The GMC Sonoma's Alternator is another part that is an in-house charger for the car battery and charges it when the car is in motion and specs other electrical parts. Sitting ahead of the engine, the alternator shifts mechanical energy arising from the engine operation into electrical energy that is supplied to the various components such as the battery. In the same manner that a DC generator, the alternating current is produced by a rotating magnetic field while the armature is stationary and the battery is recharged together with the rest of the automobile's electrical systems. Due to the fact that the alternator regulates voltage output to avoid situation where it charges less than it should or charges more than it should, the component is crucial in managing the electric operations of the car. Also, the high output alternators for those vehicles with high electrical carrying capacity as well as for modified vehicles or those equipped with extra parts are also available.
