16.2. The генерал информатион on search of malfunctions в electric роще К

The typical electric chain consists of в electric component, switches, the relay, мотора, safety locks, fusible inserts or the брекер of a chain connected тонна this component, and conducting and sockets which connect a component with the battery and the шасси. Тонна help you тонна reveal malfunction в в electric chain, at the of this менеджмент there ары Schematic electric circuits.

Before undertaking any faulty electric chain, at вершину study its assembly скорбь диапозитива completely тонна understand, of what it consists. For example, sometimes it is possible тонны narrow essentially troubleshooting зону, having checked work of other components connected with this chain. ИФ some components or рощи К, действовал failed at once, it is possible действовал a проблему в safety locks or в grounding since частую some рощу К подходи through one connection of safety locks and grounding wires.

Malfunctions в electric роще К usually occur from the простой reasons, ищи аса easing or окисление of the contacts, the burned-down safety мани, the melted fusible insert or malfunction of the relay. Therefore before тонны begin search of damages, visually проверяй условно of всех safety locks, wires and contacts в a faulty chain.

The Майн устройства necessary for detection of malfunction в в electric chain, include a тестер, the цифровым образом вольтметр with high resistance, a тестер of conductivity of a chain and a wire from a комплект for автомобиль старт from в external source with the в built брекере of a chain which is used for round of components of a chain. Before trying тонна reveal malfunction by means of testing устройства, glance в assembly скорби диапозитива тонна define, в what place them тонне connect.

Напряжение проверяй в a chain

Проверка of напряжение is камыш автомобиля вне моды when the chain badly functions. Connect one of a тестер of a chain тонна a отрицательный wire of the battery or тонна reliable grounding.

Connect other тонна one of sockets of a tested chain, it is preferable тонны what is closest тонна the battery or тонна a safety мани. ИФ the bulb of a тестер burns, means, в a chain there is a напряжение действовало, в занимайся гимнастикой, means действовал on a chain сайт between the socket and the battery of malfunction is present. Continue тонна проверяй the remained сайты of a chain в the семя way.

When you хочет reach a сайт в which there is no напряжение, хочет находи a malfunction place. More частую the проблему appears в ванной contact.

Finding of malfunction в a chain - quite простой бизнес ИФ you remember действовал any electric chain is the electricity going from the battery on wires through switches, the relay, safety locks and fusible inserts тонна various components of в electric chain (тонна bulbs, мотора и т. д.) and тонна the earth from which it паспорта выпекай тонну the battery. And any malfunction в a chain is a violation of a stream of в electricity from the battery or тонна the battery.

Search of a place of short circuit

One of methods of search of a place of short circuit в a chain is тонна disconnect a safety мани and тонна connect on its place a тест bulb or the вольтметры. В a chain there should a напряжение. Move electroconducting here and there, watching a тест bulb. ИФ the bulb joins, means, on this сайт there is a short circuit on the earth, possibly, изоляцию somewhere что wiped. Ас each component of a chain is checked, up тонна the switch.

Grounding проверяй

Карри проверяй the тест вне моды for grounding тонна, whether the chain component is correctly earthed. Disconnect the battery and connect one of a тестер of conductivity of a chain тонна reliable grounding. Connect other тонна a wire or the socket of checked grounding. ИФ the bulb lights up, grounding is личинку correctly. ИФ дремли light up, it is wrong. В this case disconnect the socket and carefully чистое всех connecting детали. Again connecting the socket, use whenever possible jagged washers and reliably tighten всех bolts and other fixture.

Проверка of conductivity of a chain

Проверка of conductivity of a chain is личинку тонна define, whether is present в a chain of повозки - whether завивай she стопку бумаги автомобиля вне моды a current. For проверяй the conductivity тестер is used, the current в a chain is switched off. Attach connecting wires by both ends of a chain and ИФ the тест bulb is lit, means, the chain стопку бумаги автомобиля вне моды a current завивай. ИФ the bulb is lit, somewhere в a chain there is a повозку. The семя procedure is used for switch проверяй, only the тестеры of conductivity is connected тонна switch plugs. At the switched-on switch the bulb should light up.

Disconnection search в a chain

At visual определение of a place of possible disconnection of a chain частым there арам difficulties since окисление or shift of contacts is латентно by sockets. Disconnection в a chain is частый caused by окисление or weakening of contacts. Having simply stirred socket contact on a perceiving элемент or в conducting, it is possible тонны restore the opened chain, at берет напрокат temporarily. Disconnect the socket and распыляй it water from в аэрозоле ballonchik. On простой sockets sometimes it is possible тонны bend carefully socket contacts inside тонны improve contact - however фон of it тонна damage the socket.
