## Discrepancy

(CAN) ON MARCH 27, 2000, PILOT REPORTED ON CLIMB-OUT, ENGINE SUDDENLY RAN ROUGH AND COMPLETE ELECTRICAL FAILURE FOR 5 SECONDS.  CHECKED ALL WIRING AND ENGINE FOR ANY ABNORMAL SIGNS.  NONE FOUND.  RAN FINE ON GROUND, ETC.  OPENED IGNITION SWITCH AND FOUND A LITTLE DIRTY (BUT DRY).  CLEANED CONTACT PLATES AND LUBRICATED WITH ELECTRICAL LUBE AND RE-ASSEMBLED.  PERFORMED TEST FLIGHT AND FOUND NOT EVEN A STUTTER.  AIRCRAFT WAS FLOWN 150 HRS SINCE THEN WITH NO DIFFICULTY.   NOTE:  SUBMITTER NOT POSITIVE THAT THE IGNITION SWITCH CAUSED THIS.  COULD BE SOMETHING ELSE AND DID NOT THINK THE SWITCH WAS THAT BAD BUT COULD NOT FIND ANYTHING ELSE.
