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

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 dashboard.

PERFORMANCE ORDER

1. For the purpose of ensuring 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 dashboard. The scheme of placement of safety locks in the assembly block is presented on an illustration the Scheme of placement of safety locks in the assembly block located under the dashboard.

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 burned-down current-carrying crossing point.
5. For safety lock replacement previously disconnect the corresponding contour.

6. Open a cover of the assembly block, grasp the case of the beaten-out safety lock the special nippers which have been usually fixed in the block, and pull it vertically up, 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 establishing a new safety lock instead of burned 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) loading. The extremely vicious practice is restoration of the failed safety lock by a peremykaniye of its contacts by means of a metal foil.

At knocking-out of safety locks of maxi address on car repair shop.

9. Pay attention that it is always easy to determine settlement force of any safety lock by color of its case:

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

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 of VV of tension;
   b) Formations of the logic chains working on several, arriving from various sources to entrance signals;
   c) Food shutdowns 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 ensuring 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 dashboard). 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 the relevant system - the serviceable relay when giving food on it should publish distinctly heard click. If click is distributed, means, a cause of failure is malfunction of actually working component, or electroconducting failure. Otherwise, or violation 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 of the obviously serviceable. Thus it is worth to remember that external similarity of two relays not so surely is a guarantee of identity of a principle of their functioning.
2. For relay replacement, first of all, switch off the corresponding electric contour. Then the relay can be easily removed from the seat by a pulling way from a landing nest. Establish to the place of the removed relay new, with the corresponding working parameters.
