Where Is the Alternator Located?  

Your car’s alternator generates the electricity required to charge the battery and run all the electrical components of the vehicle. Your alternator will be mounted towards the front of the engine, and you’ll see the front of the alternator with its pulley connected to a long belt called a serpentine belt. The alternator will be mostly grey or silver with lots of holes in its housing to allow air through for cooling, and if you look closely, you can usually see the copper windings of the stator or rotor inside the housing. The stator is the set of copper windings that stay in one place, while the rotor is the set of copper windings that rotates on a shaft in the middle of the alternator. The pulley that attaches to the serpentine belt is connected to the rotor with that shaft.
