The battery and the alternator are closely connected in the operating process, because to start the engine, the current from the battery is supplied to the appetizer. Subsequently, the voltage begins to flow from the generator, which is powered by an engine in operation.

If the ON -Board witness that symbolizes the battery is turned on when it does not need, this indicates that the battery is not loaded by the alternator.

The most common causes:

• Defective operation of the regulatory relay;
• Defect of the deck of diodes;
• The broken alternator strap, weak or slide from the position;
• Burnt fuses;
• Incorrect contacts to the battery terminals, at the exit of the generator, on the table;
• Short -circuit in the generator circuit, brushes or broken alternator supports;
• Problems with contact.

The first thing that is done when the LED is turned on during the walk is to control the charge level to the battery terminals. A multimeter is used which should normally indicate 13.5- 14.3.v.

If there is no current, the tension will be 12 V.

If the indicated tension is 14 V but pregnancy decreases, it is possible that the problem is at the belt of the alternator, respectively being weak.

Possible causes depending on the car model

The most common causes of ignition of the on -board witness are the battery and the generator. If you are traveling and you don’t have a verification tool, the simplest process is this:

Exit the car with the engine on, lift the hood and open the least from the battery. In the event that the car continues to go, it means that the generator is good and the defect comes from the battery.

A battery can be examined and visually and the first thing you need to inspect are the battery terminals. If they are sulphates (white deposits on the terminals), more than safe, these are imperfect contacts or even the lack of contacts.

These are clean and things should go to normal.

If you have identified the reason for the activation of this indicator, it is time to start remedying.

The specialist’s advice in remedying the problem:

• You can delete weight loss or break it by adjusting the degree of voltage or by resorting to its replacement;
• To clean oxidized terminals it is sufficient to clean with a small granulation with small granulation;
• In the event that the battery is downloaded following the prolonged operation of electrical appliances with the interrupted engine, simply recharge it;
• In the presence of different internal damage it is necessary to contact a specialist.

Conclusions:

By carefully monitoring the readings on the dashboard, it is possible to independently identify the problems in the operation of the vehicle at the beginning and you can avoid serious consequences. We activate your attention that in such situations it is good to face authorized services.
