## Discrepancy

EMERGENCY FLOOR LIGHTS INOP AT SEATS 1, 2, 8, 9 & 10.  SEAT 10 WAS INOP; REPAIRED CONNECTOR.  NOW 10 WORKS OK.  REF WDM 33- 51-06 POST SB 33-1041 WIRE MOD TO EMERG LIGHT CIRCUITS, WORKING WITH SAMC TO FIND BASE COA FOR PWR TO THESE SEATS OR LOCATION OF BATTERY 110WT1 FROM POST COA.  RECEIVED POST COA AND FOUND SHORTING FLOOR LIGHTS, REPAIRED BY SEAT 6 PER SWPM AND REPLACED EPSU.  ALL LIGHTS WORK NORMAL.
