What to do if the battery lack of charge lamp is on on a Lada Kalina


If the battery charging light comes on, the driver begins to worry. And the reason for this is serious - the battery capacity is unlikely to be enough to cover a significant mileage. And the reason that the lamp comes on may be a breakdown of the generator, battery, or a malfunction in the on-board network. All these factors should be considered more carefully so that in the event of an unforeseen situation, the breakdown can be quickly eliminated. To monitor whether the battery is charged, a special lamp is installed in the dashboard. It lights up if there is no charging.

How does a generator work?

Before you understand why the battery charging light comes on, you need to understand the principle of operation of the generator. Any car has two power sources. This is a generator and battery. They are connected in parallel. Therefore, when the engine is running, the generator supplies voltage to the battery and charges it. Moreover, there is one peculiarity. Regardless of the speed, the voltage at the generator output is always the same.

To stabilize it, a relay regulator is installed. Older cars used electromechanical-type designs. Modern ones use exclusively semiconductor ones. The lamp, which is installed in the dashboard, is included in the power circuit of the voltage regulator. It essentially serves as a fuse. To understand the essence, it is necessary to thoroughly study the principle of operation of the voltage regulator relay.

Can the check light come on because of the battery?

I forgot to turn off the lights. Despite the fact that the security guard from the parking lot called me, I still didn’t go straight to the parking lot and didn’t turn off the lights. The call came just as I was driving with my wife to meet old friends. After the meeting, I simply forgot, 3 beers don’t count.
