The battery is not recharging (VAZ-2115)

The car has two sources of current - the battery and generator.

The battery is used to start the engine and to supply 12 V electric current to the starter and other consumers when the engine is not running.

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

If in instrument clusters the red battery discharge lamp is on, which means that the current is not flowing from the generator to the on-board network and the battery's energy reserve is being used up. This reserve is limited and depends on the capacity. If the battery was fully charged, you can drive to the garage without the generator, but it is better to try to fix the problem on the spot.
