The car dashboard is the most important element of the vehicle, since it is through the instruments a dialogue between a car and man. To monitor the indicators and indicators of the instrument panel, you must constantly control the stability of the motor assemblies or, on the contrary, the changes occurring in them.

The battery light lights up always when the car's motor starts, however, when the engine is already working, and the battery charge mechanism is full, the indicator automatically goes out. That is, the fact that the battery charge indicator itself is absolutely normal, but the absence of its attenuation speaks of such a deviation in work, as an insufficient charging device. Read more about this in the article.

Cause of a malfunction in the battery, how to check and eliminate the cause

The tanned battery light bulb informs the car owner about the appearance of a malfunction. Failures that caused the absence of charging appear either in the battery itself, or in the car generator.

Detect deviations in the operation of the battery are quite simple, for which it is necessary to dismiss the battery that caused suspicions and set the working on its place. After that, compare the tests of the sample panels - if the indicator goes, you can conclude that the problem is in the battery itself.

It is worth noting that this problem may occur as a result of plate sulfate, which in some cases can be eliminated by repair. However, if the plates circuit occurred, the device is replaced.

Remember that the battery may well be working, however, discharge as a result of the fact that you left the inclusive car headlights or headlights when the motor is turned off. Analyze your own actions preceded by the indicators of the burning battery indicator.

If, after replacing the unit, the light bulb did not cease to burn, then the reason for this problem lies in the incorrect operation of the generator.

Faulty generator how to check whether the voltage generator gives

It is quite simple to determine the absence of voltage supply by the generator. Just when the motor is turned off, disconnect the wire from the battery and measure the voltage, the indicators of which should be located in the range of 12.5-12.7 V. Next, you must attach to the battery of the wire, turn on the ignition and again measure the voltage on the battery terminals. Device indicators should vary within 13.5-14 V.

Safety Safety when working with car electrical equipment

When implementing all the above manipulations, do not forget about the means of individual protection - necessarily put the rubber gloves.

How to check the generator wires

If, with increasing revolutions, the voltage decreases, the likely cause of a malfunction is the wear of diodes in a diode bridge or the "brushes" of the generator.

In the process of visual inspection, you can diagnose the presence of a belt attenuation or a break. Determine the belt tension by clicking on it with your fingers. If the belt begins to 1.5 centimeters and more, it is possible that the reason lies precisely in this. In addition, it is necessary to visually determine the presence of oxidation of terminals.

Also check the generator wires. They are capable of oxidizing and abrupt (there is a characteristic smell of Gary).

Troubleshooting that can be corrected by own forces

When the reasons are defined, it is necessary to eliminate them:

1. When weakening the battery, as a result of the long-term operation of the electrical appliances with a muted motor, charging will help restore its performance.
2. The rupture or loosening of the belt is eliminated by the complete replacement of the belt or adjusting its tension.
3. Oxidized terminals need to be cleaned with sandpaper shallow grain grain.
4. The wires and brushes of the generator are subject to replacement.

Troubleshooting what can only be done professional

However, there are also more global reasons for the failure of the device, such as: internal battery problems, circuit break, rotor wear, relay breakage, and so on. Such problems can only define a specialist.

Tips Prof.

If the indicator is on on the instrument panel, and rough noise is heard when the motor starts, you can conclude that the generator bearing is damaged. It is not necessary to exploit this generator without repair, otherwise vibrations can completely damage the rest of the unit. In addition, the shaft can fully bother.

It also happens when the battery battery is not only not charged, but also the vehicle network itself completely. The generator does not work, and the battery charge indicator is bright and constantly. In this case, the charge of the battery is enough for only several hundred kilometers. And this is at best. The reason for this is most likely a non-working voltage regulator. Even a new regulator fails quite quickly if the rectifier generator unit is faulty.

During the ride, you should listen to your car and look after the instrument panel readings. Such simple actions make it possible to identify problems in the work of the vehicle in the early stages, in order to avoid more serious consequences.
