## Discrepancy

DURING EMERGENCY LIGHT PREFLIGHT CHECK THE FORWARD OVER WING LIGHT, SEAT 8 LIGHT, AND AFT WALL EXIT SIGN LIGHT DID NOT ILLUMINATE. WE POWERED UP THE AIRPLANE TO DO THE REST OF THE PREFLIGHT CHECKS AND ALL EMERGENCY LIGHTS ILLUMINATED EXCEPT THE AFT WALL EXIT SIGN LIGHT. CORRECTIVE ACTION: GAINED ACCESS TO AFT PARTITION EXIT SIGN AND FOUND POWER WIRE DISCONNECTED FROM SPLICE. RECONNECTED POWER WIRE TO SPLICE AS REQUIRED. PERFORMED SATISFACTORY OPERATIONAL CHECK WITH NO DEFECTS. ALL WORK PERFORMED IN REF WITH CE-680 AMM 33-55-10. GAINED ACCESS TO A/C AND APPLIED EXTERNAL GPU POWER. AFTER PERFORMING REQUESTED BATTERY EXCERCISE PROCEDURE FOUND JUST THE AFT LH PARTITION EXIT SIGN IS STILL INOP. PROCEEDED TO GAIN ACCESS TO AFT PARTITION EXIT SIGN AND FOUND POWER WIRE DISCONNECTED FROM SPLICE. RECONNECTED POWER WIRE TO SPLICE AS REQUIRED. PERFORMED SATISFACTORY OPERATIONAL CHECK WITH NO DEFECTS. CLOSED OUT ALL GAINED ACCESS AND RETURNED AIRCRAFT BACK TO ORIGINAL CONFIGURATION. ALL WORK PERFORMED IN REF WITH CE-680 AMM 33-55-10.
