[QUOTE="SicAudio, post: 7187247, member: 609136"] also... In the case of modern automotive alternators the voltage regulator "regulates" the output from the alternator by limiting the current flowing through the rotating field assembly inside the alternator. The weaker the electromagnetic field of this "rotor" the lower the output (both current and voltage) of the alternator. When the electrical load on the alternator is low the regulator reduces the field strength [B]based on it's set upper voltage limit[/B]. When the load increases beyond the capacity of the "limited" output the voltage drops (the load is kind of "shorting out" the power from the alternator) and the regulator allows the field current (and therefor the output of the alternator) to rise until the voltage reaches that "upper limit" again and so on. automotive alternators/regulators do not have a "low limit" go pull some specs from denso or nippon they publish them online none of them have a low voltage cutoff ect... as you refer too....
