Arrangement of the main block of safety locks and the relay on the dashboard from the driver

The main block of safety locks and the relay is located under a cover in the dashboard from the driver.

The arrangement of safety locks and the relay is given in a cover.

Each safety lock has an inscription about the size of the passed current.

To remove a safety lock, use tweezers for extraction of a safety lock from the socket. Get a safety lock from tweezers. 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. Never replace a safety lock more than once, without having defined the reason of its burn-out.

Relay

The relay is electronically the operated switch which is usually used as follows:

  – the relay can switch a high-tension current 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 the mechanical switch;
  – the relay can perform function of the timer, for example, to give an interval of work of screen wipers.

Relay arrangement in front of the accumulator in a motor compartment

Relays are located in the main block of safety locks and the relay though some relays connected with the engine are located in a motor compartment.

If the system operated by the relay fails, and 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.
