Aug 01/05 CES (b) If the circuit breaker (23XS) is closed:
- do a check and repair the wiring between the circuit breaker APU GEN/EGIU2/115VAC (23XS) and the pin AB/1D of the EGIU2 (22XU2) (Ref. ASM 24-23/01).
1 If the fault continues:
_
- do a check and repair the wiring between the circuit breaker APU GEN/EGIU2/115VAC (23XS) and the pin A/D of the APU GLC (3XS) (Ref. ASM 24-23/01).
(2) If the fault continues:
- do a check and repair the wiring (Ref. ASM 31-54/03) between: . the pin B/13A of the EGIU2 (22XU2) and the pin B/10J of the SDAC1 (1WV1) . the pin B/13B of the EGIU2 (22XU2) and the pin B/10K of the SDAC1 (1WV1) . the pin B/13C of the EGIU2 (22XU2) and the pin B/10J of the SDAC2 (1WV2) . the pin B/13D of the EGIU2 (22XU2) and the pin B/10K of the SDAC2 (1WV2)
D. If the test confirms the fault:
- replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
(1) If the fault continues:
- do a check of the wiring between: . the pin A/2B of the APU GCU (1XS) and the pin B/9D of the EGIU2 (22XU2), . the pin A/2C of the APU GCU (1XS) and the pin B/9C of the EGIU2 (22XU2). Then make sure that the ground wire is correctly connected to the pin B/10D of the EGIU2 (22XU2) (Ref. ASM 24-23/02).
(2) If the fault continues:
- replace the GCU-APU (1XS) (Ref. AMM TASK 24-23-34-000-001) and (Ref. AMM TASK 24-23-34-400-001).
(3) If the fault continues:
- do a check and repair the wiring (Ref. ASM 31-54/03) between: . the pin B/13A of the EGIU2 (22XU2) and the pin B/10J of the SDAC1 (1WV1) . the pin B/13B of the EGIU2 (22XU2) and the pin B/10K of the SDAC1 (1WV1) . the pin B/13C of the EGIU2 (22XU2) and the pin B/10J of the SDAC2 (1WV2) . the pin B/13D of the EGIU2 (22XU2) and the pin B/10K of the SDAC2 (1WV2)
