Brief Introduction

1. Power supply system

The power supply system includes accumulator, generator and its adjustor. Generator is the main power supply; the

accumulator is the auxiliary power supply. The generator, parallel with the accumulator, is equipped with the

adjustor, which is used to maintain the voltage of generator stable when the rotating velocity and the load varies.

2. Starting System

Which includes the direct current motor, drive mechanism and control device, etc. its performance is to start the

engine.

3. Lighting system

Which includes various lighting lamps inside and outside of the body and their control device; they are used mainly

to guarantee safety driving in night.

4. Alarming System

Which includes the electric horn, flasher and various service signal indicating lamps, etc. they are mainly used to

guarantee the physical and driving safe when driving.

5. Auxiliary Electric Appliance System

It includes the electric wiper, air-conditioner, recorder and cigarette lighter, etc.

The codes of sockets of socket plugging element are

complied from left to right.

2.

The codes of sockets of socket plugging element are

compiled from right to left.

Remark: all of plugging elements are watched from the in-

wiring direction.

3.

Comparison between plug and socket plugging elements

The plug and socket plugging elements are classified accord-

ing to their in-built socket shape.

(a)

All of plugging element are marked according to the

opening end and are locked at their tops.

(b)

When pulling the plugging element, pull the plugging

element itself instead of wire.

Remark: before pulling the plugging element, check the

plugging element that you want to disconnect first to verify

their classifications.

English letters for wiring colors code:

B =black    Bl =blue   R =red    Br =brown

Lg =reseda V  =purple   G =green    O =orange

W =white    Gr =gray   P =pink  Y =yellow

First letter stands for the basic color, while the second for the

stripe color.

Change of fuse and maxi-fuse

Remark: in case of exchanging the fuse or maxi-fuse, the fuse

or maxi-fuse with same rated current should be used.

Notice:

1.

Before exchanging the fuse or maxi-fuse, all electric

appliances and ignition switches should be turned off

firstly. And the rated current of fuse or maxi-fuse should

not be exceeded.

2.

When disassembling or assembling the fuse, the

disassembly and assembly tools must be used. And they

must be pulled out or plugged in vertically. No bend is

allowed because the bend will make the connecting

terminals depart away, and thus poor connection will

occur. In case the fuse or maxi-fuse is burned, it shows

there is short circuit. In such situation, the systematic

inspection should be conducted by the qualified

technician.

Remark: the disassembly and assembly tools are put on the

protective box cover.

How to make systematic inspection

The inspection order is a simple troubleshooting approach, which is used to check and diagnose the failure on vehicle

when there is part (wiring and plugging elements excluded) failure in the systematic operation or presupposed

system.

Following items should be considered firstly when checking the failure.

 wiring failure

 open circuit or short circuit of electric wiring

 failure in plugging element connection or terminal connection

 failure of fuse or maxi-fuse

Notice:

1.

The inspection is conducted on vehicle when the system is in operation, therefore, security should be

taken into account when checking.

2.

Care should be paid not to make short circuit in the system under the condition that the accumulator is

directly connected, and the applicable voltage should be selected correctly.

Voltage inspection

(a)

Verify the voltage situation at the inspection spots.

For example:

Put the ignition switch at
ON
 position

 Put the ignition switch and SW1 at 
ON
position;

 Put the ignition switch of SW, SW1 and the relay at

ON
 position (SW2 at 
OFF
 position)

(b)

Connect the cathode lead (-) to the normal grounding

place or the cathode terminal of accumulator with the

voltmeter; while connecting the positive lead (+) to the

plugging element or part terminal. Such inspection can

be conducted with the test bubble instead of voltmeter.

Inspection on Conductance and Resistance

(a)

Disconnect the terminal or wire of accumulator to guar-

antee there is no voltage between the inspection sports.

(b)

Connect the two measuring leads of ohmn meter with the

inspection spots.

 Brief Introduction

BE-5

If there is diode in the circuit, connect the two leads in reverse

polar and make another inspection. When the cathode lead (-)

is connected with the positive (+) side of diode, and the

positive (+) lead should be connected with the cathode (-) lead

of diode, the diode should conduct, while the two leads

connected to the reverse polar, the diode should not contact.

Remark: the specification may be not same due to different

testing meter types; therefore, the application instruction for

testing meter should be referred before the inspection.

Check the light emitting diode (LED) according to the same

approach for diode inspection.

Remark:

The testing meter should be used the one with 3V voltage or the

one has larger resistance than that in circuit.

If no suitable testing meter is applied, the voltage of accumu-

lator may be added to check the LED to see whether it is

lighted.

(c)

Use the voltage or ohmn meter with high-impedance

(min voltage of 10 KV) to diagnose the failure in electric

circuit.

Check to see whether there is short circuit

(a)

Tear down the burned fuse and remove all loads from

the fuse.

(b)

Connect the testing bubble at the fuse position;

(c)

Verify the situation of testing bubble position:

For example:

Put the ignition switch of SW at
ON
 position;

Put the ignition switch of SW and SW1 at
ON
 position;

 Put the ignition switch of SW, SW1 and Relay at

ON
 position (which connects with the relay), and put

SW2 at 

OFF
) position (or disconnect the SW2).

(d)

Disconnect or re-connect the plugging elements when

observing the testing bubble. In case the testing bubble

keeps lighting, which shows there is short circuit between

the plugging elements; if the testing bubble extinguishes,

there is short circuit between the plugging elements.

(e)

Shake the trouble wire alongside the body to locate the
