Nissan Altima Alternators & Parts

The alternator is one of the major parts of the starting and charging system of your Nissan Altima. The main function of the alternator is to convert mechanical energy into electrical one, which your engine requires to start and operate properly. Typically, the alternator features a two-piece housing made from aluminum and includes a stator, rotor, rectifier assembly, voltage regulator, and a pulley, which receives mechanical energy from the engine crankshaft. The stator is a stationary set of electric windings. The drive belt has to spin the rotor inside the stator, thus generating magnetic field and creating electric energy.

Typically, there are two bearings inside, which are needed for rotor's rotation. The bearings and voltage regulator are those parts which ask for replacement most often. The bearings just become noisy over the years, but other malfunctions can light the Battery indicator on your dash panel, which means that the alternator doesn't charge the battery. If so, have it inspected at the service station as soon as possible. Here you can browse an array of first-rate Nissan Altima replacement alternators and their components made by reputable companies.
