Safety locks - the general information

Various combinations of safety locks, breakers of a chain and fusible inserts can be applied to protection of contact chains of electric equipment of the car.

Big safety locks (and the relay) is located on considered models of cars in the assembly block located at the left under the dashboard. On the Astra models the assembly block is behind a box for the trifles which facing should be removed previously from the panel, after removal of components of a box it is necessary to pull for the block bottom for the purpose of a conclusion its working situation. On the Zafira models it is enough to open a cover of the assembly block on the dashboard.

The second assembly block of safety locks / relay is located in an impellent compartment of the car, has a separate design and is equipped with demountable covers.

Each separate safety lock is used for protection of any concrete electric contour or at once several contours. The ID card with the scheme of placement of safety locks in the assembly block is usually glued to a cover of the last, from its internal party.

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. Turn a key in the ignition lock in the situation ON 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 by not corresponding to it on parameters is fraught with the most serious consequences (up to fire emergence). Working parameters of a safety lock (a nominal current) are usually designated on its plastic case, besides, color identification (in addition is used see. Specifications).

From the interior of a cover of the assembly block the special clip which use allows to facilitate procedure of extraction of a safety lock considerably can be attached.

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.

On all models of cars considered in the Real Management additional protection of electric equipment by at most eight main safety locks placed in the separate block equipped with a cover, fixed on a wall of the assembly block placed in an impellent compartment is provided.

Knocking-out of any of the main safety locks leads to a de-energization of the most part of electric equipment. Before starting replacement of the main safety locks without fail disconnect the storage battery. Replaceable main safety locks always can be got in a supply division at firm car repair shop Opel.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action! Remember that the failed main safety lock should be replaced with the replaceable calculated on the same current.
