Subtask 24-56-00-710-050-A
A. Do a test of the galley supply AMM 24-56-00-710-001.
4. Fault Isolation
Subtask 24-56-00-810-050-A ** ON A/C NOT FOR ALL
A. If the white indicator light FAULT in PBSW 2XA comes on during the test:
  • do a check of the GND FAIL RELAY 4XA and replace it if necessary.
   (1) If the fault continues:
  • do a check of the GALLEY SPLY RELAY 5XA and replace it if necessary.
   (2) If the fault continues:
  • do a check of the GALLEY SPLY RELAY 9XA and replace it if necessary.
   (3) If the fault continues:
  • do a check of the MAN GALLEY SPLY RELAY 6XA and replace it if necessary.
   (4) If the fault continues:
  • do a check and repair the wiring if necessary between:
    PBSW 2XA connector A/C1 and GND FAIL RELAY 4XA connector A/A,
    GND FAIL RELAY 4XA connector A/A and GALLEY SPLY RELAY 5XA connector A/X,
    GND FAIL RELAY 4XA connector A/A and GALLEY SPLY RELAY 9XA connector A/X, (if fitted),
    GALLEY SPLY RELAY 5XA connector A/Z and GND,
    GALLEY SPLY RELAY 9XA connector A/Z and GND (if fitted),
    CB 7MC and related GALLEY PWR RELAY pin X,
    CB 7MC and related GALLEY PWR RELAY connector B/3,
    related GALLEY PWR RELAY pin Z and GND,
    related GALLEY PWR RELAY connector B/5 and GND ASM 245601.
   (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 ASM 245601.
