CIRCUIT 

 

Compiling Explanation   
 

1.    Central Electrical Box Main Circuit Board Circuit No.   

        30：No Fuse, Positive Goes Directly From Battery 

        15：No Fuse, Positive Goes To Ignition----Start Switch   

        X：No Fuse, Positive Goes To Ignition ----Start Switch, And Being Cut Off During Starting 

31：Fictitious

 

Ground, This wire actually exists or does not actually exist. 

Example: 30(E8) defines these 30 hot wires are directly from battery, and come from central 

electrical box socket E pin No. 8.   

30(C16)、15(D10)、X(D12)…are similar as 30 (E8) 

2.      Central Electrical Box Main Circuit Board Block 

          This block on main circuit board includes fuse, relay and connection interface. 

3. 

Wire routes as follows: 

          ——coming from right side on previous page 

——going to left side on next page   

4.      Central Electrical Box Main Circuit Board Pins No. 

It will be helpful for locating main circuit board circuit, such as E/8 indicates the 8

th

 pin on central 

electrical box socket E. 

5.      Wire colors and cross-area, square millimeter 

6.   Connection Symbol 

This symbol is signed on component. 

7.      Parts or components name (illustrated on left bottom of each page). 

8.   symbol for wire continuing  

Number in square form indicates wire number or appropriate extending wire no.   

9.   Internal wire 

          Used for locating internal wire. This wire may actually exist or does not exist.   

10.  Ground point 

          Indicated by number in circle, and the point is also indicated on circuit. 

11.  Circuit number 

          Used to locating component and interrupted wire connecting point. 

12.    Multi-hole connector connecting points 

     Socket terminal numbers are given.
