Updated for 2009! This video provides an overview of the charging system, with its battery, alternator, voltage regulator, and starter solenoid; a detailed examination of the alternator and its construction; a close-up look at the function of the alternator's rectifier; and a comparison of the internal voltage-type voltage regulator with its predecessors, the remote solid state and contact point voltage regulators.
