Electric circuit of the switch
On the Passat cars the single-wire scheme of turning on of devices of electric equipment is applied. To plus of power supplies consumers unite a wire, and to minus – through a body of the car or on weight. Such method allows to reduce number of wires and to simplify their installation. Connection with the mass of minus of power supplies reduces wear of metal details of a body because of electrochemical corrosion. In certain cases direct connection of the electric consumer with weight is not enough, and the consumer unites to weight an additional wire of usually brown color.
Supply voltage is brought to most of consumers via the ignition switch. Power-supply circuits of those knots of electric equipment which work can be required under any circumstances are always connected to the rechargeable battery, irrespective of the provision of a key in the ignition lock.
For connection of wires electric sockets with flat contacts are used.
For normal food of consumers the electric chain has to be closed, otherwise in it there will be no electric current, for example, if to the electric motor of a screen wiper positive tension moves, it will not work until its electric chain is not connected to weight. In an electric chain switches, the relay, safety locks, measuring devices, electric motors and other consumers of the electric power can be connected. For the correct connection of consumers of the electric power contacts of electric sockets have the corresponding markings. For simplification of use of the electric circuit separate electric chains are located vertically and numbered. The lower line on the scheme is a mass of the car. Connection with the mass of the car is carried out or directly via the case of the consumer of the electric power or an additional wire. Under the lower line of weight on electric circuits there are coordinates on which, using a key, it is possible to define an electric chain or an element.
Numbers on the electric circuit in black rectangles on the end of a wire show the coordinate on which it proceeds. Also in this coordinate the back link is had.
During the work with the electric circuit it is necessary to know alphabetic and graphic symbol of electric elements.
Interpretation of alphabetic reference of elements
And – the accumulator
In – a starter
With – the generator
D – ignition switch
Е – switch
F – mechanical switch
G – sensor, measuring device
N – a sound signal
J – relay
K, L, M, W, X – lamps, control lamps
N – electromagnetic valves, resistors, switchboards
About – the ignition distributor
Р, Q – spark plugs
R – radio receiver
S – safety locks
V – electric motors
Near alphabetic reference there is a digital designation.
For identification of the relay and control units they are led round by a frame. Lines in a frame represent internal connection in the block.
The white figure in a black square designates number of the relay on the relay block. Figures about the relay designate numbers of contacts of the relay, for example, designation 17/87 demonstrates that figure 17 is a designation of contact on a payment, and figure 87 is a designation of contact of the relay.
Contact 30. At this contact there is always positive tension of the accumulator. The wires connected to this contact have color, red or red with a strip.
Contact 31. The contact connects to the mass of the car a wire of brown color.
Contact 15. On this contact positive tension after inclusion of ignition moves. The wires connected to this contact have color, green or green with a strip.
Contact of X. On contact tension after inclusion of ignition moves, however at inclusion of a starter tension is disconnected. It gives the chance at start of the engine to disconnect consumers of the electric power, unnecessary at this moment. High beam headlamps receive food also from this contact therefore at the turned-on driving beam and switching off of ignition there is an automatic switching to marker lights.
Wires are designated by figures and letters located under them.
Figures designated the section of the conductor in mm2, and letters – its color. If in designation of color of a wire there are several groups of letters, then the first group of letters points to primary color of a wire, and the second – to color of a strip.
On plaits of the wires connected one - or the multicontact socket the combination from figures is added to a letter "T".
T2r = two-contact socket,
= 32 contact I will corrode E32/27 with a connection 27 point.
On the scheme all consumers of current and switches are represented in neutral situation. The changed current characteristic, after impact on the switch, is interpreted on the example of the two-level switch, see rice. Electric circuit of the switch.
At turn of the switch in the first situation, current proceeds from contact 82 to contact 83. The second section to la's pereklyuchata is also established in average situation, however does not close contacts. Only at turn of the switch in the second situation current begins to proceed from contact 82 to contact 84 and comes further to the scheme. At the same time due to internal connection, current also continues to proceed from contact 82 to contact 83.
