10.2.1. Arrangement of safety locks, fusible inserts and relay and their replacement

The majority of power-supply circuits of electric equipment of the car is protected by fuses. Headlights, electric motors of fans, the fuel pump and other powerful consumers are connected via the relay. Safety locks and the relay are installed in assembly blocks which are in interior of the car in a dashboard end face on the left side, on the left forward part of a sidewall and in podkapotny space to the left of the rechargeable battery.

The majority of safety locks is installed in the assembly block of safety locks in salon (fig. 10.1) located on a forward part of a sidewall of a body under a plastic cover. The chains protected by safety locks (numbers of safety locks are specified a photo), are given in tab. 10.1.

Besides, the relay and safety locks are located in the assembly block in podkapotny space (fig. 10.2 and 10.3, the assembly block is uncovered). In tab. 10.2 purpose of the established safety locks, fusible inserts and the relay is specified, but on concrete model of the car there can be no chains specified in the table.

Relays are located also in a dashboard end face on the left side of (fig. 10.4, for descriptive reasons on a photo removed facing of the dashboard). In tab. 10.3 purpose of the relay is specified.
1. For receiving access to the assembly block of safety locks squeeze a clamp …
2. … also uncover in facing of a forward part of a sidewall.

The table 10.3 Purpose of Safety Locks and Fusible Inserts in the assembly block located in the dashboard

    
NOTE
On inside of a cover the scheme of an arrangement of safety locks is put.

3. Before replacing the fused safety lock, find out the reason of its burn-out and eliminate it. When troubleshooting see the chains specified in tab. 10.1 which are protected by this safety lock.

    
PREVENTION
Do not replace safety locks with the crossing points or safety locks calculated on other current and self-made crossing points – it can lead to damage of electric devices and even to the fire.

4. Take the replaced safety lock.
5. So the fused safety lock looks (the crossing point shown by an arrow in the plastic holder fused and was opened). For replacement of the fused safety lock use a spare safety lock of the same face value (and colors).

    
NOTE
Spare safety locks of different face values are located on a reverse side of a cover of the assembly block of the relay and safety locks installed in a motor compartment.

6. For access to the assembly block located in a motor compartment take a steam discharge hose of the cooling system from the holder on a cover of the assembly block and take him aside …
    
NOTE
The scheme of an arrangement and purpose of safety locks, fusible inserts and the relay in the assembly block is applied on a cover.

7. … wring out two clamps of a cover on each side …
8. … also uncover the assembly block.
9. In need of replacement take the relay (safety lock), shaking it here and there.
10. For replacement of the main safety lock No. 1 (see fig. 10.2) turn out two bolts …
11. … also remove a safety lock.
12. For access to the assembly block of the relay located in the dashboard hook the screw-driver …
13. … also open a cover in a dashboard end face.
14. In need of replacement take the relay from the assembly block, shaking it here and there (on a photo facing of the dashboard is for descriptive reasons removed).
15. Establish details as it should be, the return to removal.

    
USEFUL TIPS
Before getting to work on elimination of malfunctions in any electric chain, attentively study the corresponding scheme as much as possible to have a clear view of its functional purpose. The circle of troubleshooting is usually narrowed due to gradual definition and an exception of normally functioning elements of the same contour. At simultaneous failure of several elements or contours burn-out of the corresponding safety lock or violation of contact with "weight" is the most probable cause of refusal (different chains in many cases can become isolated on one safety lock or a conclusion of grounding).
Failures of electric equipment often are explained by the elementary reasons, such as corrosion of contacts of sockets, failure of a safety lock, burn-out of a fusible insert or damage of the relay. Visually check a condition of all safety locks, conducting and contact sockets of a chain before starting more detailed check of serviceability of its components.
In case of application for troubleshooting of diagnostic units carefully plan (according to the enclosed electric circuits) in what points of a contour and in what sequence it is necessary to connect the device for the most effective detection of malfunction.
The tester of electric chains or the voltmeter (it is possible to use also a 12-volt control lamp with a set of connecting wires), the indicator of break of a chain (sampler) including a lamp, own power supply and a set of connecting wires are among the main diagnostic units. Besides, it is always necessary to have in the car a set of the wires for launch of the engine from a foreign source (the rechargeable battery of other car) equipped with clips like "crocodile" and it is desirable the breaker of an electric chain. They can be applied to shunting and connection of various elements of electric equipment at diagnostics of a chain. As it was already mentioned before starting check of a chain by means of the diagnostic equipment, determine by schemes of the place of its connection.
One of methods of search of short circuit is extraction of a safety lock and connection instead of it of a lamp sampler or the voltmeter. Tension in a chain has to be absent. Pull conducting, watching a lamp sampler. If the lamp begins to blink, somewhere in this plait of wires there is a short circuit on "weight", perhaps, caused by a mastication of isolation of wires. A similar inspection can be carried out for each of components of an electric chain by turning on of the corresponding switches.
At diagnostics of the suspect available of break of the site of an electric chain visually to find a cause of defect it appears to check quite difficult as happens hard visually plugs for emergence of corrosion or violation of quality of their contacts because of limited access to them (usually plugs are closed by the case of the contact socket). Sharp twitching of the case of a block of a plait of wires on the sensor or the plait of wires in many cases leads to contact restoration. Do not forget about it in attempts of localization of a cause of failure of the chain suspected available break. Unstably arising refusals can be a consequence of oxidation of plugs or violations of quality of contacts.
