The electric scheme of the switch
On cars Passat the single-wire scheme of inclusion of devices of an electric equipment is applied. With plus of power supplies consumers incorporate a wire, and to a 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 weight of a minus of power supplies reduces deterioration of metal details of a body because of electrochemical corrosion. In certain cases it is not enough direct connection of the electric consumer with weight, and the consumer incorporates to weight an additional wire of usually brown colour.
Pressure of a food is brought to the majority of consumers through the ignition switch. Feed circuits of those knots of the electric equipment which work can be demanded under any circumstances, are always connected to the storage battery, irrespective of position of a key in the ignition lock.
For connection of wires electric sockets with flat contacts are used.
For a normal food of consumers the electric chain should be closed, otherwise in it there will be no electric current, for example, if to the screen wiper electric motor positive pressure moves, it will not work until its electric chain will not be 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 correct connection of consumers of the electric power contacts of electric sockets have corresponding marks. For simplification of using by the electric scheme separate electric chains are located vertically and numbered. The bottom line on the scheme is a weight of the car. Connection with weight of the car is carried out or is direct through the case of the consumer of the electric power or an additional wire. Under the bottom line of weight on electric schemes there are co-ordinates on which, using a key, it is possible to define an electric chain or an element.
Numbers on the electric scheme in black rectangles on the wire end show co-ordinate on which it proceeds. Also in this co-ordinate there is a return reference.
At work with the electric scheme it is necessary to know an alphabetic and graphic designation of electric elements.
Decoding of a letter designation of elements
And – the accumulator
In – a starter
With – the generator
D – the ignition switch
Е – the switch
F – the mechanical switch
G – the gauge, the measuring device
Н – a sound signal
J – the relay
K, L, M, W, Х – lamps, control lamps
N – electromagnetic valves, resistors, switchboards
About – the ignition distributor
Р, Q – spark plugs
R – a radio receiver
S – safety locks
V – electric motors
Near to a letter designation there is a digital designation.
For identification of the relay and blocks of management they are led round by a framework. Lines in a framework represent internal connection in the block.
The white figure in a black square designates relay number on the relay block. Figures about the relay designate numbers of contacts of the relay, for example, the designation 17/87 testifies that figure 17 is a designation of contact on a payment, and figure 87 is a designation of contact of the relay.
Contact 30. On this contact always there is a positive pressure of the accumulator. The wires connected to this contact, have red or red colour with a strip.
Contact 31. Contact incorporates to weight of the car a wire of brown colour.
Contact 15. On this contact positive pressure after ignition inclusion moves. The wires connected to this contact, have green or green colour with a strip.
H.Na's contact contact moves pressure after ignition inclusion, however at inclusion of a starter pressure is disconnected. It gives the chance to disconnect at engine start consumers of the electric power unnecessary at this moment. Headlight headlights receive a food also from this contact, therefore at the included headlight and ignition deenergizing there is an automatic switching on dimensional fires.
Wires are designated by figures and the letters located under them.
Figures designate conductor section in мм2, and letters – its colour. If in a designation of colour of a wire there are some groups of letters the first group of letters specifies in primary colour of a wire, and the second – on colour of a strip.
On plaits of wires connected one- or a multicontact socket to the letter "Т" is added a combination from figures.
Т2р = a two-contact socket,
Е32/27 = 32 contact socket with a point of connection 27.
On the scheme all consumers of a current and switches are represented in neutral position. Changed токовая the characteristic, after influence on the switch, is interpreted on an example of the two-level switch, fig. the Electric scheme of the switch see.
At switch turn in the first position, a current proceeds from contact 82 to contact 83. The second section переключате ля also is established in average position, however contacts does not close. Only at switch turn in the second position the current starts to proceed from contact 82 to contact 84 and arrives further in the scheme. Thus at the expense of internal connection, the current also continues to proceed from contact 82 to contact 83.
