SEN00056-01 00 Index and foreword How to read electric wire code 1 a The information about the wires unique to each machine model is described in Troubleshooting section, Relational information of troubleshooting. In the electric circuit diagram, the material, thickness, and color of each electric wire are indicated by sym- bols. The electric wire code is helpful in understanding the electric circuit diagram. Example: AEX 0.85 L - - - Indicates blue, heat-resistant, low-voltage wire for automobile, having nomi- nal No. of 0.85 Indicates color of wire by color code. Color codes are shown in Table 3. Indicates size of wire by nominal No. Size (Nominal No.) is shown in Table 2.
Indicates type of wire by symbol. Type, symbol, and material of wire are shown in Table 1. (Since AV and AVS are classified by size (nominal No.), they are not indi- cated.) 1. Type, symbol, and material AV and AVS are different in only thickness and outside diameter of the cover. AEX is similar to AV in thickness and outside diameter of AEX and different from AV and AVS in material of the cover.
