slide out from the groove of pulley bottom.4. Visually check alternator wire harness.Check the condition of wire is perfect.Starting and charging - Charging systemOn-vehicle inspectionGreen White Black5. Listen to whether there is abnormal sound with alternator.There should not be abnormal sound with alternator during engine running.6. Check the circuit of charge alarm light.(a) Turn ignition switch to “ON”, and check charge alarm light is on.
(b) Start engine, and charge alarm light should be off.
Hint: if the function of charge alarm light does not conform to the regulation, please perform
trouble shooting to the circuit of charge alarm light.82

Starting and charging - Charging system7. Check charging system circuit at no load.(a) If there is battery/alternator tester, please connect tester
to charging system circuit as manufacturer instruction.
(b) If there is no battery/alternator tester, please connect volt-
meter to charging system circuit as the following way.
zUncouple wire on engine terminal B, and connect wire
on negative (-) test bar of ampere meter.
zConnect positive (+) test bar of ampere meter to alter-
nator terminal B.
zConnect positive (+) test bar of voltmeter to alternator
terminal B.
zConnect negative test bar of voltmeter to earth.8. Check charging system circuit at load.(a) Turn on high beam of front combination lamps with engine running at 2000rpm,and turn blower to
“HI” position.
(b) Check the reading of ampere meter.
Standard amperage: 30A or more.
Hints:If amperage is less than standard value, please repair alternator.If battery is under the state of full charge, amperage may be less than standard value sometimes. (c) Check charge system circuit.
(1) Check the readings of ampere meter and voltmeter with engine from idle speed to 2000rpm.
Standard current: 10A or less.
Standard voltage: 12.9~14.9V.
Hints:If voltmeter reading is more than standard value, please replace with new voltage regulator.If voltmeter reading is less than standard value, please check voltage regulator and alternator
as the following way.
(2) Earth terminal F, start engine and check voltage of
terminal B.
Hints:If voltmeter reading is more than standard value,
please replace with new voltage regulator.If voltmeter reading is less than standard value,
please check alternator.83Ampere meter

2. Remove drive belt.Slowly turn drive belt tensioner clockwise to loosen the belt,
then remove drive belt and put back the tensioner slowly to
completely loosen it.3. Remove alternator components.(a) Remove rubber cover and nuts.
(b) Uncouple alternator joint.
(c) Remove 2 bolts and alternator.4. Install alternator components.Torque:12mm head bolt : m
