2. What is the Role of the Alternator in Your Vehicle?

Modern cars rely heavily on electrical power for various functions. The alternator plays a crucial role in this system. It takes power from the battery and amplifies it to support all electrical needs while the engine runs. This includes systems like the radio, power windows, door locks, and advanced features such as anti-lock brakes (ABS), which require continuous power for sensors, control modules, and pumps.

The alternator consists of a magnetic rotor and copper windings that generate alternating current (AC). This AC is then converted to direct current (DC) by a set of diodes in the rectifier, which is the type of electricity that car devices use. The alternator also regulates voltage output to prevent overcharging and ensure a consistent power supply. A properly functioning alternator maintains an output of 13.5 to 14.5 volts. If the alternator fails to maintain this voltage, produces unusual noises, or delivers the wrong type of current, it needs replacement to avoid further electrical issues.
