Electrical components of a VAZ car
* Battery – provides electricity to the starter, ignition and other electronic systems.
* Generator – converts the mechanical energy of the engine into electrical energy to charge the battery and power electrical systems.
* Starter – starts the engine by converting electrical energy into mechanical energy.
* Ignition system – generates a spark to ignite the air-fuel mixture in the engine cylinders.
* Lighting system – provides illumination of the road and vehicle for other road users.
* Light signaling – informs other road users about the driver’s intentions (turning, braking).
* Dashboard – displays information about engine operation, speed, fuel level and other parameters.
* Controllers – control various electronic systems such as air conditioning, power windows, etc.
