As the name suggests, the regulator is to adjust the power generation of the generator, because the speed of the automobile engine is not certain, and the generator is driven by the engine, in order to stabilize the electricity emitted by the generator, it is necessary to adjust the internal magnetic field current of the generator, the current adjusted when the speed is low, and the current adjusted when the speed is high, so that the generator can stabilize the output.

Of the 5 wires of the regulator, 1 of them is the power supply B of the regulator, which is controlled by the ignition switch and is equivalent to the induction line that monitors the size of the generator, and the current from the regulator is small when the voltage is high, and vice versa.

The second is the tie wire E, which is the most basic. There must be a fire wire and an iron wire when using electrical appliances.

The third is the neutral point n, which is connected to the neutral terminal post on the generator, and the voltage is half of the power generation voltage when the generator is working normally, and the function is to control the charging indicator.

The 4th is the charging indicator line L, the charging indicator light is turned on from the ignition switch, sent in from the instrument power supply, and then connected to this line, it passes through the internal iron of the regulator, and the charging indicator light is lit; After the power is turned on, there is an electric control at the neutral point, so that the voltage on the regulator L rises, and the potential at both ends of the charging indicator is about the same, and the light goes out.

The fifth root is the magnetic field f, which is also connected to the generator, and it is this line that makes the generator have a magnetic field current and can generate electricity.

To judge the quality of the regulator, method 1, the generator does not generate electricity, there is no power at the magnetic field end of the test lamp, and the regulator F has no electricity, but B has electricity, and E is normal, that is, the regulator is broken, and it is replaced. Method 2, the generator power generation is too large or even higher, then the regulator is generally broken, and it is replaced.

Hello dear! Thank you for waiting, if the car generator is damaged, this is a suggestion that you should consider replacing it directly. Like the current generator of many models can not be repaired alone, and like the internal damage of this generator, there are mainly three aspects, one aspect is the internal mechanical bearing damage, this bearing can be replaced separately.

The second aspect of damage is the damage of the internal electrical components, like the internal rotor stator is generally not repaired separately. The third aspect is that some regulators or rectifiers are damaged, which can also be repaired separately, but it is more troublesome and it is not recommended to repair it separately. Kiss!

Symptoms of a broken generator regulator: unable to supply the battery with complete and continuous power, resulting in a gradual decrease in battery power and even failure to start the car. The standard voltage of the battery is 12V, and it can reach 14V (engine working state) in a fully charged state.

As the name suggests, the regulator is to adjust the power generation of the generator, because the speed of the automobile engine is not certain, and the generator is driven by the engine, in order to stabilize the electricity emitted by the generator leakage cavity around the left and right, it is necessary to adjust the internal magnetic field current of the generator, the current adjusted when the speed is low, and the current adjusted when the speed is high, so that the generator can stabilize the output.

At present, alternators are widely used in automobiles, and the following points should be paid attention to when using them:

1. Clean the dirt and dust on the surface of the generator frequently, and keep it clean and well ventilated;

3. The tension of the transmission belt should be appropriate. Too loose, easy to slip and cause insufficient power generation; Too tight, easy to damage the belt and generator bearings;

4. When installing the battery, do not install the wrong one, usually install the positive wire first, not the iron wire, otherwise it is easy to burn out the diode;

5. When the integrated circuit regulator is used, the ignition switch should be turned off immediately when the engine is not running;

6. It is never allowed to use the "scraping" method to test whether to generate electricity;

7. When the generator fails to generate electricity, it should be eliminated in time, otherwise it will cause more serious failures.

If the car generator is broken, it cannot be repaired, and it must be replaced with a new one.

The generator of the car is a very important part of the car, after starting the engine, the generator is to supply power to the electrical equipment of the whole car, and the generator will also charge the battery. If the generator breaks, the engine won't work properly.

The ignition system and fuel supply system of the engine all require electricity, and the engine's computer and sensors also need electricity when working. When the generator is damaged, the battery will be switched, and the engine will turn off and the car will break down when the battery is dead. If the generator is damaged, it needs to be replaced with a new one immediately.

Failure Impact:

The failure of the generator itself is not only an external influence, but also the motor itself will have a variety of failures, especially mechanical failures, which is the main factor in the problem of the generator, because it will make the generator overloaded, or directly do not rotate. There is also the destruction of the insulation of the motor, short circuits, and the failure of the cooling fan.

Let the motor overheat, there are a series of problems such as the air duct being blocked, the wear of the bearing, etc., but in addition to some big problems that need to be replaced with a new motor, small problems can be dealt with by cleaning, lap key maintenance. But when repairing, we must see clearly, because now many maintenance workers have become simple stevedores, big problems are changed, small problems are also changed, try to find a familiar maintenance place to deal with the bright bucket.

It can be disassembled and repaired, and there are a very small number of generators that cannot be repaired and can only be replaced.

In the process of normal operation of the engine, the automobile generator mainly plays a role in supplying power to the electrical equipment of the whole vehicle, and at the same time charging the battery. However, the generator may also fail during use, and if the generator is broken, even if some parts are broken, other parts are actually close to the end of their service life.

A broken generator regulator can lead to symptoms such as unstable generator voltage, high power generation, and generator failure to generate electricity. The function of the regulator: when the speed of the generator changes, the generator voltage is automatically controlled to keep it constant, so as to prevent the generator voltage from being too high and burning out the electrical equipment and causing the battery to be overcharged, and also to prevent the generator voltage from being too low and causing the electrical equipment to work abnormally and the battery from being charged insufficiently.

The generator voltage is unstable due to the bad generator regulator, such as the power generation is too high, the battery is easily damaged, resulting in the overcharge of the battery and affecting the life of the battery, and it will be difficult to get on the car after the battery is damaged.

Hello dear! There are two situations in which a broken car generator is repaired or replaced:1.

It can be repaired, and it can be repaired in a small area, and it can only be used after replacing parts or repairing it again. 2.It cannot be repaired, the scope of damage is relatively large, and it cannot be repaired, so it needs to be corrected and replaced in time.

What are the main functions of a car generator? The main function of a car generator is to generate electricity. After the vehicle is started, the engine generates electricity, which is supplied to the battery for storage, which is used by the relevant electrical components on the vehicle.

It is a very important part of the motor vehicle, and once damaged, the vehicle cannot be started. Do generators need to be replaced regularly? If you don't need to work regularly, you just need to check it regularly in the car mill during use to see if there is any problem.

If there is damage, you need to repair it. If it cannot be repaired, it can be replaced, which does not affect the normal use of the motor vehicle and brings good use results.

If the regulator of the generator is broken, the voltage of the generator will be unstable, or the generator will not generate electricity. The generator is an important part of the car, and when the engine is not started, it is the battery that provides power to the electronic equipment in the car. After starting the engine, it is the generator that supplies power to the electronics in the car, and the generator also charges the battery.

If the regulator of the generator is broken, there will be a situation where the generator voltage is unstable, or there will be a situation where the generator does not generate electricity.

The generator is an important part of the car, and when the engine is not started, it is the battery that supplies power to the electronic devices in the car. After starting the engine, it is the generator that supplies power to the electronics in the car, and the generator also charges the battery.

Generators are driven by engines.

When the engine is working, the speed change range is very large, and the speed change range of the generator is also very large, which requires a regulator to stabilize the voltage of the generator.

If the regulator is broken, the generator will have an unstable voltage or even no power generation.

If the voltage of the generator is too high and exceeds 15V, it is also a faulty regulator.

If the generator regulator is broken, the only way to do this is to replace it with a new one.

Generators can also fail after long-term use, and generators are considered to be a consumable part. If the generator of the car does not generate electricity, first check the regulator and then check the generator.
