201-299, 401-499, Aug 01/05 CES (b) Do the test given in Para.3.B.(2).
(10) Do a test, with a multimeter, to make sure that 28VDC is available at the RELAY-R WING TK LOW LEVEL CHANNEL B (6QP) terminals A2 and X1 (Ref. ASM 28-15/01).
(a) If the 28VDC:
- is not available, do step (11)
- is available, continue at step (12).
(11) Do a wiring check of the aircraft wiring (Ref. ASM 28-15/01) between the RELAY-R WING TK LOW LEVEL CHANNEL B (6QP) and the C/B-FUEL/XFR VALVE 1/WING/R (2QP).
(a) Repair all the unserviceable wiring and connectors (Ref. ESPM 20-00-00).
(b) Do the test given in Para. 3.B.(2).
(12) If the fault continues:
(a) Do a check of and replace, if necessary, the relays that follow:
- RELAY-L WING TK LOW LEVEL CHANNEL A (5QP)
- RELAY-R WING TK LOW LEVEL CHANNEL B (6QP)
- RELAY-L OR R REAR XFR VALVE OPEN LATCH (13QP).
(b) Do the test given in Para. 3.B.(2).
(13) If the fault continues:
(a) Do a wiring check of the aircraft wiring (Ref. ASM 28-15/01) between:
- the ACTUATOR connector 11QP-A, pin A and the RELAY 5QP, terminal A3
- the ACTUATOR connector 11QP-A, pin A and the RELAY 6QP, terminal B3
- the RELAY 5QP, terminal A1 and the RELAY 6QP, terminal B2
- the RELAY 5QP, terminal X2 and the RELAY 13QP, terminal A
- the RELAY 6QP, terminal X2 and the RELAY 13QP, terminal B
- the RELAY 13QP, terminal 1 and the FLSCU-1 rack connector 7QJ-AA, pin 5A
- the RELAY 13QP, terminal 3 and the FLSCU-2 rack connector 9QJ-AA, pin 5A.
(14) Repair all the unserviceable wiring and connectors (Ref. ESPM 20-00-00).
(15) Do the test given in Para. 3.B.(2).
