（l）Entire vehicle electrical system positive power supply is divided into three ways, “30” is

constant power supply line, “30a” which is through the fuse F20（40A）is also constant

power supply, the voltage is 12V, it connect to battery directly, not through any switch, it

always has electricity no matter the car is parking or the engine is turned off , it sends the

power supply to the electric apparatus which need use power when engine is turned off, for

example, parking lamp, alarm light, ceiling lamp and so on; “15”and “15a” is power

supply line for the small capacity electric apparatus; it has electricity only the ignition

switch is on II or III position. “Ka” is a power supply line for radio and cigarette lighter; it

has electricity only the ignition switch is on ACC position. “X” is power supply line for

starter pull-in winding.

（2）“F” stand for fuse, the number follow F stand for the fuse’s place in the central circuitry

board ; For example, F9 means this fuse is in the ninth position of the relay box, the capacity

of the fuse can judge by its color: red is 10A, green is 30A, yellow is 20A, blue is 15A.
