Electrical equipment VAZ 2107 (injector) provides the work of ignition and many consumers, such as headlights, heater, dashboard, etc. Consumer food is carried out from the battery, which must be permanently provided with charging. But what to do, when there is no charging on the VAZ 2107 injector. Consider the main reasons for this phenomenon.

Bad contact on the terminals of the battery

The basic and most common cause is a bad contact of electrical connections. As a rule, it occurs with a weak tightening of the terminals. With a small square of contact, the terminals begin to spoke and oxidize, reducing the number of current passing per unit of time. Ultimately, the current ceases to go. But the problem may not allow the engine at all.

First of all, you need to check the status of the terminals. If they oxidized, they need to be cleared and treated with solidol. The second point is the correct tightening that must be executed before the failure. In addition, you need to check the contact connections with the body and on the generator itself. In most cases, the problem goes.

No battery charging

Battery malfunction on VAZ 2107

The second problem is the battery itself. The fact is that his work is not eternal, and it has a certain shelf life. For properly operation He is able to serve under 10 years. Its service is determined by its ability to charge. To do this, you need to connect it to the rectifier and measure the time for which it is fully charged. Normal battery Charges at least 20 hours, and installed on the car when driving for 60 kilometers of run.

If the charging occurred very quickly or after charging, the voltage does not go above the limit of 12-13 volts, then such ankb is considered to be faulty.

Generator on VAZ-2107

The generator for VAZ 2107 stopped working

Most often, accompanied by the appearance of the indicator on dashboard. It looks like a red battery. No charging can be for several reasons:

1. Malfunction of the generator
2. Broke the belt of the generator
3. Faulty voltage regulator
4. Worn brushes generator

Previously, the operation of the generator was checked by one simple way - Just filmed the terminal during the engine operation. If he continued to work, the operation of the generator was considered normal. If the machine is stalled - there is no charging. Currently, it is impossible to do so, since ECU ( the electronic unit Control) may fail.

To check the generator use a simple method. You need to connect a voltmeter to the battery during the engine operation and measure the voltage with the stove turned on and the nearest headlights. If it is 12 and lower, the charging is insufficient. Ask a partner to add gas if the situation has not changed, the generator is faulty. If the voltage increases, the relay controller is faulty.

In the event of a malfunction of the generator, you can remove the diode bridge and check it. For this, each diode is inspected for external damage, and its contacts are nicknamed. If he is ringing both sides, it is considered faulty. It can be replaced separately or change the whole bridge.

Voltage regulator relay

The voltage regulator relay is a separate unit that used to be installed on the spar. It is responsible for limiting the voltage if it exceeds 14 volts. The fact is that the rotational speed of the generator can be different, but the voltage from 13.5 to 14.5 volts should be maintained. It is for this that he is intended. Now it is installed directly on the brushes. If the relay is faulty, the voltage will be low, but it will begin to rise to the nominal at increasing revolutions. Thus, its malfunction is determined.

Wear a brush of the generator

If charging then appears, it disappears, then the generator brushes are worn. Therefore, they need to be changed along with the relay regulator. The wear of good brushes must be uniform. In the case when one shorter is different, they are considered to be worn out.

This malfunction of the onboard email / network can be caused by different reasons. In principle, its independent elimination is a simple, and even an amateur will quite cope with this work. The main thing is to have a clear idea of \u200b\u200bwhere, what and how to check if the generator does not charge the battery.

Electrical circuits of various cars are different engineering decision, sometimes quite strong. Therefore, further - recommendations of the general nature relating to the main, most typical causes lack of charging on the car battery. But if you understand the principle of finding a fault and know the device, a complete set of your car, then it is not difficult to eliminate it, regardless of the vehicle modification. Moreover, all the problems are almost identical, whatever the generator type is set to power the on-board network.

No Charging Akb Auto - Probable Causes

External faults

Search for a defective area (element) you need to start with the diagnosis of the electrical circuit and checking the state of all it component parts. Practice shows that the generator itself fails not so often, and the lack of charging current is called, as a rule, external factors. In addition, it is much easier to detect similar defects, and a lot of time will not need a lot.

Oxidation of contacts

One of the most common and simplest faults. First of all, you should check the status of the valves of suitable wires and on the battery itself. Even if the owner of the car systematically serves the battery, this does not mean that everything is in order with the contacts. In addition, at the same time it is notended to check their tightening. Often the lack of charging is due to the fact that the terminals of the wires attached to the battery, "walk". As a result - bad contact or rupture chain chain.

Combustion of the protective element

The fuse block is another "weak" place of the car, and this is quite explained. Rarely who looks at him, although there are contact groups there. It happens that the reason is in it. Sometimes it is enough just to turn the fusion insert in the landing socket, and the fault is eliminated. At the same time, check the integrity of the corresponding fuse. If there is no e-circuit at hand, and it is not clear which of the entire row is responsible for charging the battery, then all the protective elements located in this block are subject to check.

Defect of the drive belt

The simplest reason is its insufficient tension. Therefore, when the engine is running, it slips on the pulley and does not rotate the generator rotor. The removal method is clear - make a suspender. Well, if there is a break, then the output is one - the replacement of the belt.

Malfunction in voltage regulator

This device, depending on the year of release (before or after 1996, for most domestic cars), is different internal scheme. Serviceability is checked using a light bulb, the conclusions from which are attached to certain points of the circuit. Describe the whole process (although it is not difficult) does not make sense, since the technique and the result depend on the modification of the generator and the manufacturer.

If there is a suspicion of incorrect operation of the regulator, it is better to contact the service workshop, since independent diagnosis It is often erroneous. Moreover, if there is no defect detection practices in this device.

Malfunctions generator

Custom wear brushes

It is easy to determine visually. Decision unambiguous - replacement. As an option - their pollution. In this case, it is enough to carry out the simplest then, and the generator will again give the battery charge.

Drive bearing breakage

In this case, the generator is subject to dismantling and repair.

Faulty diode bridge

If it is to blame for sure, it will have to change the entire assembly (depending on the type of generator).

Problems with windings

It is quite difficult to determine the true cause. But even a specialist in place can only state the fact of the output of the generator. Regardless of whether it is a short or intersensional closure, a break, the device will have to be removed and donated. Or acquire a new one.

In the presence of a multimeter, those can save time to determine the defect in the charge chain. In this case, the check should be started from the generator itself. What to do?

• Disconnect the terminal bar and check the voltage rating at the device output (the necessary data is reflected in the passport).
• If it is normal, you will have to connect in turn of all consumers. To do this, you will need a scheme. A fairly common cause of low charging current is its increased leakage. Conducting consistent actions and producing measurements, you can find the emergency section of the EL / chain. This is or strongly worn insulated wires, or a faulty device.

• The burning light in the charge chain testifies that it is, but the current is insufficient. If, with an increase in the revolutions, it goes out, first of all you should check the battery terminals and the state of the generator brushes.
• Weak charging is characteristic of those cars whose owners enthusiastically upgrade their iron horse, installing devices and systems that are not covered with the initial complete set and feed on the on-board network. The generator is clearly not designed for this, and its capabilities simultaneously provide EL / Energy and equipment, and the battery is missing. Lovers tuning it is worth considering and not waste time looking for an imaginary malfunction.

The article provides recommendations for finding the simplest defects in the battery charge chain and in the generator itself. But in most cases, they are enough to not only conduct primary diagnostics. side System Auto, but also eliminate minor malfunctions. And, nevertheless, one of the main rules of repair should be observed: do not know - do not climb. If any difficulties occur, it is better to contact a specialist. This primarily concerns the owners of imported cars.

Successes to you in the study of email / scheme of your iron horse and troubleshooting!

First of all, it is necessary to check the integrity of the fuses No. 9 and 10, as well as their reliable fastening in the fuse block.

In addition, with the apparent service life of the fuses (fuses did not overcome) the fuse can be faulty. The fact is that despite the fact that the insert does not overcome, the fuse is nevertheless faulty. From a long service life, the vertices of the fuses at the entrance of them are inlet. This can be determined visually. For this, the fuse is removed from its nests and examines the upper and lower parts of the fuses that are continuing fusing insert. Visually will immediately be seen the wipe edge of the circle of the circle, like a trace from the socket where it is inserted. Such fuses are replaced, and charging is again checked.

If, after replacing the fuses, there are no battery charging on the VAZ 2106, then the troubleshooting should be continued.

Next, you need to check the integrity of the generator drive belt and its tension. If the belt is not torn and its tension corresponds to the norm, then you need to check the condition of the drive pulleys. With the wear of the inner surface of the pulleys, the generator belt begins simply slipping, which will also contribute to the incomplete charge of the battery or the charging will be completely absent. Check it can be visually looking at interior pulley. If it glitters, then the belt slippers and it was he who polished the inside of the pulley.

Such a pulley is subject to replacing the drive belt.

Next reasonwhy there may be no battery charging, it is a bad contact on the battery terminals, or their oxidation. Unreliable contact is tightened, and the oxidized terminals need to be treated with water soda. Soda neutralizes oxided after which the terminal needs to rinse with water and wipe well. To guarantee the residues of the oxide are removed by small skirt. The terminal is then needed to lubricate, such as lithol 24 lubrication. This operation must be done with the terminals themselves. No need to clean the terminals with a skin or scribe them with a knife. They are very pyllava, since leads from lead and three or four such procedures will noticeably reduce their diameter, which will make it impossible to make a high-quality tightening of the terminals, which means there will not be their reliable contact. Trust this question Soda and it will perfectly clean the terminals from the oxide.

It is worth checking out the contact points of the terminals on the generator, which also need to be released from the oxide.

If in the VAZ 2106 car there is no battery charging, then it can be brushes in the generator set. They may have limited wear, or dine in the jacks holder.

To check the brushes, the generator does not need to be removed from the car, as the brush node is available and easily removed. Worn brushes are either replaced or the entire node changes. Moving brushes is tested by pressure. Brushes should easily enter their wells and easy to return. Otherwise, the brushes are removed, and the wells are cleaned, burrs are also removed from the brushes themselves.

The contact of the generator with a mass of the car is also checked and recovered if necessary. Sometimes it is sufficient to release the fastening of the wires with the mass and take the wire from the side to the side, which will be enough to restore reliable contact. For full control, the wire is removed and the tip is being cleaned.

Possible malfunctions of the VAZ generator 2106

In the generator itself, there may be the following faults:

• Damage to the diode bridge (in the people - "Horseshoe")
• Malfunction of stator winding - intersensional closure, closure on the body or internal break
• Malfunction of the rotor excitation winding, with symptoms similar, as in the stator winding. In addition, there may be great wear of contact rings, which violates their reliable contact with brushes

If, when checking at the output of the generator, there is a normal voltage of 13.5-14.2V, and the battery does not charge, then it is necessary to check the integrity of the wire that goes from the generator to the battery.

The lack of charge can affect the relay - regulator fault, as well as its bad contact with the "mass".

If you suddenly noticed that in your car, the VAZ 2107 disappeared the battery charging, this malfunction should be eliminated immediately. If you operate a car without charging, the battery will very quickly sit down and you will have to use the tow truck or towing.

To find the cause of the lack of battery charging and how to eliminate this problem must begin with the theory.

Causes of battery charging

For the proper operation of the ignition system and other electrical schemes of VAZ 2107 voltage in the onboard network should be permanent. With non-operating engines, the constant voltage supports the battery. After starting the engine, the car generator comes into operation, it provides charging the battery and supports the on-board network voltages in the range of 13.6-14.2 volts. Regardless of the revolutions, the voltage on the generator must remain constant. This is provided by a regulator relay, which, depending on the revolutions, changes the voltage of the generator chain. If the voltage drops below the permissible level, the winding current rises, increasing the output voltage and vice versa.

If there is no charging on the VAZ 2107, possible reasons May be as follows:

• bad contact or opening in the excitation network of the generator output voltage;
• faulty relay regulator;
• open the generator belt.

Troubleshooting the operation of the generator should, first of all, begin to identify the cause of the absence of the battery.

How to find the cause of the absence of battery charging

The first feature of the lack of charging is to light the control lamp on the instrument panel or if the voltmeter arrow is not in the green zone when the engine is running. You can more accurately check the battery voltage using a multimeter.

With the engine running, the voltage on the battery must be - 13.9 ± 0.3 V. If the battery is not charged, the voltage will be approximately 12 V.

Warning: To avoid the failure of the ECU and the regulator relay, it is prohibited when the engine runs running the battery terminals.

Increased or low voltage on-board network harms a battery. In the first case, the electrolyte is thrown out, in the second - it is discharged, which leads to the failure of the battery.

To find a malfunction and eliminate it, you will need the following tools and appliances:

• control lamp 12 V;
• multimeter;
• flat screwdriver;
• passatia;
• sandpaper.

Elimination of battery charging

First of all, it is worth checking the tension of the generator belt - it is it that drives the generator and the cooling fluid pump, so this malfunction may also appear to the engine overheating.

If the VAZ 2107 battery charge lamp is not lit, and the voltmeter shows the normal voltage of the on-board network and at the same time the battery does not charge, the reason in contacts on the terminals are obvious.

You need to remove the kelves from the battery and clean them with sandpaper. If charging does not appear, it is necessary to measure the voltage at the output "30" of the generator with the engine running. If the readings voltage at this output and the battery have a strong difference, you must clean the contacts and check the wire that runs from the generator to the battery. If the wire is faulty, it is subject to replacement.

If the voltage is in the onboard network within the engine running, but when the headlight is turned on, it drops, the reason in the weak stretch of the generator belt. With an increased load, the weak belt is running. Right stretch Belts, this is when with an effort of 10 kgf, it should be fed by 12-17 mm.

Another reason for the lack of charging can be a closure or breaking of the stator or rotor winding, as well as a punched diode of the rectifier on the generator.

Diodes can be checked using a control lamp or a multimeter to check their resistance. To check the diodes with a control lamp, you must remove the "+" terminal from the battery and connect the control lamp to one end to the plus terminal, and the other you need to consistently touch the three bolts shown in the figure below. Then to do the same operation, only with the terminal "-". If the control lamp lights up, then the diode checked is broken.

At the failure of one of the diodes, it is necessary to replace the diode bridge assembly.

The stator winding fault can be determined by a multimeter, measuring the resistance between the rectifying unit mounting bolts. If there is no contact between them, then there is a disconnection of the winding. In this case, the winding or generator is changing.

Probably the most common cause of the generator breakdown is to wear brushes. To check them, you need to remove the brush knot. The length of the brushes should be more than 5 mm, otherwise they need to be replaced. Also brushes can jam or twist in wells.

Note: The injector generator is no different from the carburetor version of the VAZ 2107. All the manufacturers for repair and checking the generator are relevant for both vehicles modifications.

The battery is the only voltage source during engine start. As you can guess, with its inoperability, the motor will be problematic. In this article we will tell why automotive generator Does not charge on the battery and what to do in such cases.

No charging process

That the generator does not charge on rechargeable batteryCan report a diode indicator located on the control panel of instruments. As a rule, this icon is depicted in the form of the battery itself, and when the electric part on the engine operating normally works, it usually does not shine. You can see this indicator on the shield after you turn the key in the lock to position I. At this point, all devices are diagnosed, so the appearance of the indicator at this point is quite normal. In the event that the indicator continues to burn while driving on a car, this may indicate that the generator does not charge the battery.

Accordingly, such a problem is necessary to solve as quickly as possible, since otherwise it may lead to more serious consequences than simply the indicator appeared on the tidy. Sometimes the generator node does not charge the battery due to the inoperability of the latter. And to solve somehow such a malfunction except by means of replacing the battery will not work. But sometimes it may be due to incorrect work and generator.

Causes and Methods for troubleshooting

If you have the opportunity to take someone else's battery to check, you can try it to put it instead of your car. Of course, this acb must be fully working. Actually, so you can find out what causes the cause of the problem - in the battery or in the generator. Below will look at the reasons for such a malfunction.

Internal state of AKB

Usually the reason why the generator cannot give a battery charge, lies in the sulfation of the latter plates. In this case, the surface of the plates can be covered with salts - partially or completely - which do not allow the battery to recharge. In the event that the degree of coating plates is small, in principle, you can always try to restore the performance of the battery. However, if the process of destruction is already irreversible, it will be necessary to replace the device.

As for the restoration of the battery design from sulfate, this process may not take one day, and the result and recovery quality cannot be guaranteed. This means that in any case you may need a new battery over time. The resuscitation procedure, as a rule, begins when there are no signs of bloating, mechanical damage, cracks, etc. on the battery. That is, the device body must be integer.

But it should be borne in mind that the external state is not always a guarantee that the result will arrange. Inside the design there are banks in which the plates can be crumbled, which ultimately leads to a short circuit. If so, then except for the purchase of a new battery there are no other options.

Terminals

Sometimes the appearance of the light indicator can occur while driving by car. At this moment you should not succumb to panic, because the reason may be pretty banal. At the side of the hammer or in a hole from the battery, it may simply be able to fly a contact, it is especially possible if the terminal was poorly screwed. If so, then it needs to be simply returning to the place and strongerly tighten.

Problems with terminals can manifest itself in case of their oxidation, in the place where they are connected to the output. To solve this problem, the oxidation needs to be simply cleaned. To do this, we need sandpaper shallow grain paper. In the process you need to be as cautious as possible, since it is possible to randomly cut the lead part of the output, and this is unacceptable. If you erase more layer than necessary, the terminal will be bad and starts to subscribe on each batch (the author of the video - Avramenko Garage).

Generator belt

Which charge should give the generator and for what reasons is the reload or the impossibility of charge ankb? Quite often, the problem lies in the node strap - with a weak tension, the belt will start slipping on the shaft, at the moment the node will not be able to feed the voltage. The battery switching and the charged battery turns from the energy consumer to the consumption source, which is gradually discharged.

Diagnosing the degree of tension of the strap can be performed on the power off. If the engine is disabled, it can if necessary, you can try to pull up. But it should be borne in mind that slippage may be due not only to poor tension, but also wear a profile. Such a problem will be solved only by replacing the strap.

The impossibility of transmitting rotation can cause a wet or wet shaft - the strap will slide on the surface without an effort. In order for the battery to be properly charged, the pulley must be dry, so it will only be enough to dry. It is difficult to determine slippage rather difficult, in this case the strap can occur.

The cause of the problem can be in the oxidation of the wires on the generator node in the places of compounds. If you have noticed white flag, as stated above, it can be deleted using sandwich. Spend a visual check on the possible availability of cliffs of wires or burnt contacts. If the wire burned, it may indicate a characteristic smell (by video author - VAZ 2101-2107 Repair and maintenance).

Monitoring other elements of charging system

To determine why the generator gives a reload or does not charge the battery in principle, a multimeter may be required. Using the tester, you can measure the voltage on the battery in two modes. When the engine is disconnected, the charge parameter should be in the range of 12.5-12.7 volts, with a waged motor - 13.5-14 volts. If these indicators are less on the Internal DVS, this may indicate problems in the operation of a diode bridge or a brush node. By the way, brushes can be labeled, so they must be changed periodically.

If the cause of the recharging or lack of charge is a relay, it can be fixed as a result of replacing or diode repairs. If the diodes are fused, it is necessary to choose the device the most close technical characteristics. Otherwise, they can overheat.

Check generator

The reason why the battery is not charging may be the inability of the generator. If the car mileage is large, it can lead to a rotor generation or to wear rotating elements. As a result, this can lead to doss of parts inside the design and the absence of rotation. If the generator swap, it will need to be replaced, the repair in this case will not give. In addition, the reason may be in the cliff of the chain inside the mechanism. You can identify such a malfunction with an electrician.

In general, most of the problems associated with the lack of charge can be solved on their own. To do this, it is enough just to properly monitor the operation of the node and to devote the time for diagnosing the battery and the generator in the event that the appropriate indicator appears on the tidy.
