Engine compartment

The Land Cruiser 100 fuse diagram located in the engine compartment includes:

• headlight control units (behind the headlights on the right and left, respectively);
• intake heater relay (middle of the engine compartment, closer to the left side);
• glow plugs (for diesel) (extreme right side of the engine compartment, flush with the intake heater relay);
• mounting block (under glow plugs);
• winch electric drive relay (slightly to the left of the mounting block, above the fuse links);
• fuse links (under the winch electric drive relay, to the left of the mounting block);
• headlight washer relay (to the right of the right headlight control unit).

On the Land Cruiser 100 mounting block there are also relays for the fuel pump, side lights, suspension adjustment and others. Their function is to open and close an electrical circuit.

In the engine compartment there is a mounting block with an impressive list of Land Cruiser 100 fuses:

• pump for gasoline or diesel;
• heated seats;
• stoves;
• fuel heater;
• headlight cleaner;
• motor control systems;
• sound signal;
• throttle control;
• alarm;
• direction indicators;
• central lock;
• window lift drive;
• rear window cleaner and defroster;
• fog lights;
• air conditioner;
• high and low beam;
• generator

If any of the car's electrical systems does not work, first check the condition of the fuses. Perhaps there was a short circuit, and now that the natural protection against malfunctions has been destroyed, the car refuses to start the process.

So, if the fuel pump fuse of a Land Cruiser 100 breaks, the engine will not start: the car does not pump fuel into the highway, and without “blood”, which can be considered gasoline, the heart-motor will not beat.

How to check a fuse in a car

Half of car electrical faults are related to fuses. Their number in the car can be more than a hundred.

The driver must know the types of car fuses, their purpose, methods of checking functionality, replacement methods and determining the rating.

Purpose

Automotive fuses (aka fuse links) in electrical circuits are used for:

• protection against overloads of electrical circuits, fire in case of short circuit;
• protection of electronic components of the car in case of malfunction of electrical equipment and wiring;
• monitoring maximum currents in vehicle circuits;
• a kind of diagnostics of faulty electrical equipment of the car.

The last function refers to the fact that if any electronic device in the car malfunctions, the blowing of the fuse serving this unit will indicate problems in the unit.

Types and Types of Automotive Fuses

Automotive fuses are classified according to the material of the fusible insert into:

• lead;
• tin;
• alloy (tin + lead);
• aluminum.

Their important characteristic is the response time. The faster the insert melts, the more reliably the circuit will be protected during a short circuit against overheating of the conductors and possible ignition.

For this purpose, inserts are made of metals and alloys with a lower melting point (transition from solid to liquid state of aggregation). Some types use spring loading to speed up operation (FJ types).

The car uses fuses of various sizes.

The types of fuses that are most widely used in vehicle systems are:

• MAXI FX – power fuses in the engine compartment;
• FTX NORM – fuses in the engine compartment and cabin blocks;
• FNL VINI - in the engine compartment and interior fuse blocks;
• FJ10 - in the underhood power fuse block.

Depending on the fuse rating, usually indicated on its body, additional color marking is used, more precisely, the main color of its body.

Why do fuses melt in a car?

Let's look at why fuses burn in a car - the most common typical reasons.

Cigarette lighter

The cigarette lighter fuse often fails. In most cases, it is not related to smoking. The cigarette lighter often contains power connectors for additional equipment (radar detectors, navigators, other auto gadgets), a compressor, chargers for mobile equipment, splitters and tees of dubious quality.

In some cases, simultaneous connection of several gadgets can lead to exceeding the maximum current in the power circuit of the cigarette lighter connector.

There are car owners who artificially increase the fuse rating in the power circuit of the cigarette lighter connector. Doing this is extremely dangerous! The cross-section of the conductor leading to the connector may not be suitable for the increased current, it may overheat, causing a short circuit and fire.

Such situations often arise when using an advertised additional electric interior heater powered from the cigarette lighter connector.

Washer

The failure of this fuse is associated with possible freezing of water in the tank and washer system pipes at negative and slightly positive temperatures.

The mobility of the electric pump drive is impaired, as a result of which the current increases and the fuse blows.

To prevent such situations, it is necessary to promptly replace the water with non-freezing liquid and clean the entire system of water.

Dvornikov

It fails if the wipers freeze to the glass or the gearbox jams. Therefore, before starting to drive in the morning in the cold season, it is necessary to check the brushes for freezing to the glass.

Heated glass and mirrors

It may burn out due to a short circuit in the electrical wiring. The weakest wiring points are in the corrugated hoses of the front doors, the trunk door, and under the driver's sill trim.

Stoves

A fuse rated at 30 Amps is usually responsible for the stove. If the heater electric motor wears out, especially the bearings and bushings, the current in the electric drive circuit increases significantly. Timely maintenance of the stove fan helps to avoid such situations.

Lighting systems

They often burn out if the power is set, non-standard lamps are installed, especially xenon lamps with an ignition unit, the current consumption of which is much higher. When increasing the rating, you should simultaneously “strengthen” the electrical wiring of the lamps by laying wires of a larger cross-section.

Engine cooling systems

They fail when the radiator fan current consumption increases for the following reasons:

• foreign objects entering the area of ​​rotation of the fan blades;
• wear of fan motors;
• production of engine lubrication.

Engine control unit

Their burnout leads to failure to start the engine. For this reason, the driver must know where the fuses serving the engine control unit are located. Almost half of all malfunctions associated with failure to start engines are determined by their burnout.

Electric power steering

Electric power steering systems are increasingly being used in automobiles. The electric drive of the electric amplifier consumes a large current; under increased loads, the fuses often fail.

Electric parking brakes

Electric parking brakes on some car models (for example, VW PASSAT B6) are a headache for many car owners. The electric parking brakes are located in an “uncomfortable” place near the wheels.

This contributes to mechanical destruction of the housing, moisture and dirt getting inside, as a result, jamming of the engine, and blown fuses along the power circuits.

ABS systems

As a result of pump wear, the current increases and the ABS fuse blows. This leads to the inoperability of the anti-lock brake system, which is especially necessary when the road surface is in poor condition.

Central locking, power windows

The central locking drives and power windows often jam, resulting in blown fuses. Also problematic is the short circuit of the wiring in the corrugated hose of the door wiring.

How to check the fuse for serviceability

The serviceability of the fuse must be checked by removing it from the socket. An initial check can be done at the installation site, but if there is the slightest suspicion of a malfunction, be sure to remove it.

Video - how to check the fuse in a car:

Before checking the fuse with a multimeter, it should be removed from the socket. The test itself is carried out in the position of measuring the resistance at the lowest limit, or the buzzer. The resistance of a working fuse should be zero.

You can also check it visually. The working element is usually visible through a special window, a transparent housing, or protrudes from the housing. Such a test is often deceiving, since there are microcracks in the current-carrying zone that are not visible to the naked eye.

VAZ 217 fuse box: diagram, functions, purpose

Before you start talking about VAZ 2107 electrical circuits and fuses, you need to firmly learn the following rules:

• When carrying out any auto electrical repairs, you need to reset the “minus” from the battery so as not to accidentally close the circuits of the conductive paths on the printed circuit board of the mounting block. For the same reason, it is better not to use a metal screwdriver;
• the scheme does not tolerate primitiveness. You cannot install homemade products instead of fuses, bugs, etc. Such homemade devices may have critical power dissipation with the release of large amounts of heat, since no calculations have been carried out. This may cause a fire;
• If you see that the fuses you install are burning one after another, then find out the reason before an even bigger problem happens, such as a fire in the engine compartment or a generator breakdown, for example. It is possible that you changed the location of the pins, or mixed up the current strength. The schematic diagram will help you figure it out.

Why do you need a mounting block?

All electrical circuits that supply certain consumers on the VAZ 2107, namely: headlights and direction indicators, brake lights, cigarette lighter, electric heater fan, sound signal, radiator cooling fan and many others need protection.

This is done using fuses, which are capable of passing a current of specified values. Upon reaching a certain parameter of its limit, the fuse burns out, but, “sacrificing itself,” saves the entire circuit from breakdown.

The mounting block, or relay and fuse panel, is designed specifically for convenient maintenance of all electrical circuits; it is located on the right (in the direction of travel) under the hood of the car. In addition, individual relays (electromechanical switches) are for the most part also placed in it, with rare exceptions (turning relays, for example). Their location is separate, under the torpedo.

Order and name of relays and fuses in the VAZ 2107 mounting block

On older cars, there was an old-style block, and fuses with a porcelain core and a conductor strip were used; the wider the strip, the greater the current flow. They did not differ in color, and were of a cylindrical type, located in one safety row. The top of the block is covered with a decorative dust and waterproof panel.

• On newer cars, a new type of mounting block is installed, with pin fuses, which are marked by color - red ones are designed for a current of up to 10 A, yellow ones are designed for twice as much, up to 20 A.
• Let us consider in order all the relays and all circuits protected by fuses.
• In the VAZ 2107 mounting block, three cubic elevations are visible. These are relays, or electromechanical switches:

• R1 – rear window heating relay, its fuse F5;
• R2 – high beam, its fuses are F12 for the right and F13 for the left headlights, respectively;
• R3 – low beam headlight relay, fuses F16 and F17, respectively;

If there is no light in two headlights at once (no matter whether low or high) and replacing the fuses did not help, it is better to change the relay. If this does not help, the lamps may need to be changed or there is a problem in the wiring.

There are free “seats” for relays:

• Headlight washer with cleaner – the most “bourgeois” option;
• Sound signal.
• Turning on the “Carlson” - radiator cooling fan.

Special mention should be made about the last two places: jumpers are installed there to “close directly” the circuits without a relay. It must be remembered that if the jumper is not installed tightly and there is an open circuit, then the cooling system fan may fail.

If, after all, the engine overheats, then you urgently need to turn on the heater at full power, with maximum temperature and double airflow, and, if possible, gain a good speed on the highway.

The set includes a standard place for tweezers, which are convenient for changing fuses:

Below is a diagram of the location of the circuits relative to the fuse numbers. They are coded as follows (the second column is the maximum current strength, A). A schematic diagram of electrical equipment can help those with better visual memory understand it.
