Location of fuses, fuse links and relays and their replacement
Most of the vehicle's electrical power circuits are protected by fuses. Lights, fan motors, fuel pump and other powerful consumers are connected via relays. Fuses and relays installed in mounting blocks which are inside the vehicle instrument panel in the end to the left side, the left side front section and in the engine compartment on the left of the battery.

Most of the fuses installed in the mounting fuse box in the passenger compartment (Fig. 10.1) located on the front of the body side under the plastic cover. Circuit protected by fuses (fuse numbers shown in the photo), are shown in Table. 10.1.

In addition, relays and fuses are located in the mounting block in the engine compartment (Fig. 10.2 and 10.3, the mounting block lid removed). Table. 10.2 Specified appointment set fuses, fuse links and relays, but on a particular model of car may be missing some of the circuitry shown in the table.

3. Before replacing a blown fuse, find out the cause of his burnout and eliminate it. When troubleshooting, check indicated in Table. 10.1 circuit that protects the fuse.
A WARNING Do not replace fuses jumpers or fuses, designed for a different current, and improvised jumpers - this can cause damage to electrical appliances and even a fire. |
4. Remove the replaceable fuse. 5. It looks like a blown fuse (arrow jumper inside the plastic holder and burned parted). To replace a blown fuse with a spare fuse of the same value (and color).
NOTE Spare fuses of different denominations are located on the back cover of the assembly block of the relay and fuses installed in the engine compartment. |

HELPFUL HINTS Before you start working on troubleshooting a circuit, carefully study the corresponding scheme that as clearly as possible to imagine its functionality. Circle troubleshooting usually by gradually narrows the definition and exclusion of well-functioning elements of the same circuit. With the simultaneous failure of several elements or outlines the most likely cause of failure is a blown fuse or a violation of the relevant contact with "weight" (different circuit in many cases may be closed by one fuse or earth terminal). Electrical failure is often explained by simple reasons, such as corrosion of the connector pins, failure of fuses, blown fuse, or damage to the relay. Visually check the condition of all safety locks, wires and pin connectors circuit before proceeding to a more detailed inspection of serviceability of its components. In the case of applications for troubleshooting diagnostic tools, plan carefully (according to the wiring diagrams), in which the point of the circuit and the sequence in which the device must be connected to most effectively detect faults. The main diagnostic devices include electrical circuits tester or voltmeter (you can use a 12-volt test light with a set of connecting wires), LED open circuit (probe), which includes a lamp, its own power supply and a set of connecting wires. In addition, you should always have a set of wires in the car to start the engine from an external source (other car battery) equipped with terminals of type "crocodile" and preferably a chopper circuit. They can be used for bridging and connecting various electrical components in the diagnosis circuit. As already mentioned, before proceeding to checkout circuit using the diagnostic equipment, identify schemes where it is connected. One way to find the short circuit is to extract the fuse and wiring instead lamp or voltmeter probe. The tension in the chain should be absent. Pulled wiring, watching the lamp-sampler. If the light starts blinking, somewhere in the wiring harness is the closure of the "masses" may have caused grinded wire insulation. A similar test can be carried out for each of the components of the electric circuit by incorporating the respective switches. When the diagnosis is suspected of having an open section of the circuit to visually detect the cause of the problem is rather difficult, as is difficult to visually check the appearance of corrosion on the terminals or a violation of the quality of their contacts due to limited access to them (normally closed terminal connector housing). Sudden twitching body harness pads on the sensor itself, or harness in many cases leads to the restoration of contact. Keep this in mind when trying to localize the causes of failure of the chain, the suspect in the presence of a cliff. Instability arises failures may be due to oxidation of the terminals or violation of the quality of contacts. |
