CHARGING OF BATTERY

Warning: Keep the battery away from any flammable materials. If not, the gas emitted

from the battery liquid that is easily flammable may cause severe injury or
even death of people.

Note: In order to prevent the battery and other components from being damaged, all

attached devices and the generator should be shut down before maintaining or
charging the battery.

REMOVAL/INSTALLATION OF THE GENERATOR

Warning: When connecting wires of the battery are in on-state, and at this time if you

contact the generator terminal with the car body, sparks will happen. It may
cause body injury, fire and the sparks may damage electrical components.
Therefore, before carrying the following operation, you must disconnect the
negative grid of the battery first.

Note:

—

The negative grid of battery should be

disconnected first during removal, and should
be connected last during installation. It will
avoid the damage to battery or any other
electrical component.

—

In order to prevent the battery or other

components from being damaged, all auxiliary
devices and the generator should be shut down
during maintaining or charging the battery.

—

Place the battery in water basin so as to

prevent it from overheating; water level of the
basin should be about half of the battery
height. During charging, disconnect connectors
of the battery and make sure to keep the upper

T-5

part of the battery away from water.

—

Connect the battery to the charger, and adjust
the charging current accordingly.

As heat discharged by the exhaust manifold could damage the generator, you must
ensure that the heat discharging guard and insulation device are firmly installed on the
generator.

Installation of generator bracket:

—

Disconnect the negative grid of the battery.

—

Mount the double-ended stud on top of

cylinder cover.

—

Install the bracket of generator.

—

Tighten flange nut of the double-ended stud
and bolt on the cylinder body, the tightening
torque should be 40±4Nm.

The installing steps are reverse to those for
removal.

Installation of generator:

—

Disconnect the negative grid of the battery.

—

Align one end of the generator with the

installation hole of bracket, and push it in by
force until the installation hole and the shaft
hole of the generator are aligned.

—

Use a long bolt and an Allen screw

respectively to install the generator on its
bracket, with a tightening torque of
25±2N.m.

—

Connect the positive power source wire with
the generator and the cable lug of the battery
warning lamp to the wiring terminal.

Note: The wiring harness must not be

grounding so as to avoid from
catching fire.

The installing steps are reverse to those for
removal.

T-6

Installation of driving belt and tensioner
assembly:

—

Disconnect the negative grid of the battery.

—

Use 3 M8 Allen screws to install the

tensioner assembly on the bracket of the
generator, with a tightening torque of
25±2N.m.

—

Install the multi-wedged belting; Pull out the
pin on the tensioner assembly so as to
tension the driving belts in the tensioner
pulley. Inspect the driving belts to see
whether they are all inserted properly in the
driving wedge of the pulley wheel.

The installing steps are reverse to those for
removal.

Adjusting method of multi-wedge belting
and tensioner assembly alignment:

—Disconnect the negative grid of the battery.

—Use spanner to rotate the engine crankshaft

belt pulley to drive the multi-wedged belting
for at least one revolution.

—Observe the alignment status of the multi

-wedge belting and tensioner assembly, if
the multi-wedge belting center exceeds the
tensioner assembly center, then remove the
tensioner assembly and add spacers to adjust
the centering.

The installing steps are reverse to those for

removal.

Overhaul of generator:

—Inspect the accuracy of deflexion and

tension value of the driving belt, if it does
not comply with the requirement, then the
driving belts should be replaced.

—Shut down all the electro-devices, turn the

ignition switch to start the engine, inspect
the rotation process of the engine to see
whether the rotation of generator is smooth
without any noise.

T-7

—Use voltmeter to measure the voltage value

of the generator output terminal.

Standard value: Engine idling; Temperature: 20
℃

, Output voltage: 13-15V.

—Switch on the following devices and observe

the increase of readings of the voltmeter:

• Headlamp

• Air conditioning

• Back window defroster

INSPECTION OF GENERATOR

Warning lamp of generator

1. Confirm that the battery has been fully charged;

● If it necessary, the battery should be charged.

2. Confirm the accuracy of deflexion and tension values of the wedge type belts.

● If it does not comply with the requirement, then replace it with a new type of wedge type

belt.

3. Turn on the ignition switch, and inspect the generator warning lamp to see whether it is

indicating.

● If it does not comply with the specified requirement, then inspect the generator warning

lamp, or check whether the generator connectors are connected firmly.

4. Confirm whether the generator warning lamp is off after the engine is turned off.

● If it does not comply with the requirement, then inspect the instrument connector to see

whether they are connected properly; if the instrument is malfunction free, then you need
to further inspect the generator itself to see whether there is any short circuit.
