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 Current service).
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.
