(5) If the fault continues:
- do a check for 115 VAC at the pins B,C,D and E,F,G, and I,J,K at the related GALLEYS.
(a) If there is no 115 VAC :
- do a check of the related GALLEY PWR RELAY and replace it if necessary.
(6) If the fault continues:
- do a check and repair the wiring between the related: GALLEY pins B,C,D or E,F,G or I,J,K and the related CB, GALLEY pins A or H or L and the related GND (Ref. ASM 24-56/01).
B. If the white indicator light FAULT in PBSW 2XA does not come on, but there is a fault in the galley equipment:
- do a check of the PBSW 2XA and replace it if necessary.
(1) If the fault continues:
- do a check and repair the wiring between: CB 1XA and PBSW 2XA connector A/C3 (Ref. ASM 24-56/01).
C. Do the test as given in Para. 3.A. to check the correct operation (no maintenance message is shown).

4. Fault Isolation
_______________
A. If the test confirms the fault:
- replace the 8PH (Ref. AMM TASK 24-62-55-000-001) and (Ref. AMM TASK 24-62-55-400-001).
(1) If the fault continues:
- do a check and repair the wiring between: . the pin B/21 of the contactor (8PH) and the first branch point . the pin B/19 of the contactor (8PH) and the ground (Ref. ASM 24-62/01).
B. Do this test to make sure that the system operates correctly:
