## Discrepancy

LOST GND POWER AT GATE.  TURNED ON EMER LIGHTS TO ARMED, GOT LIGHTS ONLY AT EMER EXIT AISLE SEATS.  TURNED SWITCH TO ON, ONLY LIGHTS AT EMER EXIT AISLE SEATS.  FOUND FWD, AFT & LT POWER SUPPLIES NOT POWERING EMER LIGHTS WITH POWER OFF.  REPLACED FWD & AFT POWER SUPPLIES & FWD AFT & LT BATTERIES.  CHECKED GOOD.
