In cases where, for some unknown reason, the brightness of the headlights while driving "leaves much to be desired", then in all likelihood it is required to check the serviceability of the generator of the VAZ car.

Instructions
Step 1
Checking the performance of a car generator is performed on a running engine, increasing its speed to 3000 per minute. Along with this, all electricity consumers are turned on: high beam headlights, a heater for maximum power, and others.
Step 2
Having fulfilled these conditions, a voltmeter measures the voltage at the battery terminals. The readings should be in the range of 13.2V to 13.6V. The indicators depend on the type of generator installed in the on-board network of the machine. With the electrical appliances turned off, the generator must generate 14.8 volts. If the measurement data indicate violations, then it is unlikely that it will be possible to avoid its repair.
Step 3
A change in the voltage mode generated by the generator is often associated with an open or short circuit in its windings, with a malfunction of the brush unit and voltage regulator, with excessive contamination of the rotor collector rings, as well as with a malfunction of the rectifier unit.
It is possible to identify a malfunction of a separate diode of the rectifier unit only when removing the generator and aluminum plates with rectifiers dismantled from it, by making measurements with an autometer and identifying "broken" diodes.
