What system produces electrical power while the engine is running?

The charging system is responsible for producing electrical power while the engine is running. This system is primarily composed of the alternator, which converts mechanical energy from the engine into electrical energy. When the engine is operating, the alternator generates electricity to power the vehicle's electrical components and recharge the battery. This process ensures that all electrical systems function properly and that the battery maintains a sufficient charge for starting the engine and powering accessories when the engine is off.

The ignition system, on the other hand, is responsible for igniting the air-fuel mixture in the engine's combustion chamber but does not generate electrical power for the vehicle's electrical systems. The starting system is involved in starting the engine initially and includes components like the starter motor, which is activated when you turn the key in the ignition. The fuel system manages the delivery of fuel to the engine but does not play a role in generating electrical power.
