Fuses are small, but very important vehicle details. Their role in the car is very significant. If the fuse does not burn with a short closure, then the car burns down. Independently replacing the fuses are very simple, if you know where they are located. About this further in the article.
Automotive fuse block
The name itself explains why this small element is needed - it protects various vehicle mechanisms from excessive loads, taking a blow to itself, thereby not allowing the failure of electric wiring car.
With a short circuit, harsh and powerful casts occur. In the design of the fuse, the alloy jumper is obligatory, which is burning with a large current than the electrical circuit opens.
Types of fuses
There are three types of automotive fuses:
If yours vehicle Released earlier than 1980 or a little later, you most likely have ceramic fuses. Glass tubes are another obsolete type of fuses, which today is also quite rare. And the third look - flat blocks - most likely, they will stand in your car.
Fuses of modern cars why they are different colors
Fuse manufacturers make them color depending on the nominal, which is quite convenient for car owners. Having a colors table at hand, you will not be mistaken during the installation of the fuse.
Where are the fuses of a modern car
A shield with fuses, as a rule, is located in the cabin of the car under the instrument panel. The fuses are hidden behind the plastic lid, which is most often clearly marked. Open the lid. Here you will see a string of multicolored fuses located chaotically. Most likely, here you can also find a scheme (or on the opposite side of the lid, or somewhere nearby), showing which fuse which device corresponds to.
Why fuses burn
The reasons for which fuses burn out are somewhat:
How to learn a fuse overwhelmed or not
There are two ways using which you can verify the health of the car fuses. The first is based on extracting them and visually inspect that not very reliable.
This situation implies the use of the tester. Checking the fuse with the tester, it must be set to the diagnosis of the integrity of the chain. When the fuse is intact, the tester arrow will rush to zero, which indicates zero resistance.
The second method of determining the burned fuse is based on a more convenient technology and when it does not have to remove the fuse from the socket. To do this, you will need a probe. Turn on the non-working chain, and then in turn, touch the outputs of the fuse using the probe. If there is a voltage in one output, and on the second is missing, then the fuse is faulty.
How to find out the fuse which chain burned
To find out, the fuse which chain burned, the sample method, turn on the turnover of the heating, fan, headlights (near, long-range, fog lights), air conditioning, tape recorder, heated rear glass And other electrical appliances. Bind of one prevent the inoperability of the entire chain entails the inoperability.
Fuse block one or two, if two where is the second
If you did not find the desired fuse under the instrument panel, do not worry. There is also a second fuse block, which is located under the hood. As a rule, it is very easy to find due to the obvious scheme, which is drawn on the lid.
MINI, MAX, MEDIUM fuses than different where apply
To date, different fuses mini, max, medium, which differ in overall dimensions and constructive features: mini - small (come in conventional and low), max - large, medium - medium.
Advice Property: Burned Fuse - Signal Possible Problem
If the fuse burns out, it may indicate problems with a specific instrument or a node, for proper work which he answers. That is, the fuse indicates where a malfunction was "hid" in the electrical system.

The electric part of the car includes fuses that are designed to take care of the electrical circuit in the event of any breakdown. How do they look? The fuse block saw each driver, and most of the car owners periodically faced with the need to replace these elements. But often there are other situations when the fuse is not simply blocked, and such trouble occurs regularly. It is not good. Let's try to deal with the reasons and learn how to fix the situation.
The main reasons for the release of fuses
Among the basic reasons you can select several. Some of them are very serious, others are quite simple and banal. For example, a typical situation when the fuse established in the chain fails overall lights. It is worth only the driver to include these lights, as they immediately go out. And the reason in this case is absolutely simple and ridiculous - overwhelmed happened because it had a smaller power. Let us try to highlight the main reasons why these items fail and spoil the life of car owners.
Bad connection
When the safety element of the electric chain of the car is poorly connected to the block, if the contacts of the element are not fixed sufficiently, then there is a great chance that plastic details The fuse is melted. Such an element will necessarily fail.
In order to solve this problem, experts recommend purchasing a product from another company, which is better known as the component manufacturer for automotive electrician.
But the replacement of the item to the better and expensive does not always allow to solve the problem. Because of oxidized burnt contacts, sparks may occur. This contributes to the outlet of the fuse. And no matter what the quality of the element, which is its power. Sometimes you first first clean the contacts and improve the connection, and then install a new fuse.
Wear
Many people think that fusely safety elements burn out instantly and immediately. This popular confusion is actually all a bit wrong. AT critical situationwhen really in on-board network There is an increased voltage, the part of the brave is immediately. However, when all parameters are within the electrical network within the normal range or exceed the norm only a little, the fuse fuse can be broken down little by little.
The section decreases every time even with minor overloads. At one fine moment, the detail will completely collapse. That is why the fuse blows - not necessarily fully disassemble the whole car. Causes can be quite simple.
Incorrect choice
And this is also a simple reason, but it also leads to unpleasant situations. Often, sellers in stores are not well known to know what they sell. Also, not every car owner knows the laws for which they work electrical circuits. Often there is a situation where the fuse is incorrectly selected by the current on the network. As a result, it cannot withstand the load in the chain in which it was turned on. It is worth a current, and the fuse has blocked.
Voltage jumps
In the on-board network of cars in which safety elements work, voltage jumps may occur.
Due to these jumps, fuses may also fail. This can be observed when the electric motor is blocked, on which the elements of the electrical onboard network depend.
Violation of the scheme
If the fuse has blocked, it is worth looking for errors and disorders in supplying the current to the chain. When electricity goes along a smaller chain than it provided for the manufacturer, then resistance drops. So, through the element will pass larger, not the one for which it is designed. Most of the automotive electrician is not designed for high loads. Therefore, fuses are used there, which in the case of critical situations will save electronic devices.
Short circuits
This is one of the serious reasons. If you can easily touch the opposite polarity, then a short circuit arises. For this reason, the stove fuse often burns out. And it will burn until the owner replaces or does not exceed the damaged wires.
Short circuits can happen in any section of the electric system of the car. Many complain that the fuse fails, which protects the cigarette lighter. First of all, you should not disassemble the connector, remove it and go for the new one. Everything can be much easier.
If the cigarette lighter, then the case can be in high power of the device, which is connected to this cigarette lighter. It can also be as a contact. Often, the Chinese adapters, and the quality of the contacts in them is very low. Recommended before applying radical measures at first carefully examine the design of the cigarette lighter and find weakness. Usually there are such places - short circuit can easily happen in them. You need to thoroughly inspect the contacts and, if possible, somehow exhibit them. Usually, after a weak point is found and the reason for the KZ is solved, then no longer burns out the cigarette lighter fuse.
Diagnostics
The cost of fuses is very affordable. Most people carry them with them - there is a whole set in the trunk. You can easily be installed in the block without difficulty. The situation when the fuse fails - quite normal, because even the most reliable chain Not protected from voltage and current jumps. If these blows happen very often, then careful diagnosis is needed.
If any of the fuses burns immediately, as it was installed in the chain, then the first thing should be found out which device leads to this. To do this, look at the technical documentation for the car to find out there, which devices are in the chain with this fuse. Then include all consumers who are in collaboration with this item.
Next, take a screwdriver with a well-insulated handle and its metal part relate to the terminals in which the element is installed. If there is a spark, then a malfunction in the chain. Disconnect one of the electrical appliances and concern the terminals again. When I won't slip around, it becomes clear why the fuse blocked. The last disabled device is guilty.
on the road?
If the problem happened right in the course of the movement, and there is no spare fuse, then the situation can be solved with the help of remedies. Instead of a safety element, you can use a piece of foil from the pack of cigarettes.
This is a paper-based foil. It is so thin so that in the case of a short circuit, it turns around the same way as the Vase fuse brave. This will allow not only to establish the work of the on-board network, but also protects the chain from overloads. Some use the wire, but it does not give such protection. Coins, stationery clips, as well as other inserts from metal in the case of a critical situation will remain integer. But the device that is protected by the fuse will fail. There is a second option, but it will require the minimum knowledge of the electrician car. So, if an important fuse burned down, you can take a protective element of the cigarette lighter and install instead of the burnt.
How to buy high-quality fuse?
These elements for cars cost much lower than that electrical equipment that they must protect. Therefore, experts do not recommend saving on their acquisition. It is better not to prefer inexpensive dubious models. You need to purchase only those products where all parameters are perfectly observed.
Since there is no possibility to check each of the elements from unknown brands, acquiring such a product is better to pay attention to the products of companies that are released. Among the most famous manufacturers. Reviews celebrate "Bosch", "Hella", "Waib" and "Sound Quest". Buying products from an unknown company, should first check them, and then install it on the car. You can simply check - the new item is connected to the battery. If he burned right away, then the product is high quality. If, with a CZ, the product does not burn, but melts, it is better not to put it on the car - it will not be able to protect the electrical appliances in the case of increased current.
How to replace?
Change the burnt element is quite simple. For this you do not need to have specialized tools and knowledge. First you need to find the location of this item. Where can he stay? And there are fuses in different places. In some cars, they are under the hood, in others - in the area of \u200b\u200bthe front torpedo. They are hidden under the lid. After opening it, you can get a burning element with two fingers and set the new one.
Conclusion
These are all the main reasons. Fuse breaks - it means you need to look for a problem. It can be both simple and banal and difficult, and it will be not easy to find it. Best have new new protective elements. Then you don't have to ick foil, wrappers from candy or paper clips. You can see the fuse and go further.
The role of fuses in the car is very significant. They perform a protective function, protect dear electrical devices from short circuit, from unexpected voltage jumps. Keeping any electrical appliance, the fuse sacrifice itself and stops its functioning, burning. To restore the former work of a certain electrical device in the car, you just need to replace the corresponding fuse. But there are such cases that the fuse braves with too frequent frequency. In this regard, it makes sense to think, and whether everything is in order with automotive electrical wiring? If you are interested in why one or another car fuse burns out, then the answer you will find in this article.
The main reasons for the fuse brave
Among the main reasons why the cigarette lighter fuse is burning or some other consumer of electricity may be present both very serious and quite banal. For example, we will analyze such a situation when the gabaris fuse burns out. It is only worth turning on the car light, as it immediately goes out. And the reason may be completely remapable - the installed fuse has a smaller power than is necessary for correct operation.
Suppose the current current is 15 A, and the fuse is designed for 12 A. Of course, it will melt, since the current is not designed. therefore putting fuses only require the power that meets the requirements. In no case, as you already understood, do not put fuses with less power, and even more so with more.
In addition, if the fuse in your car burns up constantly, then the malfunction can be wounded in the electrical chain itself. Suppose the contacts that the fuse sits down, are in poor condition. Nagar appears on them, or the fuse has poor fixation. As a result of poor contact, sparks arise, which contributes to the fuse brave. And it does not matter how high-quality and powerful fuse you put, it will still be a bit, until you get rid of the problems that have arisen, that is, do not clean the contacts.
The most serious problem is, of course, short circuit. For example, two wires with opposite polarities come into contact, as a result of which such a phenomenon occurs. In this case, do not be surprised if you constantly cut the fuse of the salon heater, because until you make a replacement of wires or do not insulate them, the situation will remain unchanged.
And of course, the fuses can melt due to their low quality. These meet, alas, often. Therefore, it is not worth noticeing and buying too cheap and unknown fuses.
Here we are with you and disassemble the most common problems of fuse bravery. It is worth noting: if the replacement of the burnt fuse on the new and cleaning contacts did not give results, better decision will contact a qualified car service. With electricity jokes are bad, as in such cases your car is exposed to a large risk of fire.
Checking the safety of the fuse
There are two ways using which, you can check the efficiency of automotive fuses. The first is to remove them and visually digitize that it is not quite reliably. In this case, the use of the tester is meant. Checking the tester fuse, it must be set to check the integrity of the chain. If the fuse is whole, the tester arrow will strive for zero, which means zero resistance.
The second way to determine the burned fuse is a more convenient method than in the first case, and when using it, the fuse will not have to extract from its socket. To check them, you will need a probe. Turn on the non-working chain, and after the order, touch the probe to the fuse conclusions. If there is voltage in one output, and on the other it is missing, it means that the fuse is faulty.
Replace the faulty fuse you must be similar, which is designed for the same current value. Do not use "bugs" - they can output the electrical equipment of the car. Even factory fuses can be married and not burned with a short circuit, but simply melted.
To check them, you need to destroy one fuse. Mix it to the conclusions of the wire, and then tap the battery. Qualitative burns immediately, and such a fuse can be safely used in the car.
To protect the new fuses of your car during a short circuit, it is necessary to find out the reason for which it appears. To do this, check the wiring for the presence of damaged isolation. Especially carefully approach the inspection of places where the wires come into contact with the case. During the movement of the car, a re-closure will occur, so you need to understand, detect and timely eliminate its cause.
Replacement of the burnt fuse
The replacement of the fuse in the car is actually a completely difficult procedure, it is simply necessary to clearly stick to a number of rules:
1. Find the right fuse.This is perhaps the most difficult thing if you take into account the lack of information about its location. In addition, several fuses may have to a certain electrical system.
2. Remove it. Sometimes it is quite problematic without special devices, such as forceps. By increasing the number of electronic modules in the car, the number of fuses is constantly growing, and the places in it no longer becomes. Therefore, this problem is solved by a decrease in the size of the fuses themselves. This leads to the fact that they can easily get it, hook and remove them with their fingers becomes almost unrealistic. But, for example, in cars Ford. In the covers for fuse boxes there are special tongs for removing them.
3. Make sure the fuse burned down. You can learn about it, looking at him. Often, today the fuses are made of transparent plastic, through which the thin wire is visible, which in faulty element Melts, and this is well noticeable through plastic.
4. Put the right fuse to the desired location.The main thing is to establish a similar fuse at the same nest, where there was a failed "fellow". Fuses are available in different colors - Blue, red, yellow, on which various numbers are written - 3, 5, 15, 20, 25, 30, and so on. This is the denomination. Never put the fuse of another nominal, it is important! If you removed the blue fuse by 30 amps, then do not put on 40 or 20 amps. It may pour out in expensive repairs. Put just the same as it was. Delivered blue for 30, it means to insert a new blue for 30! There is nothing difficult in this!
The second important task is to place the revealed fuse at the same place where you were taken out the former burnt. It will sound, perhaps and ridiculous, but in the dark, or with poor eyesight, people sometimes fall into those nests, and the results of this sometimes are strange, but often crying. The fact is that in modern carsmobile fuses stand in boxes together with electronic modules. Putting the fuse to another location, you can get the module to work differently, and the car can start strangely behave, for example, you will not be able to turn off the engine with the headlight light on, or when the ignition is turned on, the headlights, windows or something else will work for a couple of minutes. .
That's all. Pretty simple rulesthat can be adopted and which can save you time and money. It is best to have complete fuses from those that apply in your car, flashlight to replace the fuse in the dark, hips, if you can not remove the fuse with your fingers and, perhaps, the magnifying glass, if you have bad eyesight and You cannot see the number of the fuse and the nominal on it.
When the fuse cuts into the car, none of the car owners, as a rule, does not "bother" on this occasion, well, so what? We will put a new one ... In principle, it is so, the fuse is already its name says that it protects something from something. Burning, the fuse saves expensive automotive equipment from the failure and damage.
But if you look at the root of the problem and "shill" deeper, then the question is why the fuse is burning will be much more serious than it seems.
Why burns fuse? This is derived from the overload of the voltage in the aircraft of the car, due to the short circuit of wires, some device, moisture and other sources that can cause overload.
The fuse has a belt in the contact places with the terminals with which it contacts, sometimes it will slip current, or it may not be in general, because in such cases a contact is very bad, or it is not at all. In such cases, a completely "whole", at first glance, a fuse with a whole strip, it will not work, because the current will not go through the belt.
Actual:
If after replacing the fuse you immediately get a blown fuse again, do the following. Alternately disconnect all consumers for which this fuse is responsible. Then, to check, touch the screwdriver to the tips of the fuse fastening terminals, seeing sparking. Continue shutdown, after each new shutdown, check the sparking. Disconnecting the consumer who has problems, you will return to the operating status of the chain protection, after that the fuse will no longer be abrupt. Provided that you will repair a faulty device that caused a closure and burnout.
Many establish the so-called "bugs", a wire that does not burn out or install instead of a coin fuse. This solves the breakdown problem of the fuse, but does not solve the problem of damage protection expensive device and the chain itself from high voltage. In addition to TOG, it is fraught with fire and melting of wiring and isolation, as a result, instead of a distinguished fuse, you will get huge problems and, most likely, non-working car.
It happens that during detail trip A fuse is burning, and at hand there is no spare and buy nowhere. In this case, you will be helped with a cigarette foil or foil from under chocolate, or take advantage of a thin wire. This will allow you to reach the nearest auto shop or bus station, at the first opportunity, replace the "self-made bug" with a qualitative fuse of the required nominal and continue your movement.
It is difficult to underestimate the role of fuses in the car, which can protect the electrical circuit of the machine from failure in the event of a malfunction. The fuse block saw each driver, many have come across the need to replace these elements of the electrical circuit. But the situation in which the fuses regularly burn out cannot be considered normal, and it should be sorted out what causes them to fail.
Causes of car fuses brave
Everyone automotive fuseLocated in the block and outside it, is responsible for the stability of a specific electrical circuit. If he overwhelms, it means that a malfunction has occurred, which may be isolated or grow into a trend. Several main reasons can be distinguished, which lead to the failure of the fuses:
If one or more electrical devices stopped working in the car, first of all it follows. Their failure leads to the rupture of the chain, which is why the equipment ceases to flow, and it does not function.
Since the price of fuses is more than affordable, many motorists carry a whole set of similar elements that can be installed in an electrical circuit if necessary. The fuse brave is a normal situation, since no electrical chain is not protected from current and voltage jumps. However, when the fuse braves regularly, it should not only be thought about the diagnosis of the electrical components of the car, but also to spend it as quickly as possible.
If the fuse burns almost immediately after it is installed in the chain, it is necessary to determine which device leads to such problems. For this:
After the faulty component of the electrical circuit is detected, it is necessary to repair it or replace it.
Automotive fuses have price hundreds of times lower than the cost of the equipment they protect. That is why it is not recommended to save when buying fuses, giving preference to dubious models. It is necessary to buy only such chain protection elements whose parameters are perfectly observed.
Since there is no possibility to check each particular fuse from an unknown manufacturer, when buying such elements of the electrical circuit, you should pay attention to the brands that are released. Among the most famous companiesThat produce high-quality fuses, you can highlight Bosch, Hella, Vibe, Hollywood, Carpoint and SoundQuest.
By purchasing a lot of fuses from an unknown manufacturer, do not be lazy to check them before installing them. To do this, connect the new fuse to the battery, and pay attention to its behavior. If he instantly blocked, then the fuse is high-quality, and he will be able to break the chain if the current will be transmitted exceeding its parameters. In the event that when the fuse does not burn off with a short closure on the battery, it starts to melt, it should be feared to install it in the car - it will not be able to instantly break the chain, and a destructive increase in the electrical appliances will begin.
