Safety locks have such design that at reaching certain (on a current strength) an overload in a contour their contact crosspiece fuses values, disconnecting thereby a chain and stopping current circulation in it. Short circuit (Search of causes of failures of an electric equipment see) appears the reason of such overloads more often.

The main safety locks and the relay are collected in the uniform assembly block equipped with a cover and established at the left under the panel of devices.

PERFORMANCE ORDER

1. For the purpose of providing of access to safety locks turn on a turn quarter a fixing clamp and lower a cover of the assembly block, having separated it from the panel of devices. The scheme of placing of safety locks in the assembly block is presented on an illustration the Scheme of placing of safety locks in the assembly block located under the panel of devices.

2. The additional assembly block is established in an impellent compartment, behind the storage battery.

3. The scheme of an arrangement of safety locks in the additional assembly block located in an impellent compartment is presented on an illustration.
4. The failed safety lock is easy for identifying on the melted off or burnt down current-carrying crosspiece.
5. For safety lock replacement preliminary disconnect a corresponding contour.

6. Open a cover of the assembly block, grasp the case of the beaten out safety lock the special nippers usually fixed in the block, and pull it vertically upwards, taking out from plugs of the holder.

7. In the assembly block special "deaf" nests for storage of spare safety locks are provided.
8. Before to establish a new safety lock instead of burnt down, try to establish the reason of a taking place overload and to eliminate it. At all do not replace the beaten out safety lock calculated on higher nominal (on a current strength) loading. The extremely vicious practice is restoration of the failed safety lock by перемыкания its contacts by means of a metal foil.

9. Pay attention that settlement force of any safety lock is always easy for defining on colour of its case:

Colour of a safety lock	Settlement a safety lock a current strength
The orange	5А
The red	10А
Dark blue	15А
The yellow	20А
Transparent or white	25А
The green	30А

The relay

On the design of the relay - an essence the switch working on an electric signal. Usually relays are used for:
   a) Remote inclusion of giving ВВ of pressure;
   b) Formations of the logic chains working on several, arriving from various sources to entrance signals;
   c) Switching-off of a food after control time (in timers).

The majority of relays used on the car are placed in a back part of the main assembly block of safety locks (for providing of access to one relays to uncover the assembly block enough, in other cases it is necessary to remove a carpet upholstery, or the bottom section of furnish from the driver's party of the panel of devices). The relay of the electromotor of a drive of a back screen wiper is placed at a door of a back and located under the panel of its internal upholstery. On some models additional relays are placed in the assembly block of safety locks located in an impellent compartment (see above).

PERFORMANCE ORDER

1. If there are suspicions that refusal any of electric contours is connected with failure of the relay of its management, include corresponding system - the serviceable relay at giving on it of a food should publish distinctly heard click. If click is distributed, means, a cause of a failure is malfunction of actually working component, or electroconducting failure. Otherwise, or infringement of giving of a food takes place, or the relay is faulty actually. Check of a condition of the relay is made by substitution on its place obviously serviceable. Thus it is not necessary to forget that external similarity of two relays not so necessarily is a guarantee of identity of a principle of their functioning.
2. For relay replacement, first of all, switch off a corresponding electric contour. Then the relay can be easily removed from the seat by вытягивания from a landing nest. Establish to the place of the removed relay new, with corresponding working parametres.
