Frequency: Every 15,000 km, check the operation of the generator, lighting, light and sound alarms, control devices, wiper, washer, tailgate glass heating, ignition system.
At service stations, the operation of the generator is checked on the stand. In garage conditions, you can approximately estimate its work by the strength of the headlights.
If you detect a malfunction of any electrical device of the car during operation, immediately contact the specialists.
Start and warm up the engine. Turn on your low beam headlights and note how bright they are. Bring the crankshaft speed to 2000–3000 min–1 (if there is no tachometer in the instrument cluster, press the accelerator pedal so that the econometer needle reaches the yellow zone). If at the same time the brightness of the headlights increases, the generator is working normally. During the test, do not turn on other current consumers.
