Abstract
A vehicle may include a vehicle charging system having an alternator operatively coupled to an engine and a controller. The controller may be programmed to output a warning indicative of a vehicle charging system fault in response to a quotient of a voltage drop associated with the alternator and an output current of the alternator exceeding a threshold value while the alternator is operating in a steady state condition.
