VAZ 2107 battery charging arrow jumps

VAZ-2110 is a middle-class passenger car produced by a Russian automobile company. The car debuted in 1995 as the successor to the famous Samara, although it was produced until 2015. The car appeared on the domestic market as the VAZ 2110, and only after 2004 was introduced in Russia as the Lada 110.

The Russian sedan Lada Priora (2170) is another hope for success in the domestic market. Even the Russian professional press was not immediately able to accurately determine the differences compared to the previous model. Initially, unofficially, one of the manufacturer’s representatives described the car as “a deep restyling of the 2110, which is very close to the original.” The suspension and braking system were changed, the body received new contours, although the doors remained the same.

Theory “on fingers”: how everything works

On the VAZ 2107, devices can be powered from 2 sources. The first is the battery, the second is the generator. The battery supplies energy when the engine is off. It has a certain charge that is consumed as needed. The generator produces electricity, but only when the rotor rotates. That is, with the engine running.

Battery operation diagram: 1. Battery, 2. Negative diode, 3. Additional diode, 4. Generator, 5. Positive diode, 6. Stator winding, 7. Regulator, 8. Rotating winding, 9. Capacitor, 10. Unit installation, 11. Test lamp, 12. Voltmeter, 13. Power relay, 14. Lock.

One battery charge is used to start the engine. When starting the engine, the battery energy is not consumed - it supplies all devices to the generator. In addition, a charge is supplied to it to restore the energy expended. But if the battery is not charged, its own energy will be enough for a limited number of starts. Then the battery will be completely discharged. And the car owner will decide how to start a VAZ 2107 if the battery is discharged. After all, not everyone has crocodiles in their trunk, and not everyone agrees to share electricity with a battery.

Which car should you prefer?

Lada 110 is a good choice for its time (more than 10 years ago). But, unfortunately, the car has not reached an acceptable level in terms of quality.

Pros:

good aerodynamics;
affordable price.

Minuses:

very mediocre workmanship and assembly quality, especially the body;
quite high noise level;
“slow”, “slow” and uncertain driving;
uncomfortable steering wheel.

The VAZ-2110 has its fans and a lot of reviews on the Internet. The car is far from ideal and has many shortcomings. On the other hand, for such a price it is simply impossible to choose something better.

Lada Priora is a pretty successful change of style, but the model would have been more relevant 5-6 years earlier.

Pros:

more modern appearance;
good body quality;
airbag;
better handling due to body rigidity.

Minuses:

traditionally low quality;
uncomfortable seats for tall drivers and passengers;
minor flaws in ergonomics.

Lada 2170 (Priora) is a step in the right direction, albeit a very small and late one. The improvements are visible only to those who have not tried a good foreign car, and such drivers are becoming fewer and fewer. In other words, the Priora has many advantages over the “top ten”, but only the owners of the “top ten” will be able to fully appreciate them.

Indicator light

As you can see from the diagram, there are a large number of components involved in the charging system and each of them can cause poor or no charging. A warning light is installed on the dashboard to monitor the battery charging process.

If the system is in good condition, the control signal is activated after the factory. But when the engine reaches operating mode, the VAZ 2107 battery charging lamp does not light up. This means that the battery's energy supply is replenished by the generator. At the same time, the needle on the voltmeter moves to the green sector.

Signs of battery failure:

The VAZ 2107 battery charge arrow clicks.
The detector signal does not turn off. In some cases, the VAZ 2107 battery light blinks.
After starting the engine, the voltmeter needle does not go into the green zone.
With the engine running, the battery voltage should be around 13.9.
The permissible deviation in any direction does not exceed 0.3 V. An undercharge of the VAZ 2107 battery within these limits is still not terrible.

A voltage drop of 12 V says: the generator is not charging! The VAZ 2107 battery charging lamp lights up dimly - the battery is discharged.

Most frequently asked questions

Will the battery be recharged if a higher power generator is installed?

No, because regardless of the power of the generator, the voltage at its output is limited by the relay regulator to the maximum permissible for the battery.

Does the diameter of the power wires affect recharge?

The increased diameter of the power wires in itself cannot cause the battery to overcharge. However, replacing damaged or poorly connected wiring may increase the charging voltage if the alternator is faulty.

How to properly connect the second (gel) battery so that there is no overcharging?

To prevent overcharging of the gel battery, it must be connected through an isolation device. To prevent overvoltage, it is advisable to use a limiter terminal or another voltage controller (for example, voltage control relay 362.3787-04).

The generator recharges the battery, is it possible to drive home with the battery removed?

If the relay regulator is broken, you cannot disconnect the battery at all. Reducing the load will raise the already high voltage from the generator, which can cause lamps and on-board electronics to fail. Therefore, when recharging the car instead of the battery, turn off the generator.

Do I need to change the electrolyte after recharging the battery for a long time?

The electrolyte in the battery is changed only after the battery has been refurbished. Replacing the electrolyte that has become cloudy due to crumbling plates by itself does not solve the problem. If the electrolyte is clean, but its level is low, you need to add distilled water.

How long can a battery be charged to increase the density of the electrolyte (evaporate water)?

Time limits are individual and depend on the initial density. The main thing is not to exceed the charge current of 1–2 A and wait until the electrolyte density reaches 1.25–1.28 g/cm³.

Where to start checking

If the VAZ 2107 battery icon does not light up, the voltmeter gives normal readings, but the battery does not charge, which means there is no (or insufficient) contact at the terminals. Their severe oxidation can simply lead to the fact that voltage from the generator will not be supplied to the battery. Therefore, it is necessary to remove the terminals, thoroughly clean them, as well as the battery terminals, then reconnect the battery to the on-board network and check the functionality of the charging system.

If the voltage on the VAZ 2107 battery is still below normal, it is necessary to measure it at the output of the generator with the engine running. Is there a big difference between the pin and battery readings? Try cleaning the contacts and checking the wire connecting the battery to the generator. Out of production - requires replacement.

The next item to check is the alternator drive belt. When loosened, it will slip along the pulley, as a result of which the generator will not be able to generate the required amount of electricity. And although charging will occur (if the circuit is working), this will not be enough. In this case, the engine is running, the voltmeter shows the norm. However, if the system is loaded a little more, for example by turning on the headlights, the voltage will drop sharply. So, if the battery charge on a VAZ 2107 disappears, this indicates that the tension belt is loose and is slipping. The belt must be tensioned; if it wears out during operation, replace it. But you can’t overtighten either: excessive belt tension causes overload of the pumps and generator bearings.

The third circuit component that is checked during initial diagnosis is fuse no. 10 (in the fuse box). It is he who is responsible for supplying voltage to the battery: the VAZ 2107 battery charging fuse has blown - the system will not work.

If everything is in order with the terminals, the belt, and the fuse, then you need to further look for the reasons for the low charge of the VAZ 2107 battery.

Technical features of the models

VAZ 2110 has a 4-door body. Its “sisters” are presented under the brands 111 (station wagon, until 2004 in Russia – VAZ 2111) and 112 (hatchback, until 2004 in Russia – VAZ 2112). The body design is quite rough and boring. The car looks heavier than it actually is. However, despite its small size, the interior is relatively spacious. The quality of the materials used and their fit leave much to be desired, but the price for which you can buy a VAZ 2110 compensates for any inconvenience.

Lada Priora has excellent sound insulation. If we compare acoustic comfort with a VAZ 2110, then in the Priora gearbox the noise is almost inaudible, and everything else has also become noticeably quieter. The difference in engines is even more noticeable. The 10's engine was far from ideal, so its volume was increased to meet stricter emissions standards (at that time Russia introduced an "obligation" to comply with at least the outdated Euro-2 standard).

The engine has not been modernized in the most successful way, so 16 valves are effective only at medium speeds and downright slow in other situations. The difference between the 8- and 16-valve “tens” engines is insignificant.

For comparison, Priora has a more advanced VAZ-21126 engine, which not only rotates faster and is quieter, but is also much more dynamic at high speeds, which was lacking in older analogue engines. Separately, it is necessary to highlight the energy intensity of the suspension - on a bad road you can drive at a higher speed without much damage to the car. It is very difficult to break the suspension of a Priora.

What else to check

Voltage regulator;
Generator rectifier;
Diodes;
Winding break generator;
Generator brush group;
Contacts on the generator terminals, mounting block.

A malfunction of one of these elements results in the charging system not working and the VAZ 2107 battery not charging.

Continues... Diodes are checked with a test lamp or multimeter. If any of them break, the entire rectifier will need to be replaced.

To check the stator winding you will need the same device. The resistance between the fastenings of the rectifying unit is measured. If there are no contacts between them, it is necessary to replace the winding or the entire generator.

The generator itself often fails due to wear on the brushes. To check them, you need to remove the brush assembly and measure the length of the elements. If it is 5 mm or less, the brushes must be replaced.

Almost all of the above system components are replaced in case of failure, since they cannot be repaired. Only some problems with the generator can be repaired, but only by a qualified auto electrician.

What's even worse is if you have charging problems along the way. Since the battery is not being charged, it will eventually drain completely. And even if the cause of the malfunction can be found and eliminated, it will no longer be possible to start the engine with the starter. It will be possible to start a VAZ-2017 with a discharged battery only from a tug or pusher.

Engines and transmissions

In 2001, a new facelift model of the VAZ 2110 was introduced. The car had slightly more rounded edges and a modernized front bumper. Until 2004, the offer included 1.5-liter gasoline engines with a power of 77 or 92 hp. With. Since 2004, larger 1.6-liter 80- and 89-horsepower engines have been installed under the hood. Power was transmitted to the front wheels through a 5-speed manual transmission 2110.

A year after its debut, the sports version 21106 GTI appeared. The transmission here is based on a 2-liter 150-horsepower engine from Opel, which allowed acceleration to just over 200 km/h. Car enthusiasts are also familiar with the Lada 110 Premier, the difference of which was that the body was increased by 19 cm. It can often be found in the form of a taxi. Under the hood is a 1.8-liter gasoline engine producing 98 hp. With. In 2009, production of the Lada 110 was completed, and the Priora became the model's successor. The VAZ 2110 was offered in sedan (2110), station wagon (2111), five-door hatchback (2112) and coupe (21123) body styles.

The main “disease” of all VAZ 2110 engines is the cooling system. Oxides and deposits often collect here and become clogged in the engine casing and radiator. Due to a malfunction of the sensor, the electric fan periodically fails. The tens clutch also usually fails quickly during aggressive driving.

Every owner of a Ten is faced with the need to replace a piston - the one on the Priora is perfect here. It will significantly improve the technical characteristics, but such an exchange is best carried out after 120,000 km.

The suspension of the Lada-110 is identical to the “nine”. User reviews say that the front shock absorbers are enough for about 60,000 km. A popular problem is the bearing on which the front struts are mounted. The brake system on the VAZ-2110 is also no different from the one installed on the “nine”. Disc brakes at the front, drum brakes at the rear. The former last about 40,000 km, the latter – up to 120,000 km. But the most unpleasant thing about the brakes is the handbrake, the problems of which are associated with the low quality of the parts.

Salon VAZ-2110

If we compare the VAZ 2110 and Priora, Russian manufacturers have been upgrading the latter’s 1596 cc engine for many years. The four-cylinder sixteen-valve engine produces 72 kW/98 hp. With. at 5600 rpm and a maximum torque of 145 Nm at 4000 rpm, which, according to available data, allows the Priora to reach a top speed of 183 km/h, and provides acceleration to 100 km/h in 11.5 s.

What to consider when choosing a new battery

According to the passport, the battery is designed for 3-5 years of active use (in reality it turns out to be less). Therefore, over time, it becomes necessary to purchase and connect a VAZ 2107 battery to replace the faulty one.

When purchasing a new battery, there are a number of parameters and characteristics to consider. Battery type: repairable and maintenance-free. The first option allows you to check and restore the electrolyte level. This allows you to use the battery longer.

The next question is what power the most efficient VAZ 2107 battery will have. This model is suitable for batteries with a capacity of 50-60 A * h. However, since modern cars are equipped with energy-intensive equipment, it is best to opt for more capacious batteries. In addition, carburetor models from VAZ require more powerful batteries - they consume more power when starting. In terms of dimensions, the VAZ 2107 requires power supplies measuring 242 * 175 * 190 mm. The vast majority of samples available on the market are suitable for them.

When choosing a battery, you should also take into account the place of residence of the owner of the “seven”. For those who live in the south, you can purchase a less powerful battery. Nordics advise giving preference to a battery with a larger capacity: in cold weather, the car starts up with greater energy consumption.

Controllability and safety

The VAZ-2110 from the interior was clearly different from cars with modified suspension and struts - the modified camber works wonders. The accuracy and strength of the steering could only be improved after accurate diagnosis and correction at the service station. The newly purchased VAZ-2110 reacted extremely slowly and simply had a large gap in the steering wheel.

VAZ-2110

In the Priora, the torsion bar body is 40% stiffer, which you can immediately feel - the car behaves completely differently. The electric power steering is connected to the same mechanism, so the car still has a little slow response. The steering is quite confident and tight, which allows you to better predict cornering behavior.

The power steering is quite adequate, providing the desired response at medium speeds. In tight S-shaped turns the steering wheel has to turn more than we would like, but the Priora follows the driver's commands more accurately than its predecessor. It is quite possible that with the regular 185 tires that have been announced for the Priora, everything will be better, but for now the car is equipped with only 175/65 R14.

Confronting attackers

Due to the fact that the battery is not cheap, the problem of protecting the VAZ 2107 battery from theft is quite acute. Opening the hood of a “classic” is not difficult, so thieves keep a close eye on the “seven”.

Experts offer several options for preventing theft.

Secure parking or secure garage.
Alarm installation.
Installing a hood lock. Let’s be clear right away: few people take this step. Welding work is required, the appearance deteriorates and it is quite easy for a professional to pick the lock.
Take the battery with you. The timing is inconvenient but effective. If you leave the car for a short time, it is defenseless: the battery can be removed in the parking lot near the supermarket.
Reliable battery mount. Almost the most popular method. Fasteners are installed with a secret that prevents disassembly and makes theft difficult. Combined with reporting, this is a very effective method.

But all experts agree that the most reliable protection for the battery against theft of a VAZ 2107 is complete. A combination of multidirectional measures will give the best results!

Appearance

A significant problem with the VAZ 2110 is floating gaps. This is especially noticeable when the hood comes into contact with the doors and fenders. Sometimes even several fingers can fit into the gap. This is a disease of all VAZs from the “ten” family. AVTOVAZ tried to modify the design - in the mid-2000s, the car only received a new bumper.

VAZ Priora

The wear resistance of the body of the Lada 110 is quite poor. The coating is impervious to salt, water and road chemicals. Rust appears after two years of use. Door sills and bottoms also quickly corrode and rot.

The most important shortcomings in domestic cars of previous generations remain the gaps between body parts. The external body parts of the Priora were redesigned, which resolved most of these problems. The differences are especially noticeable by the lack of contact between the C-pillar and the fender, which was previously covered by a curved plate. It was also possible to almost halve the distance from the new trunk lid to the car body.

What to do if there is no charge, weak charge (battery is discharged)?

If the battery of your VAZ 2107 is discharged, the “culprit” may be one of three elements: the generator, the voltage regulator, the connections between them. Determining “who is to blame” can be very simple, even without additional devices. How - this article will help.

We carry out testing using standard equipment

There are two instruments for monitoring the operation of the generator on the “seven”: a voltmeter and a warning lamp on the instrument panel. With their help, you can track down the cause of your problems.

1) Turn on the ignition without turning on the starter and look at the warning lamp. It should shine in all its glory, as in the photo. The voltmeter needle is usually located on the white section of the scale (photo). Let's say everything is OK - move on to step 2

Battery charge indicator is on

Position of the voltmeter needle before starting the engine (ignition on)

The lamp does not light, the voltmeter needle remains at zero when the ignition is turned on.

Check fuse No. 10 in the mounting block. 99% will be burned. In this case, all other warning lights on the instrument panel will also be de-energized. Replace it with an identical one and double check. If the fuse blows again, you need to look for the cause, that is, a short circuit. We check whether the generator wires are disconnected, whether the insulation is frayed somewhere, etc.

The lamp does not light up, the voltmeter needle shows normal

We check the wires on the generator to see if the wire has come out of terminal “61”. If everything is normal there, you need to check the presence of a “plus” on this wire using a test lamp, an indicator screwdriver or a multimeter.

Terminal “61” of the VAZ-2107 generator

If there is a "plus", look at the "pill" (also known as "chocolate") and the generator.

There is no “plus”: you will have to remove the dashboard and check the lamp. Replace the burnt one. How to remove the panel, watch the video

2) Start the engine. The control light should go out, the voltmeter needle enters the green sector and is located from the center to the right edge (photo). If yes, then most likely the generator is working normally.

The voltmeter shows the voltage is normal (there is a charge)

The lamp remains on or dims slightly

If you release the gas, it cuts out at high rpm and ignites again when they drop. The voltmeter needle is in the white sector and moves towards the green border as the speed increases. Conclusion: the generator is faulty. The same conclusion occurs if the lamp continues to light at any speed and the voltmeter needle is in the white sector and even turns red.

Voltage too low (motor running). Weak charge

3) If the generator is running but the battery is gradually draining, we will do another check. We start the engine, turn on the heater fan and low beam, turn the key to “10” and, loosening the negative terminal of the battery, remove it. The engine should not stall at idle (approximately 900 rpm). If the engine stops, replace the terminal and start again. Maintaining a speed of 1200-1500, remove the terminal again. Has the engine stopped again? Then turn off the headlights, leave the heater fan on, and repeat the test. The engine now continues to run with the negative pole disconnected from the battery. The generator output works, but does not provide the required current, it needs to be repaired.

Note! With such control, it is better and safer to work together. Do not disconnect the battery terminal without at least turning on the heater fan or other load. A power surge during shutdown can “burn out” the electronic components of ignition systems. Be especially careful when using a vehicle with a fuel-injected engine.

Front seats Priora from 2110 or not

July 14, 2011, 09:43 #26

PEOPLE, tell me who installed the Prior seats on the 10 ku, and are they even suitable? Moreover, the question is whether the door trims from the Priora will fit on a 10 cu with a 10 tier panel?

July 14, 2011, 09:57 #27

the seats are the same, at least for now, I won’t say anything about the cards, but I think they’ll fit

PEOPLE, tell me who installed the Prior seats on the 10 ku, and are they even suitable? Moreover, the question is whether the door trims from the Priora will fit on a 10 cu with a 10 tier panel?

As I understand it, you want a Prioro salon, my neighbor does the same with the Priora panel, but there’s still a gap somewhere that doesn’t fit as far as the seats are concerned. They are needed now, whatever buckets you want, they sell them at 10 ku, there are even craftsmen who trim them and make pilot seats out of them.

What to do if the battery is boiling

The lamp goes out, the voltmeter needle goes to the right into the red sector, and there is a strong “chemical” smell in the cabin. At idle, the needle is in the green sector, but you need to “accelerate” - it goes to the right all the way. This indicates that the voltage regulator (chocolate) has failed. If this happens, it will be more expensive to move on! All the electrical equipment of the car could burn out and the battery would be removed, the electrolyte would “boil”, the plates could be deformed. To get to the repair site, you can temporarily turn off the generator by disconnecting the wire from terminal “61” of the generator. With a good battery, you can drive the car for quite a long time, but do not forget to turn off unnecessary devices: heater fan, heated rear window, radio, etc. Headlights or running lights will need to be left on.

Voltage too high (overload)

This article provides an easy way to identify problems with your alternator, voltage regulator, and connections between them. How to fix everything is in the next article.

I have a VAZ 2107 injector, the voltmeter needle points to red from the left, and charging is normal both at idle and under load

Sergey! I saw this, all the comparators were “lying” there. Replacement of the instrument panel assembly. The reason for the interest was found: broken diodes.

VAZ 2107 injector, the generator gave 12.5 V, the lamp is on when the ignition is on, the voltmeter is in the white zone, when the lamp is on the lamp goes out, the voltmeter remains white, I changed the tablet and the diode bridge, it gave 13.2 V, a day later it was 12.5 again

Unfortunately, the quality of spare parts today is simply terrible. Most likely, the diode bridge has failed again. Sometimes, according to friends from the car service center, they place several pieces until they “get used to it.” Or you can try to buy a used generator from autoparsing.

VAZ 2107. The arrow on the charge sensor jumps. Sometimes gets stuck in the red zone. Then it suddenly broke, otherwise at first. The brushes seem normal, I looked. Relay? The VAZ 2107 battery charge arrow clicks.

7 comments on “The VAZ 2107 battery charge arrow twitches. The arrow on the charging sensor jumps”

disassemble the panel and see if the traces on the board are swollen, if so, then buy a new one, maybe the ammeter itself is dead, if the board and the ammeter are normal, the relay itself recently changed the ammeter, it was crap

Sanya, they don’t have an amplifier, but a simple voltmeter

I changed the diode bridge, it helped, I measured it with a tester on the battery, maybe the sensor just stopped correctly showing which generator is installed? There are usually 7 generators, 8, there are already relays on the brushes, they are new, but not working.

When the voltmeter is in the red zone, try removing the terminals; if it stalls, look at the diode bridge, look at the fuse on the box, it may oxidize!

Is the belt weak? The regulator relay could have died. Do not practice the so-called “terminal removal” technique (the consequences can be unpredictable); it is easier to measure the voltage with a tester.

Salon and trunk

The interior of the VAZ 2110 looks unprepossessing and stern. What's immediately noticeable is the simple two-spoke steering wheel without an airbag and the conventional dashboard with a few buttons. There are large buttons on the side of it, and there are large gaps in the center console. Ten does not support the required set of options compared to modern analogues. Only a clock, a stove, a niche for a radio and a 12-volt cigarette lighter with backlight are available. Only two people can comfortably fit in the back.

Depending on the configuration, the car provides:

air conditioner;
electric windows;
central locking.

According to user reviews, the main disadvantage of the model is isolation. The coating is very hard and constantly crunches. The car won't be perfectly quiet, but you can eliminate most of the noise with additional sound insulation. The trunk volume of the VAZ 2110 is 450 liters.

VAZ employees would not be themselves if they had made a Priora without flaws. The car is like a “rattle” - the door cards, the rear parcel shelf, the whistle from the door seals, the suspension (albeit in good condition) - everything rattles with different frequencies and volumes.

The body parameters in the new model remained the same, but the seats in the Priora became 15-30 mm higher. Passengers and the driver who are taller than average will not feel very comfortable. Priora owners have every chance to give up such a bad habit as smoking. Using an ashtray in a car is very difficult, but it snaps into place much better!

VAZ Priora salon

The trunk volume of the Priora sedan is 430 liters, the hatchback – 400 liters. The total length of the sedan is 4350 mm. (hatchback is 140 mm shorter), width – 1680 mm, height – up to 1508 mm. with a wheelbase of 2492 mm. The car is equipped with 14-inch wheels with 185/65 R14 tires.
