Precautions

1. Check positive and negative wire of battery is con-

nected correctly.

2. When performing quick charge to battery, please

uncouple battery wire.

3. Do not test with high-pressure insulation resistance

tester.

4. do not uncouple battery wire during engine running.

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: OK

White: requiring charge

Black: replacing battery

2. 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.

5. 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.

7. 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.
z Uncouple wire on engine terminal B, and connect wire

on negative (-) test bar of ampere meter.

z Connect positive (+) test bar of ampere meter to alter-

nator terminal B.

z Connect positive (+) test bar of voltmeter to alternator

terminal B.

z Connect 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.
