If your vehicle’s electrical system is suddenly showing symptoms of trouble, the lights dimming with the use of the rear defroster or air conditioning, or the power windows moving very slowly, the source of these issues may well be your BMW 318I alternator. Using a belt and pulley to draw mechanical energy directly from the engine, the BMW 318I alternator converts this energy into electricity to keep your battery fully charged, supplying the power needed by the many electrically powered vehicle components and accessories. Without the function of the BMW 318I alternator, the battery in your vehicle would be quickly drained by the heavy demand of the electrical system.

The BMW 318I alternator is composed of three separate charging units, each producing its own supply of electricity in turn, allowing it to produce its voltage even when the vehicle is idling, unlike the older systems that required a higher engine speed to charge the vehicle battery effectively. These independently operating sections also offer the advantage of a little warning when your BMW 318I alternator is on its way out, often failing one section at a time, leaving a reduced level of power production in place rather than failing suddenly and completely, leaving you stranded with a vehicle that cannot start or run.
