The electrical equipment of the Gazelle vehicle is implemented according to a single-wire scheme: the negative terminals of the power sources and consumers are connected to the "ground" - the body and other units of the vehicle, which act as the second wire.
The scheme is divided into two parts for better viewing
Fig. 1. Scheme 1. Electrical equipment of GAZ-3302 vehicles with ZMZ-4025 and 3M3-4026 engines: 1 - direction indicator; 2 - headlight; 3 direction indicator repeater; 4 windshield washer motor; 5 - underhood lamp; 6 rear seat lighting lamp (for vehicles with two rows of seats); 7 - cabin lighting lamp; 8 driver signal buzzer; 9 driver signal switch; 10 platform lighting lamp; 11 generator; 12 voltage regulator; 13 - fuse box in the engine compartment; 14 starter relay; 15 spark plug; 16 transistor switch; 17 Ignition distributor; 18 Ignition coil; 19 - lower fuse box; 20 - rear seat lamp switch (for vehicles with two rows of seats); 21 - horn; 22 rear fog light switch; 23 - central light switch; 24 idle speed control unit; 25 idle speed control system switch; 26 - electromagnetic valve; 27 ignition switch (lock); 28 starter; 29 storage battery;
On-board network – direct current, with a nominal voltage of 12 V.
A combined ignition switch, consisting of a contact part and a mechanical anti-theft device with a lock, serves to switch the main circuits of the car.

When the engine is not running, all consumers are powered from the battery via a remote-controlled switch, and after the engine is started, from the alternator with a built-in voltage regulator.
When the alternator is running, the battery is charged.
