The charging system will normally consist of two major components: An Alternator which actually supplies the necessary electrical current in order to charge the battery, and a Voltage Regulator. The latter insures that the system does not overcharge the battery, and that the correct system voltage is maintained. Most vehicles produced within the last 20-30 years use a voltage regulator which is an integral part of the alternator itself. This article assumes that your vehicle uses this type of alternator.
Aside from a dead battery or faulty charging system, the most common electrical issues owners are likely to experience are burned-out light bulbs. After bulbs, though, it's likely potluck: Electrical problems could crop up in many places, from the stereo to an electric motor for a power window or sunroof to an electric fuel pump packing it in. In addition, the cause might be bad wiring, a short, there may be a faulty switch or some other gremlin that's hard to pinpoint.
