Analysis

About 30 min after departure, electrical equipment began to fail. The plt turned off the alternator & reset with no change. He then switched to the #1 regulator which did not correct the problem. While turning on downwind the gear handle was placed down & all elect power was lost. The plt then cranked the gear down until resistance was met, but did not count the number of revolutions. The acft touched down with partially extended landing gear. Both batteries were found dry. The left alternator had no output & right alternator current limiter was burned open. The plt indicated during a subsequent interview that he did not turn off any electrical equipment. He also stated that he had not exercised the emerg landing gear system in flight prior to this mishap.
