10.7. Onboard electric network

Sources and the consumers of electric energy established on the car, incorporate among themselves an onboard electric network. Basic elements of an electric network are connecting wires, means of protection of chains from overloads and short circuits, means of switching (switches and switches) both various connecting and switching centers.
Design and functions of a part of elements of an electric network of the car are considered above at the description of concrete products and systems. In this section missing information is provided.

For protection of knots of electric equipment and electroconducting against overloads and short circuits the fuses of plug type established in assembly blocks are used. The block located in salon of the car under facing of the left part of the dashboard (fig. 8.17), includes the safety locks listed in tab. 8.7.
