Why the generator does not charge on the battery of the car - the causes and methods of repair. What to do if there is no charging, weak charging (the battery is discharged)? Generator does not charge VAZ 2107 injector

Today I decided to highlight one of the topics that is often worried about the owners of the VAZ 2106, and the remaining models of "classics".

Namely, it will go about problems with charging the battery or its complete absence.

Again, I want to immediately warn that all possible reasonsMost likely, I will not give, but those faced with, I will try to highlight below in the article.

Generator brushes wear

With insufficient length of the brushes of the VAZ 2106 generator, charging may not be enough or it will not be completely. In order to check the status of these parts, it is necessary if necessary. Let me remind you that the residual length of the brushes should be at least 12 mm. If when measuring it turned out that it is insufficient, this is a reason for replacing this part.

The outflow of the diode generator bridge

The brave of one or more diodes of the rectifier block can also cause a weak battery charging. From personal experience I can remember a few cases when, when you burn out only one diode, charging was insufficient and over time the battery had to recharge, as the generator could not do it fully. To accurately determine whether the reason can be diagnosed with a diode bridge, and in case of definition of a malfunction.

Fault Relay Charging

There are many cases that precisely because of the failure of the charging relay, it actually disappears at all. Long owners are looking for a reason until they change this detail of electricians on the VAZ 2106. It changes quite simply, as it is attached to only two bolts on the right side under the hood (usually).

More serious problems with the generator

If after the diagnostics performed, and the replacement of all those details that were written above, the charging did not appear, you should check the remaining parts of the generator, such as the stator and the rotor. More details about the diagnosis can be viewed in this article.

If found that on your VAZ 2107 there is no battery charging, measures must be taken immediately. Further operation of the car can lead to the discharge of the battery. You will have to either look for a fellow traveler, I agree to take a car on a tug, or call the evacuation service.

The theory "on the fingers": how everything works

On VAZ 2107, devices can be powered by 2 sources. The first is the battery, the second is the generator. The battery delivers energy when the engine is muted. It has a certain charge consumed as needed. The generator generates electricity, but only provided that the rotor rotates. That is - with the engine running.

Diagram of operation of the battery: 1. AKB, 2. Diode minus, 3. Diode extra, 4. Generator, 5. Diode plus, 6. Stator winding, 7. Regulator, 8. Rotary winding, 9. Condenser, 10. Mounting unit, 11. Control Light Bulb, 12. Voltmeter, 13. Ignition Relay, 14. Castle.

Control light

As can be seen from the scheme, a large amount is involved in the charging system composite elements And each of them can cause bad charging or its absence. To track the battery charging process dashboard The car is equipped with a light bulb.

If the system is in good condition, after the factory, the control signal is turned on. But when the motor goes into operation, the VAZ 2107 battery charging light is not lit. This means that the battery power supply is replenished from the generator. In parallel, the arrow on the voltmeter moves to the green sector.

Signs of lack of charging AKB:

• Twisted arrow charge battery VAZ 2107.
• The control signal does not go out. In some cases, the VAZ 2107 battery light is blinking.
• The voltmeter arrow after starting the engine does not go to the green zone.
• When the motor running the voltage on the battery should be kept in the 13.9 area.
• The permissible deviation in any direction does not exceed 0.3 V. Underwear of the VAZ 2107 accumulator within these limits is not yet terrible.

Voltage drop Up to 12 V says: With the generator, the charge does not go!

Where to start checking

If the VAZ 2107 battery icon does not burn, the voltmeter issues normal readings, but the battery at all is not charged, it means there is no (or insufficient) contact on the terminals. Their strength of their oxidation can cause the voltage from the generator to the battery simply will not come. Therefore, it is necessary to remove the terminals, thoroughly clean them, as well as the conclusions of the battery, after which they again connect the battery to the on-board network and check the performance of the recharging system.

In the case when the voltage on the VAZ 2107 battery is still below the norm, you need to measure it at the output from the generator when the motor is running. Large difference between testimony on the output and on the battery? Try cleaning the contacts and check the wire connecting the battery with the generator. Interrupted - requires replacement.

The next element that is checked is the generator drive belt. In case of relaxation, it will slip through the pulley, because of which the generator will not be able to develop the required amount of electricity. And even though charging and will be carried out (subject to the condition of the chain), but it will not be enough. In this case, the engine works, the voltmeter issues the norm. However, if the system is loaded a little more - for example, turn on the headlights - then the voltage drops sharply. Then, if the battery charge disappears on the VAZ 2107, this suggests that the tension belt is slightly stretched, it sinks. The belt should be tightened; If it was worn out during operation - replace. But it is impossible to drag: excessive strap voltage gives overload on pumps, generator bearings.

The third component of the chain, which is verified during primary diagnostics - fuse number 10 (in the fuse box). It is he who is responsible for filing a voltage to the battery: blocked the battery charging fuse VAZ 2107 - the system will not work.

If with terminals, a belt, the fuse is all right, the reasons for bad charging of the VAZ 2107 battery need to look next.

What else to check

1. Voltage regulator;
2. Rectifier generator block;
3. Diodes;
4. Generator for opening a winding;
5. Brush generator node;
6. Contacts on the findings of the generator, mounting block.

A malfunction of any of these elements leads to the fact that the recharging system is not working, and the VAZ 2107 battery is not charging.

We continue ...
Diodes are checked by a control light or a multimeter. If one of them breaks through, the entire rectifier will have to change.

To check the stator winding, you need the same device. The resistance between the fasteners of the rectifier block is measured. If there are no contacts between them, you need to replace either the winding or the entire generator.

The generator itself often fails in connection with the wear of the brushes. To check them, you need to remove the brush node and measure the length of the elements. If it is 5 mm and less, brushes are subject to replacement.

Almost all edited above the nodes of the system at failure are replaced, since repair is not subject to repair. Only some of the generator faults can be eliminated, but it can only make a qualified auto electrician.

Worst, if problems with recharging arose on the way. Due to the lack of recharging, it will eventually completely discharge. And even if you manage to find the cause of the breakdown and eliminate it, then start the motor starter will not work. You will be able to start the VAZ-2017 with a served battery only with a tug or "Tolkach".

What you need to consider choosing a new battery

According to the passport, the ACB is calculated for 3-5 years of active operation (actually goes less). Therefore, over time, it is necessary to buy and connect the VAZ 2107 battery instead of the failed.

By purchasing a new acb, a number of parameters and characteristics should be considered.
Battery type: served and maintenanceable. The first option allows you to check and replenish the level of electrolyte. This makes it possible to use the battery longer.

Next question: What power the battery on the VAZ 2107 will be the most effective. For this model, the battery capacity of 50-60 a * h is suitable. However, considering that modern cars Equipped with energy-intensive equipment, it is better to stay on more capacious batteries. In addition, carburetor models of vases require more powerful batteries - more consume energy when starting.
On the dimensions on the VAZ 2107 requires power sources with dimensions of 242 * 175 * 190 mm. The overwhelming majority are suitable for the sample market.

When choosing the battery, the place of residence of the "Seven" holder should also be taken into account. Those who live in the south can be purchased less powerful battery. Northerners are advisable to prefer an acb with increased capacity: in the cold the car starts with large energy consumption.

Confrontation of maliciousness

Due to the fact that the battery is not suiced, it is quite acute the issue of protecting the VAZ 2107 battery from theft. Open the hood on the "classic" is easy, so the thieves intently look at "seven".

Connoisseurs offer several options to prevent theft.

• Guarded Parking or reliable garage.
• Installation Alarm.
• Installation Castle on the hood. Immediately clarify: few have been going to this step. Need welded work, appearance It flies, but to hack the castle a professional is quite simple.
• Take away Battery with me. Laborious, uncomfortable, but effective. On the other hand, if the machine is left for a while, it is defenseless: remove the battery can both in the parking lot at the supermarket.

But all experts converge on the fact that the most reliable protection of the battery from theft of VAZ 2107 is complex. The combination of multidirectional measures will give the best results!

Video - Battery Protection from theft

Good day, dear reader. In this article, I will tell you as soon as possible about the principle of operation of the VAZ 2109 - 2114 generator and about the reasons for which the generator does not give charging. In order for a simple person to not studying electrical engineering, everything is clear, I will not delve into physics of what is happening and use scientific terms, but I will explain everything as they say "on the fingers." So, let's begin!

The principle of operation of the VAZ 2109 - 2114 generator.

In order to understand why on the VAZ 2109 - 2114, the generator gives little charging or does not charge at all, it is necessary to understand how it works and know the principle of his work.

The generator consists of five main parts of the pictures shown below: anchor - 5, stator - 6, a relay regulator in a pair with brushes - 10, diode bridge - 9, housing - 3.7.

The principle of work is as follows:

1. from the battery to the diode bridge (9) There is a plus wire and diode bridge (9) Connects with mass through the case (3,7) Generator
2. voltage through the diode bridge (9) serve on stator (6) The generator and the stator appears a magnetic field
3. when the car started, the engine, with a belt drive, turns the rotor (5) Generator
4. in the rotor (5) rotating in the magnetic field of the generator (6) There appears
5. current removes with rotor brushes (10) and through the relay - regulator (10) served on the car battery.

Failure to comply with any of the items leads to the malfunction of the VAZ 2109 - 2114 generator.

The reasons for which the VAZ generator 2109 - 2114 does not charge.

To find the reason for which the VAZ 2109 2114 generator does not work or does not exercise, it is necessary to check for the serviceability each of the items describing the operation of the generator.

Point first: the diode bridge does not come plus from the battery.

The cause of the malfunction in such cases can be the wire or place of its connection with a diode bridge or battery. Try cleaning the connection terminals, and if it does not help, then ring the wire.

Bad contact with the minus wire is not considered, since in such cases the engine would not start at all.

Item Second: Diode Bridge and Generator Stator.

After checking the diode bridge, when it good job, Nick the stator winding. To do this, you choose the transverse mode on the multimeter and apply the probe to the first and second contact of the stator, and then to the first and third.

Clause Three: Vaz 2109 - 2114 generator belt.

On the carburetor version of the vase was a thin wedge belt, and on the injection models there is a wide belt with the cores, but the principle of work does not change. Charging may not be bad due to belt slippage. Such a fault is manifested strong whistle belt. Also, the belt can begin whistle when you turn on the consumers of energy such as headlights, heated glass, fan stove, etc. If you hear the leaf of the belt, try to replace it in the near future. This is one of the reasons why the VAZ generator 2109 -2114 does not give a charge.

Item Fourth: Anchor Generator VAZ 2109 -2114.

Anchora, as in the stator should not be broken. Clean it applied to the multimeter probe to the climb paths.

If the anchor is not nicknamed, it should be replaced.

Point Five: Brushes with a relay - regulator.

Brushes Generator VAZ 2109 -2114 Over time, erased about the armature path. If their length is less than 5 millimeters, they are not capable of pressing the anchor tightly, thereby not providing the charging of the VAZ battery.

But it happens that the relay - the regulator fails earlier than the brushes are erased. To check it, you will need:

• 12 volt light bulb
• car acumulator
• two batteries of 1.5 volts
• several wiring

We connect the light bulb and the battery to the relay -regulator as shown in the figure below. In this case, the lamp should burn.

Now add two batteries to the diagram, as in the figure below. Now the light should not burn.

If the light lights up in both cases - the relay - the controller needs to be changed.

Now you know all the main causes of the malfunction of the VAZ 2109 generator - 2114. If you have any questions - leave them in the comments!

If the generator stopped giving charging, there is nothing good in this. It is necessary to immediately begin the search for the cause of such a malfunction. Otherwise, all your electrical equipment will be without food, and the battery will soon be completely sighing.

If the generator works well, then the battery will not need additional charging with special devices for many months, sometimes even years. A minimum of 60% of charge will be stable in the battery. Thus, the batteries constantly replenish the charge of the charge due to the operation of the generator.

What is standing on the VAZ 2110

For cars VAZ 2110, it is envisaged to install two types of generators, depending on installed engine.

1. For carburetor models, the generator is installed with number 9402.3701.
2. If the engine is injector, then catalogue number The generator used will be 3202-3771. It has a polyclinic belt.

Regardless of the type of engine installed and the generator, respectively, malfunction on devices are the same, because the procedure for checking and repairing in both cases is identical.

Fault

There are two main reasons because of which the generator ceases to properly adequate.

Cause	Features
Device overload	It happens to those who love to establish numerous optional equipmentthat is powered by a generator, that is, it requires electricity. These may be speakers, electric pumps, video devices, etc. The standard generator for such loads is not designed, therefore loses efficiency
Inconsistency of the battery and generator	To ensure the operation of electrical equipment, additionally installed on the car, many decide to set a more powerful battery with a regular generator. The inconsistency of capacity leads to the fact that the generator ceases to ensure proper charging of a more powerful battery. So it's simply lacking for this resources

Which charge gives the generator

Many are interested in the question of how many generator should issue for normal operation.

Here the parameters directly depends on the current state of the car.

• If the engine is cold, only turns on, then the voltage is normal 14.1-14.4 volts;
• If you check the voltage after long trips under traffic conditions, then the generator will already be less than, about 13.9-14.1V.

Search for faults

No charging can be caused by a broad list of reasons why we will talk about today.

These are reasons:

• Weak contacts;
• Winding cliffs;
• Circuit on the rotor case;
• Mixless closures;
• Mechanical breakdowns;
• Closing the plus clip on the housing;
• Closure in the phase winding;
• Circuit of the stator on the housing.

Consider these situations in more detail to determine the true cause of the breakage specifically in your case.

Start by disconnecting all the additional equipment in your car, which is not provided standard complete set - DVR, navigator, audio system, etc.

1. Measure the return of the current when the car is cold, it does not work and all life support systems are disconnected. If the return will not be at all, it's good. But it rarely happens. Almost always on dozens may be insufficient contact, some kind of closure, because of which the return is there, but small. Where worse, if the return is impressive and leads to the discharge of the battery in one night, spent in the parking lot or in the garage.
2. If everything is normal, there are no strong current leaks or they are minor, and the battery has retained its charge, then you can return all the devices to the places that were installed additionally.
3. Perform recoil check. If the devices show an active leakage then, then the reason lies not in the battery, is not associated with the generator. The culprit of the problem is one of the devices connected additionally.
4. If at the same time the return is not observed, then you need to carefully inspect the generator.
5. Sources of trouble that can lead to the failure of the generator, there are many. These include:

• Insufficient contact between rings of rotor and brushes;
• In the winding of the excitement there was a breakdown;
• There was an intersless closure on the coil of the excitation winding. In this case, the generator will buzz and warm much;
• The excitation winding closes on the rotor case;
• The stator closes on the body;
• There is a break in the phase winding of the stator;
• Diodes in the rectifier block made their way, that is, a diode bridge;
• Closed plus on the housing;
• Mechanical malfunctions appeared.

Solution of problems

1. Weak contact. The relaxation of contact can occur due to contamination, oil contacts on the brushes, contact rings. Also, contact may worsen because of the shrinkage of springs, which are put on the brushes, or brushes depended. Such phenomena lead to an increase in excitation resistance and sometimes can break the chain. To eliminate the problem, it is sometimes enough to simply treat the surfaces with a rag in gasoline. If the brushes were worn, it is better to replace them. In parallel, check the state of the springs, rings. Rings are oxidized, therefore treat them with glass sandpaper.

1. Winding broke. If this happens, charging acb. To determine the problem, put your hand on the battery. In the presence of a break, the device will begin to warm up. If you want more accurate check, then disconnect the end of the excitation winding from the brush and connect to it and the wiring of the Wires of the battery using a voltmeter or light bulb. In the presence of a break, the lamp will not light up, and the voltmeter arrow will not move from the place. Check each coil separately to determine which one does not give the generator to work. Internal coils are replaced, and internal solders.

1. Circuit between the turns. Mixing closure can occur in any coil of the excitation winding. If such a situation happened, the winding will begin to warm up, the excitation current will increase. To check, be sure to measure the resistance indicators of each coil. To do this, you will use a voltmeter.

1. Circuit on the rotor housing. Such a breakdown leads to the fact that the entire excitation winding closes. The generator stops its work. The most common area of \u200b\u200bclosure is the places of bringing the ends of the winding to the rotor rings. Use a 220V light bulb for check. One wire should be connected to any contact ring, and the second is on the core or the rotor shaft. If the closure is available, then the light will turn on. Operating a car with such a generator is impossible. It is necessary to isolate or completely replace the faulty winding. The first option is suitable only to get to a hundred and carry out full repair.

1. Circuit on the phase winding. This kind of problem arises due to the fact that the insulation is destroyed, which is existing between the coils of the stator coil. If this happened, the generator will begin to warm up, the battery will not get a sufficient charge, as this happens at high speed crankshaft.
2. Circuit of the stator on the housing. As in the case of the other listed closure options, in this situation the generator begins to overheat, buzz, its power drops significantly. To check, you will need a 220V light bulb. One wire is connected to the core, and the second - on the output of the winding. Any. If you have a closure, your light bulb will light up. To resolve the problem, it is enough just to replace the failed coil.
3. The positive clamp closes on the body. Such a fault is unpleasant by the fact that it does not just overheat your generator. Also, due to this closure, there is a breakdown of diodes of the rectifier block. From there, the problem passes to the battery, which can simply close. Not rare the closure led to the complete output of the battery. Although most often he is just completely discharged.
4. Mechanical problems. If you take into account all possible mechanical problems of the generator, then the belt stretching in the first place in the first place. This is the most popular breakdown in the case of VAZ 2110. If this happens, the pulley will begin to seriously overheat, rechargeable battery There will be insufficient charging. Not an excessive event is to verify the quality of all contacts, the presence of bugs of compounds and other possible mechanical problems.

When problems detected with the generator, immediately proceed to measures aimed at eliminating breakage. If there is no experience, contact exclusively on proven maintenance stations.

The generator is the heart of the electrical system of your car. As if the main organ of a person, it provides nutrition of all devices, devices. Because it should be treated very carefully and when problems occur, do not tighten with repair.

Rechargeable contact

In order for the use of your "seven" to benefit and pleasure, not chagrin, you need to have a well-charged battery (AKB) on it. The battery over the operation of the car is constantly being recharged, for which the VAZ 2107 generator generates a charging voltage. Like any system in the car, the battery charge system sometimes gives a failure and then charging disappears. Therefore, often in the course of operation, the question is asked why there is no battery charging. The owners of the car in this case will be useful to know why the generator does not charge or why there is no charging on the VAZ 2107.

A bit of theory

During operation, the hood battery is charged with a constant voltage at 13.6-14.2 in the on-board network of the car. For proper operation of the car and its systems, this voltage is supported by the battery itself before the generator rotor does not start rotating with a frequency of 800-900 rpm. Then it produces electricity sufficient for normal work Car and charging acb. With different engine operation modes, when the engine speed frequency is changed, the frequency of rotor rotor is changed, which leads to an increase in the voltage at the generator output. To maintain 13.6-14.2 V voltage network in the on-board network network, the voltage regulator (PP) is turned on, which, with an increase in voltage in the network, above the nominal reduces the current going on the generator excitation winding. The magnetization of the poles of the rotor decreases, which leads to a decrease in its output voltage.

The reasons for the fact that the generator does not charge the battery are associated with the elements of the excitation chain or the output voltage circuit from the generator to the battery, including the generator parts.

Ignition relay

When the ignition turns on, the lock includes ignition relays. At the same time +12 in pass through the contacts of the relay and the fuse number 10 of the mounting unit, then submitted to on-board network And on the output of the battery charge lamp and charging sensor. After they go through a diode, the mounting unit (plugs sh5-sh10) are fed to the 61 generator plug of the generator 37.3701, which are installed on the VAZ 2107 from 1988. Further +12 B falls on the terminal of the built-in RR and through the brush and the contact ring on the winding Excitation - generator starting excitation. With an increase in the frequency of the engine speed, and with it the generator rotor, the phase voltage increases, and it increases the voltage on the excitation winding and at the output diode of the battery charging light. When the output phase voltage is reached to +12 in both conclusions of the battery lamp, the voltage is aligned, and due to the lack of voltage difference it goes out. In this case, the VAZ 2107 generator generates a voltage of more than 12 V, which charging the battery.

Electrical equipment of the car VAZ 2107 The injector differs from the carburetor carburetor carburetor only by the presence of a part of the equipment that ensures the system of power supply and does not affect the battery. Rather, on the contrary - malfunctions in the Account charge system may affect the operation of the ECU of the injection engine.

Management of powerful electricity consumers is carried out using electromagnetic relays included in the network. Consider ways to eliminate the battery charge faults for both injector and carburetor engine.

How to determine the absence of the battery

Checking Account Charge

The easiest thing is the lack of charging to determine with the help of car devices, that is, the control lamp of charging and sensor (voltmeter) on the instrument panel. The arrow of the sensor must be in the green sector, and the battery lamp with the engine running does not burn. Otherwise there is no charge.

But best way is the voltage check on the battery multimeter. If there is a charge, the voltage on it lies in the range of 13.6-14.2 V, and when there is no charge, it will only be 12 V voltage (± 0.6 V). Do not remove to check the terminal from the battery in order to avoid the failure of RR, ECU and others electronic devices On your car.

In order to detect and troubleshoot the battery charger, you must use the following tools:

• control lamp 12 V;
• multimeter with a measurement range up to 60 V AC and DC voltage;
• screwdriver with flat sting;
• curious screwdriver with crust sting;
• passatia;
• emery skar.

Trouble-shooting

• The sensor (on-board voltmeter) shows the presence of charge, the battery light is off, and the battery sat down, not there is a charge And the checking of the multimeter shows the voltage when the engine running on the drive terminals is only 12 V.

First you need to clean the battery terminals and the inner surfaces of the wire terminals on the battery. If this does not give the result, the voltage at the outlet of the generator (terminal "30") is measured relative to the "mass" when the engine is running (the rotational speed of the crankshaft is 1000-1200 rpm). If the voltage is noticeably different, the contact of the terminal "30" with the wire is preparing, the wire itself from the generator to the battery is nicked. In extreme cases, this wire changes.

• The control lamp and the sensor (onboard voltmeter) show the presence of a charge, and the battery sat down, but the checking of the multimeter shows on the battery terminals normal tension 13.6-14.2 V. When turning on a large load (for example, far Light Headlights) The sensor arrow falls into the White Scale Sector.

Such symptoms can be with a weak tension of the generator belt. It is necessary to measure the tension (with an effort on the belt at 10 kgf, the deflection should not be more than 12-17 mm), and if the tension is weak, the belt is stretched or replaced.

The reason can also be a breakdown of one of the negative diodes, the brave of one of the positive diodes of the rectifier or a break of one of the phase stator windings. For disabled Engine Negative diodes are checked: the "+" battery terminal from the car is disconnected and the control lamp is connected to it. The leg of the lamp is triggered to each of the three fastening bolts of the rectifier block of the generator. If the lamp is burning, connected to the bolt negative diode is broken.

To check the positive diodes, the "+" terminal is connected and disconnected from the body of the "-" terminal, to which the control lamp is connected. Again, the lamp is triggered by the lamp to each of the three fastening bolts of the rectifier block of the generator. The burning of the lamp also means sample of a positive diode. If there is a multimeter, simply measure the resistance of diodes in polarity, in which the diode must be locked: for negative diodes "+" to bolts, and "-" - to the housing, for positive diodes "+" to the terminal "30" of the generator, and " - "- to bolts. The diode rectifier with a punched diode is completely replaced.

The breakdown of one of the branches of the stator winding is checked by nicking them with a multimeter or "control" with a battery between two bolts of the rectifier block. The lack of contacting any winding with each of the two remaining speaks of its cliff, and the generator is subject to repair or replacement.

Check the generator brushes

Another reason can be the wear of the generator brushes. A brush knot with PP is removed. If the brushes are less than 5 mm long, the node changes to the new one. If the brushes are not worn, they should be examined by the possibility of skewing and "sticking" in the housing wells.

• The charge lamp when turning on the ignition does not light up. Charge sensor does not work and other control devices. Charging generator did not give.

The cause of this malfunction - blocked fuse F10 (10 A). If after replacement nothing has changed, they are looking for reasons in the lock or relay (if it is installed) ignition.

• When the ignition is turned on, the control lamp does not burn. Charge sensor and other control devices work. Charging generator does not give.

The wire from the 61 generator plug is disconnected and closes on the mass. If the lamp is on when the ignition is turned on, the generator excitation winding is faulty or there is no contact in the plug itself. The surfaces of the pins are cleaned, the fibers of the plug connectors are pressed, connected. It is checked again and if the charge lamp is again not lit, the plugs sh5-sh10 of the mounting unit and pins in the plug connector with the instrument shield are cleaned. If the result is not, it means that the lamp itself burned. To replace the light bulb, the flap of instruments is removed, the cartridge is removed from behind, the lamp changes.

• The battery lamp when turning on the ignition lights up. When the engine is running on idling The charge lamp burns dimly, charging disappears or there is no charging at all.

The reason may be bad pin pin connecting the wire connections to the instrument shield. It is attached to rivet and often oxidizes. If you solder it to the road path, this fault is eliminated. Also, a loose contact in the connection places along the path of the wire from the shield to the 61 generator plug gives the same symptoms.

To check the excitation winding on the breakdown of the multimeter, the rotor rings are touching the rotor rings when the brush node is removed - the working winding shows a small resistance. When you touch one probe to the ring, and the other to the shaft or the rotor body check the presence of a closure of the winding on the mass. To check the voltage regulator, the "+" battery is connected to the upper contact, and to the left - "-" and measure the voltage on the brushes. It should be 12 V. If not - the relay is subject to replacement.
