(8) If the REFUELG memo message is not shown:
- install the initial FQIC (3QT) (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001)
(9) Do a check of the aircraft wiring (Ref. ASM 28-42/03) between:
- the C/B-FUEL/FQI/CHANNEL/1 AND 2 (8QT) and the FQIC rack connector AB, pin 9D (refuel bus powered input supply wire to the FQIC).

A. Procedure
(1) Make sure that the REFUEL panel door is open.
(2) At the CTL PNL-REFUEL/DEFUEL (800VU), do the steps that follow to check the availability of the different 28VDC refueling supplies:
(a) 28VDC Refueling Bus 1 501PP
1 C/B-1QJ output
_ Do the HI LVL LTS TEST (Ref. AMM TASK 12-11-28-650-003) to see if they come on/illuminate.

Nov 01/04R CES
2 C/B-2QU output
_ Monitor the FLOODLIGHT-REFUEL/DEFUEL CTL PNL (32QU) to see if it is on/illuminated.
(b) 28VDC Refueling Bus 2 502PP
1 C/B-8QT
_ Monitor the displays of the PRESELECTOR-FUEL QUANTITY, MULTI TANK (5QT) and the IND-FUEL QTY MULTI TANK (6QT) to see if they come on/are energized.
(3) If all three of the checks in step (2) operate or illuminate correctly, go to step (6).
(4) If one of the checks in step (2) does not operate or illuminate correctly, go to P. Block 101 and do the applicable troubleshooting.
(5) If all three of the checks in step (2) do not operate or illuminate correctly, do Refueling not Possible (Ref. TASK 24-67-00-810-801).
(6) Temporarily replace the FQIC (3QT) (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001).
(7) If the REFUELG memo message is shown:
- complete the installation of the FQIC (3QT) (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001).
(8) If the REFUELG memo message is not shown:
- install the initial FQIC (3QT) (Ref. AMM TASK 28-42-34-000-001) and (Ref. AMM TASK 28-42-34-400-001)
(9) Do a check of the aircraft wiring (Ref. ASM 28-42/03) between:
- the C/B-FUEL/FQI/CHANNEL/1 AND 2 (8QT) and the FQIC rack connector AC, pin 9E (refuel bus powered input supply wire to the FQIC).
