GENERAL INFORMATION

Fuses

Arrangement of safety locks and the relay on the dashboard on the SRi model of 2,0 l

Removal of the fuse on models of 2,0 l

Fuses are intended to break off a chain when current in a chain exceeds admissible value.

Fuses are placed in the block of safety locks and the relay located under a cover from the lower right side of the dashboard (see rice. An arrangement of safety locks and the relay on the dashboard on the SRi model of 2,0 l). The arrangement of safety locks and electric chains protected by safety locks are given in inside on a cover of the block of safety locks and the relay.

Before removal of a safety lock switch off ignition. To remove a safety lock, just take it from the socket (see rice. Removal of the fuse on models of 2,0 l). The wire in a safety lock is swept easily up and will be broken off if the safety lock fused.

Always replace a safety lock with other safety lock of the same power. Each safety lock has an inscription about the size of the protected current. Never replace a safety lock more than once, without having defined the reason of its burn-out.

Relay

Relay block arrangement in a motor compartment on the SRi model of 2,0 l

The relay is an electronically controlled switch which is usually used as follows:

– the relay can switch big currents remotely from a chain in which this current flows, allowing to use thinner wires and contacts of switches;
– the relay can have more than one managing director of an entrance, unlike механичес whom the switch;
– the relay can perform function of the timer, for example, to set an interval of work of screen wipers.

If the system operated by the relay fails also a cause of defect, perhaps, the relay is, listen to operation of the relay at the included system. If the relay regularly works, then you have to hear click at its inclusion. If the relay is serviceable, then the cause of defect is concluded in elements or the connecting wires. If the relay does not work, it means that it does not receive the main power supply or the operating impulse, or the relay is faulty.

For replacement of the relay switch off ignition and, having just pulled the relay, take it from a nest and insert on its place new.

The most part of the relay is located from a reverse side of the main block of safety locks. For access to the relay unscrew screws and take the block of safety locks, moving it forward. The relay of a back screen wiper is located in a back door behind the upholstery panel.

On some models additional relays are located in the relay block installed on the left side of a motor compartment (see rice. A relay block arrangement in a motor compartment on the SRi model of 2,0 l).
