Circuit breakers

To protect the electrical components used several types of fuses.

In cars S40 / V40 are 4 different types of fuses:

1) a large fuse with screw connection (120 A);

2) large flat pin fuses;

3) normal fuses;

4) miniature fuses (only in the cabin).

In block 1 (Fig. 10.2), installed in the engine compartment, there are the following fuses:

1) main fuse starter and alternator (120 A);

2) a few fuses for higher amperage for the subsystems;

3) conventional fuses for different components.

In block 2, established under the dashboard next to the reception are:

1) All fuses located after ignition;

2) several fuses are located directly in the chain of supply.

Some elements of the system are protected by several fuses installed in series.

For example:

Cigarette lighter:

The main fuse (1/1), then the fuse (1/2) Power fuse / relay box under the dashboard, then the fuse (2/13) in the relay interior lighting.
