An alternator replacement is a physical action on an engine component, removing it and putting in a new or reconditioned unit to take its place and perform its function. The alternator is the belt-driven unit that charges the 12-volt battery as the engine runs. If you’re having trouble starting your car, you may need an alternator replacement. A malfunctioning alternator can cause underperforming lights, instruments, accessories, and a dead battery.

An electric vehicle (EV) generally doesn’t have an alternator, as all power comes from its rechargeable battery pack.
