On cars VAZ-2101,-2102 and their updatings was applied the three-phase generator of an alternating current of type Г-221 (fig. Generator G-221 see) with the built in rectifier. To the middle of 80th years "negative" gates (diodes) of the rectifier were запрессованы in a cover 1, and "positive" – in the separate plate attached to a cover.

From the middle of 80th years at generators G-221 all gates are in not folding выпрямительном the block 2 consisting of two plates. In case of damage of gates the block is replaced with the new.

The regulator 6 (fig. the Scheme of connections of system of the generator see) supports pressure of the generator at level 13,2–14,5. Serviceability of the generator is checked by means of a control lamp 12 in combinations of devices and the relay 13.

At ignition inclusion, when the engine (and therefore the generator) yet does not work, through relay contacts proceeds a current from the storage battery, and the lamp burns. After start-up of the engine and at movement of the car the lamp should die away, as under the influence of the straightened phase pressure of the generator the relay anchor should be drawn to the core and disconnect relay contacts.
