The battery does not charge

There are two sources of current in a car - a battery and a generator. The battery is used when starting the engine and for supplying the starter and other consumers with an electric current of 12 V when the engine is not running.

When the engine is running, the main current source - the generator - provides electric current to all consumers, including the ignition system, and charges the battery.

If the red battery discharge warning light is on in the instrument cluster, it means that no current is supplied from the alternator to the on-board network and the battery energy is being used up. The operation of a car with a burning battery discharge warning lamp is unacceptable, since sometimes the cause of the lamp to light up can be a short circuit in the wiring, leading to a fire in the engine compartment of the car. Stop the car, turn off the engine and find out what malfunction caused the lamp to light up. If the cause of the malfunction is not a short circuit and the battery was fully charged, you can drive to the garage without a generator, but it is better to try to fix the problem on the spot.
