BE-2
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.

1. 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.

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. Body Electric System

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
SW2 electromagnetic
coil
