ABSTRACT:
A microcomputer implemented apparatus and method for detecting the occurrence of a shorted diode in the rotating rectifier of a brushless alternator. The alternator current, voltage and power output and the alternator temperature are measured. The anticipated exciter field current is determined for the alternator output and operating conditions and compared with the actual exciter field current. An actual exciter field current in excess of the anticipated current indicates a rectifier fault.
