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).

R (4) If the fault continues:

R (a) Do a check of the wiring between the ANN LT TEST & INTFC BOARD

R pin 23 and the FCDC 1 (3CE1) (Ref. ASM 27-95/04).
R (b) Do a check of the wiring between pin 3 and pin 25 of the ANN LT
R TEST & INTFC board (2LP).

R (c) Do a check of the wiring between the ANN LT TEST & INTFC board

R (2LP) pin 4 and the first terminal block.
R (d) Do a check of the wiring between the ANN LT TEST & INTFC board
R (2LP) pin 22 and the CAPT G ANN SPLY relay (42CE3) pin A3.

R C. If during the test, with circuit breaker 20CE2 open (circuit breaker
R 20CE1 closed):

R (3) If the fault continues:
R (a) Replace the RELAY-CAPT W ANN SPLY (42CE1) (Ref. IPC 27920803).

R (4) If the fault continues:
R (a) Do a check of the wiring between the ANN LT TEST & INTFC board
R (2LP) and the FCDC 1(3CE1) (Ref. ASM 27-95/04).

R (b) Do a check of the wiring between the ANN LT TEST & INTFC board

R (2LP) pin 4 and the first terminal block.
