Search of causes of failures of an electric equipment
The general data
The typical electric contour consists of the electric power consumer (a working component), a set of switches, the relay, executive electromotors, safety locks, the fusible inserts/breakers of the chain concerning work of the given component, and also connecting electroconducting, its contact plugs and sockets. For the purpose of simplification of performance of diagnostic procedures in last Section of the Scheme of electric connections schemes of electric connections of various systems of an electric equipment of the car are resulted.
Before to start search of causes of a failure of the failed consumer of the electric power, attentively study the corresponding electric scheme, try as it is possible to imagine more clearly a principle of functioning of the components which are a part of the suspected contour. The list of possible causes of a failure can be shown to a minimum by an exception of it of regularly functioning components concerning work of the checked contour. At simultaneous infringement of functioning at once several components, most a refusal plausible reason is failure of the general for corresponding chains of a safety lock / a fusible insert, or grounding infringement.
More often electric equipment refusals speak the elementary reasons, such as damage by corrosion, or fastening easing клеммных connections, failure of a safety lock or a fusible insert, relay refusal, etc. Before to start search of internal defects of actually refused component, attentively check up a condition of all safety locks concerning its functioning, sockets and connecting wires. For definition of the list of knots subject to check and клеммных connections, study the corresponding scheme of electric connections.
To number of the diagnostic tools necessary by search of refusals of an electric equipment, it is necessary to carry a universal measuring instrument of a chain/voltmeter (for some checks 12-voltnaja the lamp with the complete set of connecting wires also will approach), a lamp-sampler with the individual power supply (sometimes named also a conductivity measuring instrument), an ohmmeter, the power supply with the complete set of connecting wires, and also a set of the wires-crosspieces, equipped various type connecting plugs and, - it is desirable, - the built in breaker of a chain or a safety lock (for shunting of suspicious sites of a chain or electric components). Before to resort to use of the diagnostic equipment attentively study the scheme of electric connections of components of a corresponding contour (the Section of the Scheme of electric connections see).
The elementary check of a chain which are carried out by twitching of various sites of electroconducting of the corresponding contour in which result the defective piece of a chain is localised can be made for search of the reason of refusal having astable character (infringements such usually appear connected with oxidation of contact plugs, or fastening easing клеммных electroconducting connections). The given check can be made together with any of listed more low in corresponding subsections.
Except the problems connected with infringement of quality of electric connections, it is necessary to carry breakages and short circuits to number of the most probable and often occurring refusals of electric contours in a chain.
Chain breakage is usually caused by mechanical damage токопроводных veins or a detachment of contact plugs that leads to disconnection of an electric contour and the circulation termination in it of an electric current. As a result of chain breakage its working component ceases to function, however corresponding safety locks / fusible inserts do not fail.
As short circuit is called unforeseen a design of a chain short circuit of its electroconducting. Thus the current starts to circulate on the shortest way, usually leaving on weight. Short circuits appear connected with infringement of integrity of isolation of electroconducting more often and without fail lead to failure of corresponding safety locks / fusible inserts.
Pressure stock-taking in a chain
Search of the reasons of short circuit
Search of infringements of grounding
The negative plug of the battery is earthed on "weight" in which quality metal of the power unit, the chassis and кузовных car elements acts. Electric contours большей electric equipment parts are constructed in such a manner that electroconducting is used only for food giving to the consumer from the positive plug of the battery, return of a current to the battery is carried out on weight metal. Told means that fixing elements of consumers of the electric power form themselves a returnable part of an electric chain. In view of the described situation, easing of fastening or corrosion of basic elements of a working component of a chain involves infringement of serviceability of functioning of a contour (from a full exit of the last out of operation before partial refusal of various sites of a chain). In particular, as a result of fixture easing brightness of a luminescence of lighting devices (in particular in the presence of the general grounding with other contour), or speed of rotation of the electromotor (for example, a drive of screen wipers or the fan of system of cooling) can decrease. Thus refusal of one contour can cause infringement of functioning of the another which outwardly in any way have been not connected with failed. Pay attention that on many cars certain knots are connected among themselves by special tyres of grounding. Such tyres are used when there is no direct contact of metal parts of blocks in view of the equipment of support flexible rubber plugs (as, for example, in support of fastening of the power unit to the car chassis).
Search of breakages of a chain
Astable refusals of consumers of the electric power appear connected with quality infringement клеммных connections at the expense of oxidation or fixture easing more often. Often for component reduction in a working condition, it appears to pull simply enough a corresponding plait of electroconducting / an electric socket. The most simple way of search of breakage of a chain is check of its working sites on conductivity presence. Disconnect power supplies of a contour and take advantage of the equipped independent power supply a measuring instrument. Connect measuring instrument wires to both exits of a checked chain (the plug of giving of a food and well earthed point). If the device fixes conductivity presence (zero resistance/operation of a lamp-sampler), hence, the checked site of a chain is serviceable. Breakage otherwise takes place. In the similar way serviceability of functioning of switches can be checked up.
Electric sockets - the general data
The majority of contact sockets of chains of an onboard electric equipment are made of plastic and are multicontact. Reliability of a joint of half of such sockets is provided защелкиванием lock uvulas of the clamps built in in tips. Large sockets, such as some of the devices of the car located under the panel, are fastened passed through the central part of tips by through bolts more often.
For рассоединения the sockets equipped with plastic clamps the small screw-driver to which should wring out accurately lock uvulas (preliminary attentively usually is used study a design of the joined socket - often to measure a way of fixing of its half by eye completely not simply; some sockets are equipped by several lock knots). Pull only for the tip, and at all for an electroconducting plait, in order to avoid casual damage of the contact plugs built in in a socket.
Sockets always consist of two half plugs of one of which enter in plugs another. At studying of schematic images of sockets try to define first of all what of its half it is presented on an illustration - connected to a plait, or fixed on a component. Remember that plugs of one half of socket always are placed mirror in relation to plugs another.
Often, at a problem diagnostics of electric chains there is a necessity of check of pressure on plugs of the joined socket. At such checks щуп a measuring instrument it is entered into the corresponding plug from the back party of the tip. Be careful, try not to bend and not to deform plugs. If nests of plugs are too small, take advantage in quality щупа of the unbent metal writing paper clip to which then it is possible to connect a wire of a measuring instrument by means of a clip of type a crocodile.
