Alternator And Drive Belt

The battery stores the electricity that the alternator produces and that is constantly consumed. The serpentine belt sometimes referred to as the fan belt, circles a number of pulleys on one end of the motor and supplies power to the alternator.

The crank pulley, which is mounted on the crankshaft is rotated as a result of the engine’s internal combustion which in turn turns this belt. As a result, the alternator pulley rotates, converting mechanical energy into electrical energy.

The alternator’s output must be managed to prevent overcharging the battery because it is directly fixed to the engine RPM at a certain speed. If you want to learn more about the alternator, check out our guides on where is an alternator located, the best brand of alternator, as well as whether can you jumpstart a car with a bad alternator.

Regulator

This is accomplished by the regulator, which modulates the magnetic field generated by the alternator’s rotor, the rotating center.

In essence, it alters the alternator’s efficiency, going from high efficiency at low rpm (engine revolutions) to poor efficiency at high revs while maintaining a reasonably consistent output power between 13 volts and 14.5 volts.

This power is chemically stored in the battery, which is a plastic cast container. They are rated according to how much power they can produce in the form of amperage or current. For example, diesel motors often require a larger battery than gasoline motors of the same capacity to start because they require more current.

Service Battery Charging System

The service battery charging system warning or alternator warning light indicates that the ECU has detected that the alternator is not charging the battery. This leaves the car functioning solely on its battery and gradually exhausting it.

The battery light comes on and off naturally with the functioning of the car. It turns on when the ignition system is turned on to demonstrate that it is functioning. But it must automatically be turned off once the car is running and the alternator is charging.
