Alternators: Giving Your Car the Volts it Needs

Your vehicle’s charging and starting system is a complex web of sensors, regulators, storage systems, and generators. Some of the key components in this system that keep it operating at peak performance include the starter, voltage regulators, alternator, and battery.

The alternator plays a big role in the vehicle’s charging system. Your battery requires approximately a 12-volt charge to start the vehicle and aid in running the various accessories. Without a constant slow charge, the battery would likely die within minutes. The alternator prevents this by delivering 13.5 to 14.5 volts to the electrical system while the engine runs. This allows the various electrical components to operate while the battery uses the excess voltage to recharge.

Because the alternator plays a crucial role in your starting and charging system, immediately replacing a weak or failed alternator is essential. But not all alternators are equal. You’ll want to ensure it lasts a long time by purchasing a high-quality replacement part.
