Fuse VAZ-2114. Fuse block VAZ-2114: circuit

An integral component of electrical appliances and various radio electronic devices is a fuse. The main functional purpose of this element is to protect the device from various types of malfunctions. They can arise as a result of errors made during installation work, with improper inclusion and emergency situations in the network.

How does the fuse work?

The switching is carried out in series in conjunction with the consumer of the current. In this case, the current circuit breaks if the nominal parameter is exceeded, which is set in the accompanying documentation. The fuse plays a particularly important role in vehicles. This part in case of exceeding the rated current (at least twice) is triggered within 5 seconds. The fuses intended for installation in the car, carry out the work within hundred hours. A characteristic feature of such elements is a reliable enclosure. It does not melt even if the current is 10% higher than the rated current. On the pins, the voltage drop is allowed within 150-115 mV (depending on the type of product). Up to 150 mV is acceptable for fuses 3.5; 15; 7.5; 10 A. To 115 mV 30 A are allowed.

Fuses VAZ-2114 (injector)

The car uses a single-wire system, which is characteristic of a large number of all known machines. The location of the VAZ-2114 fuses is almost the same as in the modern nines. Absolutely for all consumers included in the wired system, there are installed elements that, in the event of an increase in load or in the event of a short circuit, instantly open the circuit. After all, as a result of this malfunction, heating of the wiring and increase of the consumer current are observed. This often leads to a fire in which the car can burn for several minutes. The existing fuses are able to open the circuit of the circuit and prevent heating of the wiring.

Unprotected auto parts

The presence of very high currents, which require individual components of the VAZ-2114, do not protect them with fuses. Such details include the charging circuit of the ignition, starting the engine and battery. The system of these elements uses wiring with a large cross-section and a reliable layer of insulation.

Malfunctions

Very often car owners are faced with malfunctions, which are caused by blown fuses. Identify the fuse, which is out of order, you can independently, without the help of specialists. It should be said that all the elements are in the corresponding block, which can be easily opened and found a malfunction. In this case, it is very important not just to replace the part, but to reveal the true cause of the malfunction. It is necessary in this case to check the connection diagram, whether there is a short circuit there. It should be remembered that frequent fuse blown out indicates serious wiring problems, which can only be remedied with the help of a qualified specialist.

Placing elements

The standard equipment of any car provides for the presence of two fuse blocks. The first, better known as the "black box", is usually under the hood, and the second one is directly in the car interior under the panel. The scheme of fuses VAZ-2114 is described below.

Relay :

• K1 - on the headlight washers;
• K2 - on direction indicators and alarm (emergency);
• К3 - on the cleaner of a windscreen;
• K4 - to check the serviceability of the lamps;
• K5 - on the lifts of the windows;
• K6 - for sound signals;
• K7 - for heating the glass (rear);
• K8 - to the high beam;
• K9 - to the passing beam;
• F1-F20 - fuses are fusible.

Characteristics of the "black box"

The first fuse block is in the hood, that is, the place where moisture can get to. That's why it is made of a plastic box, which is hermetically sealed. In addition to all the standard fuses, the unit houses a relay (for light - near and far, alarms). The power comes from the battery. From one wire with a large cross-section, power is supplied to all consumers. Next, consider the location of fuses VAZ-2114.

Component placement

The first and second VAZ-2114 fuse block, the arrangement of which, in comparison with other cars, does not significantly differ, is reliably protected from damage. Each element, which is located inside the box, is responsible for the operation of one consumer. An example of this can serve as headlight. In his scheme there are four fuses: protection of the passing and driving lights of the left and right side. If, as a result of the operation, an element appears responsible for the driving light at the left, then, in spite of this, the neighbor will successfully operate.

The second "part" of the elements

In its essence, the so-called second block is a set of parts that is placed in the cabin, under the panel. It includes three fuses, three relays and an electronic control unit. What do they correspond to? If viewed from the top down, the first, installed in this section element on the VAZ-2114, - the safety of the gasoline pump. The second one corresponds to the radiator fan relay, and the third one corresponds to the electronic control unit.

Searching for a broken item

Usually in any car there are a lot of fuses. Of these, each is designed to ensure the safe operation of certain light bulbs and appliances. In case of malfunctions, it is easy to check and identify the faulty VAZ-2114 fuse, for this you need to open the latch and lift the lid of the unit. Next, you need to find a sign on the surface that corresponds to the non-working part. For example, the windshield wiper is out of order, so it is necessary to find the corresponding designation in the expanded block. By the way, the VAZ-2114 fuse panel reflects all the elements in the block in the position in which they are shown in the figure in the accompanying documentation.

The main ways to identify a non-working item

Depending on which VAZ-2114 fuse is used, there are two main ways in which it is possible to identify the faulty part. The first is fairly common, since it does not require any special skills. To implement it, you simply need to remove the fuse from the unit and visually check the integrity of the jumper. The second way is more troublesome, however accurate. After all, you can not always see if the whole middle part is in the fuse or not. To determine faults, it is necessary to switch the non-working circuit on and check the elements for voltage. At the same time, they do not need to be removed. If, as a result of the check, it turns out that the voltage is only at one end, then surely the fuse burned out.

Picking up auto with additional equipment

Drivers try not only to maintain the car in good technical condition, but also strive to improve it and make it as comfortable as possible. That's why VAZ-2114 owners very often try to install additional equipment, which is not provided in the standard scheme. For example, often installed alarms, power windows, fog lights. In these cases, without the help of new wiring, fuses and relays can not be avoided. Particular attention should be given to the selection of protective elements corresponding to a particular part. Very often manufacturers of additional equipment do not indicate information about fuses, so in such cases, a component is used for connection, the operating current of which is calculated by this formula:

• I nom = W max / U.

I nom is the required value of the fuse operating current, W max is the maximum possible power of the consumers. To ensure a more correct operation of the fuse, this value is recommended to be increased by 20%, U is the voltage index in the on-board auto network.

Recommendations for selection

The car fuse VAZ-2114 - one of the most effective means of protecting the car from the closure of the wiring. Choose this element should be carefully enough, trying to avoid a poor-quality product, which in the future can cause serious problems and cause financial damage. In most modern auto shops you can choose and buy a VAZ-2114 fuse. When making a purchase, you need to familiarize yourself with the information about the manufacturer, usually it is placed on the package. However, if there is no information, it is recommended to refrain from purchasing. It is advisable to prefer a fuse, which is made of plastic, because this transparent material allows you to visually detect a malfunction if the fusible element comes to a useless state for further use.
