C130 Experts !!! We r facing a problem of generator out light on No 3 Eng for last 1 month in which AC generator, contactor, FS Relay, AC control panel alongwith Chassis, Voltage regulator is replaced but problem persists and require resetting many times to come inline. Problem mostly occurs on takeoff roll and on landing and sometimes in air. Also if we put essential bus load on No 3 Generator, it becomes offline with Vol, Freq and load zero. It gets duplicated sometime on ground as well during ground run.
