Electric equipment of the engine

General information

Components of systems of ignition, charge and start are a part of electric equipment of the engine. In view of the fact that these systems have a direct bearing on operation of the engine, they are considered separately from other onboard electric equipment (such as signal and lighting lights, monitors, etc.), the Head Onboard electric equipment is devoted to placement, a design and which principles of functioning. Control of functioning of system of ignition is exercised under control of ECM, - the principles of functioning of a control system of the engine are considered in the Head of the Power supply system and release.

In order to avoid risk of failure of semiconductor elements, and also for the purpose of prevention of receiving eletkrotravm, at service of components of systems of electric equipment it is necessary to observe special precautionary measures. Remember that the generator and a starter are directly connected to the battery and in case of an overload or short circuit can become a cause of the fire. Performing works on service of the components located in a motive compartment, try not to touch moving elements (a krylchatka of the fan, driving belts, etc.), take away hair, clasp working clothes on all buttons.

Starting service of electric equipment, surely remove a watch, rings and other metal jewelry. Even at the disconnected battery the category of condensers at casual grounding of their plugs can lead to receiving electric shock or a strong burn.

Do not allow violation of polarity at connection of the battery. In structure of such components as the generator, electronic control units and so forth enter semiconductor elements which can be put out of action at the wrong connection of wires.

When performing start of the engine from the external power supply, or connection of the charger also observe polarity of connection of wires (see the Sections Start of the Engine from the auxiliary power supply and Removal/installation, check and service of the battery).

Never disconnect an electrical wiring from the battery, the generator or the diagnostic equipment at the working engine.

Do not allow a provorachivaniye the engine of the disconnected generator.

Do not make verification of output tension of the generator by grounding of its plugs at all.

Do not apply to verification of conductivity in a chain the ohmmeters equipped manual with a dynamo car.

When performing any works on service of electric equipment watch that the negative wire was disconnected from the battery.

Before use of arc welding without fail disconnect the battery, the generator and such components, as ECM of systems of food/ignition in order to avoid risk of their damage.
