Cadillac DTS Alternator

Cadillac DTS Alternator is a functional part that charges the battery of the vehicle and supplies electric power to car components when the vehicle is running. Usually placed before the engine, the Alternator functions to turn mechanical energy in the form of the cranking engine into electrical energy and thereafter supply some parts like the battery. The Alternator employs the use of a rotating magnetic field and a stationary armature to produce the altering current needed to recharge the battery and supply the car's electric needs. Due to the fact that it regulates the voltage output of the battery to ensure that it does not get overcharged or undercharged, the role of an Alternator is very crucial in the running of the electrical system in any automobile.
