1. A method for identifying an electrical fault in a generator that includes a regulator and a rectifier having rectifier elements, the method comprising:

  • ascertaining at least one parameter indicating a proportion of time during which a current is flowing through at least one of the rectifier elements; and

    determining that an electrical fault exists if the at least one parameter deviates by more than a predetermined amount from an expected value, wherein the expected value is derived from a characteristic curve that indicates values for the at least one parameter as a function of excitation current values of an excitation winding of the generator, the parameter values indicating those of a faultless generator.
