Attention! All switches and contacts are in a mechanical non-working position.
- 1. Terminal designation, 15: battery voltage applied with ignition on
- 2. Internal connections (fine strokes). These connections are not conductors. And yet they conduct current and allow you to trace the direction of the current inside the device
- 3. Designation of contacts on the relay / control unit and on the relay board / additional relay board, for example: 17/ 87 - on the relay board
- 4. Relay location number: indicates the location of the relay on the relay board or optional relay board
- 5. Cross section of the conductor, mm2
- 6. The color of the conductor corresponds to the color of the conductor in the machine, here: green/white
- 7. Designation of parts: according to the legend, they find the name of the device conventionally indicated on the diagram (here is the coolant fan)
- 8. Designated part, the symbol of which is in the electrical circuit above 9. Circuit number, to facilitate finding the device in the electrical circuit
- 10. "Weight" car (common wire of the power supply system)
- 11. The numbers in the circles indicate the location or location of the ground connections
- 12. The combination of letters and numbers indicates plug connections, where T4 is a four-pin plug connection. Deciphering the designation of the plug connection: T14 / 12 - means: 14 - pin plug connection, 12 - pin No. 12 in the connection
- 13. Circuit designation: reversing light switch
- 14. The numbers in the squares indicate: a break in the conductor and indicate in which circuit it continues
- 15. Combination of letters and numbers on the connections: the occupancy of the line by conductors of multi-pin or individual plug-in connections is indicated, for example B15a - multi-pin connection B, pin 15a.
- 16. Field: indicates the relay board with fuses
