Due to limited space, it is not possible to include in this manual the wiring diagrams of the electrical equipment systems of all models under consideration. For this reason, only the most typical diagrams are given below, allowing you to understand in detail the principle of operation of the main electrical equipment systems and on-board electrical consumers.
Before diagnosing the failure of any of the circuits, check the condition of the fuses and circuit breakers protecting it (if the latter are provided). Make sure the battery is fully charged and check the quality of the contact connections of the wires coming from its terminals (see chapter Settings and ongoing maintenance).
When looking for a failure of a particular circuit, first of all also check the quality of the contact connections of its electrical wiring. When disconnecting electrical connectors, try to pull only by their housings, and in no case by the wiring harness.
