14.3. Safety locks - the general information

The block of the relay and safety locks in an impellent compartment

The part of safety locks is located on considered cars in the assembly block located under a cover at the left end face of the dashboard (see. Specifications and No. 11 on an illustration Components of installation and dashboard fastening). Other safety locks are placed in an impellent compartment, over the storage battery - see an illustration Specifications are higher also.

Each separate safety lock is used for protection of any concrete electric contour or at once several contours.

In assembly blocks the safety locks of a compact design equipped with bayonet contacts, and, if necessary, easily taken by fingers from the nests in the block are used. At refusal any of consumers of the electric power first of all always it is necessary to check a condition of the corresponding safety lock. Include ignition and by means of a lamp sampler probe open plugs of each of safety locks. If the lamp lights up at connection to each of plugs, therefore, a safety lock as it should be. If tension takes place only from food giving, means, the safety lock fused. Let's notice also that usually the case of a safety lock is made of transparent plastic through which it is easy to define a condition of a working crossing point.

At replacement of the fused safety lock strictly watch that the prepared replaceable element corresponded on type failed. The safety locks calculated on a various nominal current physically can differ nothing from each other, without being thus interchangeable. Each of electric chains has various working parameters and needs various extent of protection therefore replacement of the safety lock calculated on a certain current, a safety lock with not in the corresponding parameters is fraught with the most serious consequences (up to fire emergence). Working parameters of a safety lock are usually designated on its plastic case, besides, color identification (in addition is used see. Specifications).

If the new safety lock after installation also fails at once, it is not meaningful to make its further replacement, - before it is necessary to reveal and eliminate the reason of emergence of an overload in a chain. In most cases that appears the short circuit of connecting electroconducting caused by damage of its isolation. Spare safety locks usually are located in free blocks of the assembly block.
