## Discrepancy

BATTERY WAS LEFT ON.  UPON RETURN TO ACFT 2 HOURS LATER, BATTERY WAS TOO LOW TO START ACFT.  PILOT THOUGHT BATTERY/EPU SWITCH WAS TURNED OFF, BUT YOU HAVE TO PUSH THE BUTTON UP TO 4 TIMES BEFORE IT STAYS IN SELECTED POSITION.  CONFIRMED PILOT`S SNAG.  BATTERY/EPU SWITCH STICKY/STIFF/INTERMITTENT.  REPLACEMENT PART ORDERED.
