R (a) If the resistance is less than 280 ohms:
R - install a new F/O W ANN SPLY relay (42CE2) (Ref. IPC 27920803)
R - replace the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-000-001)
R (Ref. AMM TASK 27-95-34-400-001).
R (b) If the resistance is more than 400 ohms
R - install a new F/O W ANN SPLY relay (42CE2) (Ref. IPC 27920803)
R - see Para. (3).
R (c) If the resistance is between 280 and 400 ohms:
R - install the F/O W ANN SPLY relay (42CE2)
R - See Para. (3).
R (3) If the fault continues:
R (a) Replace the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-000-001) (Ref.
R AMM TASK 27-95-34-400-001).
R (4) If the fault continues:
R (a) Replace the RELAY-F/O W ANN SPLY (42CE2) (Ref. IPC 27920803).
R (5) If the fault continues:
R (a) Do a check of the wiring between the F/O W ANN SPLY relay (42CE2)
R pin X2 and the FCDC-1 (3CE1) (Ref. ASM 27-95/04).
R (b) Do a check of the wiring between the F/O W ANN SPLY relay (42CE2)
R pin A1 and the ground.
R (c) Do a check of the wiring between the F/O W ANN SPLY relay (42CE2)
R pin X1 and the first terminal block.
R B. If, during the test, with circuit breaker 20CE2 opened (circuit breaker
R 20CE1 closed):
R - the CAPT legend of the SIDE STICK PRIORITY annunciator does not come on
R when you move the F/O side stick:
R (1) Replace the FCDC-1 (3CE1) (Ref. AMM TASK 27-95-34-000-001) (Ref. AMM
R TASK 27-95-34-400-001).
R (2) If the fault continues:
R (a) Replace the BOARD-ANN LT TEST & INTFC (2LP) (Ref. IPC 33140803).
R (3) If the fault continues:
R (a) Replace the RELAY-CAPT G ANN SPLY (42CE3) (Ref. IPC 27920803).
