## Discrepancy

CABIN DOOR OPEN AMBER CAS: AMBER CABIN DOOR OPEN CAS MESSAGE WILL NOT EXTINGUISH WITH DOOR CLOSED. AMBER DOOR OPEN LIGHT WILL MOT EXTINGUISH WITH DOOR HANDLE DOWN. NO AUDIBLE CLICK WHEN CABIN DOOR CLOSED. CONFIRMED SQUAWK AND FOUND THAT THE HANDLE LOCKING PAWL WILL NOT ACTUATE WHEN DOOR CLOSES. INSPECTED WIRING FOR ANY VISIBLE SIGNS OF DAMAGE.  NO DAMAGE WAS FOUND.  CHECK WIRE CONTINUITY OF THE PAWL SOLENOID AND HANDLE UNLOCK SWITCH.  CONTINUITY CHECKS GOOD.  FOUND PAWL SOLENOID IS NOT RECEIVING POWER FROM PCB NC105 TO ACTUATE IT CLOSE. ALL WORK IAW WDM 52-10-01-01 & MM 52-70-00.   UPON FURTHER RESEARCH AND TROUBLESHOOTING PERFORMED THE RESET PROCEDURE IAW AFM 3-510-28.  OPS CHECK GOOD IAW 52-70-00.
