Safety locks

Protection of electric contours of the car is provided with application of a combination of safety locks, breakers of a chain and fusible inserts. The burnt down safety lock is easy for distinguishing from serviceable by survey of its transparent plastic case. Attentively examine a safety lock about its revealing перегорания. If the safety lock outwardly looks normally, but suspicions on its malfunction have remained, make conductivity check between ножевыми the plugs acting from its case.

Перегорание safety locks of this kind can be revealed by visual survey

At replacement of safety locks watch conformity replaceable old on type. The safety locks calculated on a various current strength can outwardly look identical, therefore it is necessary to give special attention to marks. Replacement of the burnt down safety lock on calculated on smaller – and especially big – a current strength is undesirable. Each electric contour requires different degree of protection. Watch that marks on the safety lock case corresponded to a current strength on which the corresponding contour is calculated.

If the replaced safety lock immediately fuses, it is not reasonable to continue its replacement. Before it is necessary to reveal and eliminate its reason выбивания. In most cases that appears short circuit of electroconducting of the contour, caused by breakage or damage of isolation of a wire.
