## Discrepancy

EMERGENCY PATH LIGHTING FROM ROW 32 AFT INOP. CORRECT EPL DRAWING IS BR2013-P-757CO-5 REV F. PER THE BRUCE DRAWING ROWS 32-41 ARE POWERED BY BATTERY PACK / CHARGER M736 LOCATED ABOVE THE G4 AFT GALLEY AND RECEIVES POWER THROUGH PIN 13 OF D78. ALSO, REFERENCE WDM 33-51-22-906. COULD BE A FUSE. REMOVED AND REPLACED BATTERY PACK M737 IAW AMM 33-51-07-902-001. OPS CHECKED GOOD.
