Wires within the alternator cut through a magnetic field to induce electrical current that is used to power your car's accessories. A performance Silverado alternator outputs between 13.5 and 14.8 volts, the voltage needed to keep you battery fully charged and run all of your vehicle's electrical systems at the same time. Alternators play a crucial role in how your car runs and performs. AutoZone's trustworthy staff are always available to help you find the alternator your vehicle needs.
