Abstract: A system and method regulates an alternator charging system and includes a memory for storing and regulating voltages used at specific temperatures for the specific alternator charging system requirements of an alternator. A circuit generates a digital signal indicative of both temperature of a battery supplied by the alternator charging system and the charging system voltage. A digital comparator receives the digital signal and compares the digital signal with the regulating voltage stored within the memory for the specific temperature that is indicative of the temperature of the battery supplied by the alternator charging system to generate a regulator control signal.
