16.5. General information on safety locks

Electric chains of the car are protected by a combination of safety locks, breakers of a chain and fusible inserts. The block of safety locks settles down under the dashboard on the left side, in electroconducting. Latest models are equipped with also service center close to the block of safety locks, and containing certain components, such, as the relay of a horn and an emergency signal.

Each safety lock is established to protect the separate chain which, it is specified on the panel of safety locks.

Tiny safety locks are mounted in the block. These safety locks of "knife" type, it is convenient to take out and replace them with finger-tips. At violation of work of any component of a chain always at first check a safety lock. It is easy to define burned-down safety lock visually: via its transparent case it is possible to see any damage. If there will be a need to inspect conductivity of a chain, tips of "knife" plugs are easy for finding on the safety lock case.

At replacement of a safety lock make sure that the type of a new safety lock corresponds to the burned down. Physically all safety locks are interchangeable, but it is necessary to use only that type which is required. It is not recommended to establish safety locks of bigger or smaller value since each electric chain needs certain extent of protection. Value of a current of each safety lock is designated on its case.

If the replaced safety lock fuses at once, do not replace it again while the cause of defect is not revealed and it is not eliminated. In most cases the reason is short circuit in the conducting, caused by the worn-out or broken wire.
