Work with electric circuits The possibility of definition of malfunction or additional installation of electric devices requires existence of electric circuits. The electric chain has to be surely closed. There is not enough, for example, if to the positive plug (+) headlights tension is brought, and other plug(s) is not closed on weight. Therefore the cable of mass of the rechargeable battery (-) is connected to weight. In some cases such communication with weight appears insufficiently and the corresponding consumer has a direct connection with a weight. Isolation of such communication has, as a rule, brown color. Separate electric chains can have switches, relay, safety locks, measuring devices, electric motors and other electric elements. That it is correct to attach the specified elements, connecting cables have various colors, and contacts have numbering. For convenience of work with car electric equipment all system is divided into separate chains. The electric elements interacting with each other are shown on the general scheme. As a rule, at the top of the scheme positive contacts (+), and below contacts of weight(s) are given. Connections of weight are carried out usually through a body or through an additional wire from a point of the weight which is available on a body.
Designations of the major plugs: Plug 15. Receives a power supply from the ignition lock. Food moves only at the included ignition. Cables have black color or black with color strips. On the following example rules of reading the electric circuit are shown. 1) Designation of plugs, here plug 30. Designations of the major elements following: A-holder safety lock/device management/module |
