Circuit breakers
The vehicle's electrical circuits are protected by fuses and circuit breakers (reverse current relay) and fusible inserts. The main fuse/relay box is located in the engine compartment; The design also provides for the presence of an additional unit, which is located in the cabin under the left rear seat and (see illustrations).
3.1a. The main fuse/relay box is located in the engine compartment on the bulkhead; release the retaining tabs and remove the outer cover

Each fuse is included in a specific circuit. The matching diagram of fuses and circuits is shown on the block.
The blocks are equipped with fuses of several sizes: miniature, medium and large. Fuses of all sizes have a similar design. Medium and large safeties are removed by gripping with your fingers. Miniature fuses must be removed using pliers or special plastic tweezers, which are supplied with most units.
If any electrical device does not work, first check the condition of the corresponding fuse. The best way to check a fuse is by testing with a test light. Make sure there is voltage at the protruding terminals (see illustration). If voltage is present at only one terminal, a conclusion should be made that the fuse is unsuitable. A blown fuse can also be detected by visual inspection (see illustration).
3.3a. All presented proposals have a single rated current of 10A, but differ in size: there is a miniature fuse on the left, a medium one in the center, and a large fuse on the right. When purchasing replacement fuses, match them to the items you are replacing in terms of size and amperage
3.3b. When a fuse blows, the conductive element between the contact terminals is destroyed; on the left is a blown fuse, and on the right is a usable fuse
The new fuse must have the same rated current as the blown one. Although fuses of different amperage ratings are physically interchangeable, only fuses of the specified amperage rating should be used when replacing. Replacing a blown fuse with a fuse of a different amperage rating is not recommended.
Each electrical circuit requires protection by a fuse of a certain rated current. The calculated current value is marked on the fuse body.
If a fuse blows immediately after replacement, determine and eliminate the cause of the blown before replacing again. In most cases, the cause is a short circuit in the electrical wiring caused by a broken or exposed wire.
Fuse links
Some circuits are protected by fusible links. Typically, such circuits are usually in an open state, such as the ignition switch circuit.
The fuse link of the generator circuit is located in the wire connecting this element to the battery; it's easy to spot (see illustration)
3.7. The fuse link is the connector of the wire going from the battery to the generator
The insert is a short piece of large-section wire, the sheath of which is marked «fusible link».
Before replacing the fuse link, disconnect the negative cable from the battery.
Warning: On models with an anti-theft system, the system activation device must be turned off before disconnecting the battery cables (see the beginning of this manual).
It seems that the fuse link has a larger cross-section than the wire of the protected circuit. In fact, this is explained by the fact that the insert has thick insulation, but at the same time consists of several wires, the cross-section of which is smaller than the cross-section of the circuit wire. The inserts cannot be restored - if necessary, they are replaced with an element with similar characteristics. The procedure for replacing the fuse link is described below.
- A) Making a cut just behind the connector, cut out the replacement insert from the wire.
- b) Cut approximately 25mm of insulation from the wire.
- With) Connect the bare wires and push them together, then twist the connection (see illustration).
- d) Solder the twist using rosin solder.
- e) Completely insulate exposed wires with duct tape.
- f) Connect the negative battery cable. Make sure the restored circuit is working properly.
3.9. To replace a fuse link, cut out the damaged section, then connect the new fuse link into the circuit by connecting and twisting the wires as shown in this illustration. After connecting the wires, solder the twists and wrap them with insulating tape
