Fusible inserts - the general information

Protection of some contours is carried out by inclusion in their electric chain of fusible inserts. Inserts are usually used for protection of the contours which are not equipped with safety locks such as ignition contour.

Fusible inserts on these models are similar to safety locks in the sense that an exit them out of operation (oplavleniye) easily is defined visually.

For replacement of a fusible insert at first disconnect a negative wire from the battery. Take the burned-down insert and establish on its place new (can be acquired in representative office or shop of automobile accessories). Before replacement of an insert surely try to define the reason of the overload which caused its exit out of operation.
