(10) If the 28VDC is not available between pin E and pin D of the end connector 6QT-A:
(a) Do a check of and replace, if necessary, the RELAY-REFUEL/DEFUEL CTL PNL DOOR POSITION (14QU).
(b) Do a check of the aircraft wiring (28VDC supply) (Ref. ASM 28-42/03) between:
- the end connector 6QT-A, pin E and the RELAY-REFUEL/DEFUEL CTL PNL DOOR POSITION (14QU), terminal B1
- the RELAY-REFUEL/DEFUEL CTL PNL DOOR POSITION (14QU), terminal B2 and the C/B-FUEL/FQI/CHANNEL/1 and 2 (8QT).
(c) Do a check of the aircraft wiring (ground supply) (Ref. ASM 28-42/03) between the end connector 6QT-A, pin D and the ground point.
(d) Repair all the unserviceable wiring and connectors.
(e) Do the test given in Para. 3.B.
(11) If the fault continues:
(a) Do a check of the aircraft wiring ARINC 429 BUS electrical wires (Ref. ASM 28-42/03) between:
- the FQICC (3QT) rack connector AB, pin 12A and the indicator end connector 6QT-A, pin B
- the FQICC (3QT) rack connector AB, pin 13A and the indicator end connector 6QT-A, pin C.
(b) Repair all the unserviceable wiring and connectors.
(c) Do the tests given in Para. 3.B.
**ON A/C 301-399,
A. Procedure - The Indicator LEDs Do Not Come On At Indicator Power-up OR The Message INDICATOR 6QT Is Shown On The FQIS STATUS Page
(1) Examine the LEDs on the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT).
(a) If the LEDs on the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT) are on, go to step (7).
NOTE : This shows the C/B-8QT is closed, the RL-14QU energized
____
and 28VDC available.

(b) If the LEDs on the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT) are off, go to step (2).
NOTE : This shows the C/B-8QT is open, or a common 28VDC power
____ supply failure.
(2) On the MCDU go to SYSTEM REPORT/TEST - FUEL (Ref. AMM TASK 31-32-00-860-001).
(3) Do the Interrogation of the FQIS Input Parameter Pages (Ref. AMM TASK 28-42-00-740-003).
(4) Go to the Input Parameters Page 3 - FQIS DISCRETE INPUTS.
(5) Examine the bit 2D (28VDC FUELLING BUS 2, ON).
(a) If bit 2D shows a 1 (is on), go to step (6).
(b) If bit 2D shows a 0 (is off):
(6) Examine the bit 2M (TX FAULT/INDICATOR NOT POWERED).
(a) If the bit 2M shows a 0 (is on/no TX fault), replace the IND-FUEL QTY MULTI TANK (6QT) (Ref. AMM TASK 28-42-22-000-001) and (Ref. AMM TASK 28-42-22-400-001).
(b) If the bit 2M shows a 1 (is off/TX fault), go to step (7).
(7) Remove the indicator (6QT) (Ref. AMM TASK 28-42-22-000-001).
(8) Use a multimeter to do a test, at the indicator end connector 6QT-A, to make sure that the 28VDC is available between pin E (+ve) and pin D (-ve).
(9) If the 28VDC is available between pin E and pin D of the end connector 6QT-A, replace the IND-FUEL QTY MULTI TANK (6QT) (Ref. AMM TASK 28-42-22-000-001) and (Ref. AMM TASK 28-42-22-400-001).
1_ Do a check of and close or replace (if necessary) the
C/B-FUEL/FQI/CHANNEL/1 AND 2 (8QT).
2_ Do a check of the aircraft wiring (28VDC FUELLING BUS 2
electrical wire) between the C/B-FUEL/FQI/CHANNEL/1 AND 2
(8QT) and the FQIC (3QT) rack connector AB, pin 9D (Ref. ASM
28-42/03).
3_ Repair all the unserviceable wiring and connectors.
4_ Do the tests in Para. 3.B.
