Fuses - location and purpose of Lada Largus fuses

February 27, 2015 Lada.Online 312 280 23

The relay and fuse box is also called the mounting block or black box. If problems are identified in the car related to electrical equipment, first check the fuses and relays. If they burn out, we replace them with the same ones, but first we must determine the cause of the burnout. The article contains a complete description of all Lada Largus mounting blocks.

Fuses and their tasks

Protection of circuits through elements allows timely prevention of failure of expensive electrical components and equipment.
Probably, no one likes to stop in the middle of the highway with a faulty pantograph that does not allow further movement. Here the role of fusible links can hardly be overestimated. Fuses are small plates with two contacts connected by a fusible working element. The main purpose of this product is to protect circuits from the risk of short circuits that damage the electrical equipment of the network. Also, a non-working element may not prevent a fire. The closure process itself initiates the burnout of the fuse element inside the element housing, as a result of which the equipment is de-energized. In this case, it is necessary to find the causes of the problems, eliminate them and replace the fuse-link that has become unusable. The cost of these products is insignificant, so we recommend that you always keep a whole set of fuses on hand. It has different inserts configured for different network loads.

For each pantograph separately, the manufacturer used an individual fuse with its own power settings. When replacing a failed insert, it is necessary to replace it with an analogue one with an identical load rating. Confusion here is unacceptable, since each element is designed for a certain current strength.

The inserts vary in color. The maximum current that the fuse can withstand is indicated on their body. If a failure of electrical equipment is noticed, the first thing you should do is check the condition of the fuses and relays. These components guard the normal operation of the entire vehicle network.

In Lada Largus, these elements are located in special mounting blocks, of which there are two. The first is located in the engine compartment close to the switching module. There are fuses responsible for the operation of important systems, namely:

• motor electrical equipment;
• ignition;
• electrical components of the cooling circuit;
• on-board controller, etc.

The second fuse box can be found inside the LADA Largus interior. The manufacturer placed it on the left side of the panel.

Replacing the fuel pump Lada Largus

For those who have already changed the fuel filter on a Lada Largus themselves, replacing the fuel pump will not be difficult. Let's figure out step by step how this is done.

Please note that the fuel pump on the Lada Largus van changes slightly differently and we will discuss this at the very end of this article.

1. First of all, fold down the lower part of the rear seat to gain access to the fuel pump hatch.

2. Lift the plastic cover and move the carpet to the side.

3. Carefully remove the round fuel pump cover.

4. Disconnect the fuel pump power supply and start the engine. This is necessary to relieve pressure in the system. After running for 1-2 minutes, the engine will stall without fuel, and the fuel will be discharged on its own.

5. Now we squeeze the clamps and disconnect the fuel line from the top cover of the fuel module.

6. Unscrew the clamping ring, resting against the protrusions of the edge of the neck with a flat screwdriver. When the nut is loose, unscrew it completely by hand.

7. We take out the fuel module and at the same time carefully remove the fuel level indicator float so as not to bend it.

8. Disconnect the contact chip from the fuel pump.

9. Remove the lower part of the fuel module by prying the clamps with a screwdriver and disengaging them.

10. Remove the coarse filter from the fuel pump.

11. Disengage the latch from the guide and remove the fuel filter.

12. Heat it with a hairdryer and remove the tube from the fuel pump.

13. Install the new fuel pump in place. We put the tube in and heat it with a hairdryer so that the tube shrinks. If necessary, install a new tube.

We put everything back together in reverse order.

Replacing fuses on Lada Largus

Preparatory stage:

• A set of new fuses;
• Rags;
• Additional lighting if there is not enough natural light;
• New relays to replace.

Algorithm of actions:

• We place the car on a flat platform, open the driver's door;
• From the end of the torpedo we snap off the plastic cover, under which there is a mounting block with fuses;
• Using plastic tweezers, remove each module one by one and check its serviceability. This is rational if we do not know the exact number of the faulty module.

In order to simplify the process of identifying and searching for modules on the board, there are markings and pinouts on the back of the cover. Insert a new one in place of the faulty fuse and snap the cover on.

Replacing modules in an additional unit is no more difficult than replacing the interior.

• Open the hood, in the upper left part of the engine compartment, behind the battery there is a mounting block;
• We unclip the plastic cover of the power supply unit and use pliers to remove the faulty fuse;
• If you need to replace the relay switch, then additionally disconnect the terminals from the limit switches.

Upon completion, install the housing cover of the mounting block in its original place. We start the engine and check the operation of the units.

The average service life of domestic fuses is 50 – 55 thousand km. Foreign analogues “nurse” for 5 – 10 thousand km. longer. If you encounter difficulties with installing the mounting block or replacing fuses, contact a specialist auto repair shop. The functionality of a number of mechanisms and units on a car depends on the quality of work.

Cigarette lighter fuse Lada Largus - where is it located on the diagram?

The Lada Largus cigarette lighter fuse is the most frequently burned fuse, which can cause a lot of inconvenience. In this material we will look at what fuse is on the Lada Largus cigarette lighter and where it is located.

Where is the cigarette lighter fuse on Lada Largus?

The Lada Largus cigarette lighter fuse is located in the mounting block in the car interior. The layout of the Lada Largus mounting block is shown in the photo:

In order to find a blown fuse, you need to open the driver's door and remove the cover of the mounting block. Next, using special tweezers, you can remove the burnt fuse and replace it with a new one.

In order to understand where the Lada Largus fuse is located, let's turn to the diagram.

Lada Largus fuse diagram for the cigarette lighter in the passenger compartment

The fuse for the cigarette lighter of the Lada Largus is located under number F38. At the bottom of the mounting block it is located in the third row, second from the bottom. In addition to the cigarette lighter, this fuse is responsible for the car's audio system.

What is the fuse for the cigarette lighter of Lada Largus?

The Lada Lagrus cigarette lighter is equipped with a Standard (Norma, Regular, Standart) fuse with a rating of 15A. Such a fuse can be purchased at any auto parts store, as it is suitable for a large number of cars, incl. for almost all AvtoVAZ cars.

Dimensions

Why does the Lada Largus cigarette lighter fuse light up?

If the car's electrical system is fully operational, then a common cause of the cigarette lighter fuse blowing is excessive load on the power wires.

This is due to the fact that the cigarette lighter connector of the Lada Largus is often used as a socket for connecting various accessories - for example, a compressor for inflating wheels, various chargers for gadgets (phone, recorder, laptop, etc.), voltage inverters, etc.

Often these devices consume a lot of current, and the wiring is of insufficient cross-section, so they overheat and the fuse simply blows.

However, if you do not use such devices, and the fuse continues to burn, then there is a short circuit somewhere. In this case, you need to sort out the wiring and only then replace the fuse with a new one.

Device diagram and tabular data

All the material we have indicated is valid for the modification of Lada Largus 2012-2014.

To provide access to the fusible links under the hood, you will need to press the latches of the mounting block cover and then remove it.

Here we see the block itself with the cover removed.

The purpose and characteristics of each of the fuses are summarized in the following table; this is the fuse diagram.

As already noted, the second fuse box is located on the left side of the panel, or rather behind the compartment cover. To access the inserts, you will need to remove this very cover, as shown in the following figure.

On the back of the cover is a fuse diagram that indicates the location of each fuse. It also contains spare inserts “A” with different current characteristics. To remove elements from the mounting sockets, there is a special tweezers “B”. It allows you to remove fuses with enviable ease when replacing them with new inserts.

The image shows the transcript of the inserts in tabular form.
