ABSTRACT:
A vehicular alternator failure determination apparatus is capable of making a failure determination accurately. The apparatus includes a maximum voltage detection part (1) for detecting a maximum voltage of an alternator commutating device which commutates an AC output of the alternator driven by an engine, a minimum voltage detection part (2) for detecting a minimum voltage of the alternator commutating device, a voltage difference calculation part (3) for detecting a difference voltage from outputs of the maximum and minimum voltage detection parts, and a failure determination part (4) which determines that the alternator is in a failure state, when an output of the voltage difference calculation part is equal to or greater than a prescribed voltage.
