(b) Electrical Tests Do a continuity test (Ref. ESPM 20-52-21) and a test for a short circuit (Ref. ESPM 20-52-22) of the wires that follow (Ref. AWM 28-42-14) and (Ref. AWM 28-42-15):
- FQIC rack connector 3QT-A, pin 7H to connector 7509VC-A, pin H (permittivity signal)
- FQIC rack connector 3QT-A, pin 5H to connector 7509VC-A, pin W (common drive return)
- FQIC rack connector 3QT-A, pin 15G to connector 7509VC-A, pin G (common drive)
- FQIC rack connector 3QT-A, pin 6F to connector 7509VC-A, pin M (density signal)
- FQIC rack connector 3QT-A, pin 7F to connector 7509VC-A, pin Z (density signal return)
- FQIC rack connector 3QT-A, pin 9F to connector 7509VC-A, pin N (density supply/drive)
- FQIC rack connector 3QT-A, pin 10F to connector 7509VC-A, pin <A (density supply/drive return).
(c) Repair all the unserviceable wiring and connectors (Ref. ESPM 20-00-00).
(d) Connect:
- the connector 7509VC-A to the fused adaptor
- the fused adaptor to the tank wall receptacle 7509VC.
(e) Install the initial FQIC 3QT (Ref. AMM TASK 28-42-34-400-001).
(f) Do the test given in Para. 3.B.
(11) If the fault continues, drain and open the tank to the air (Ref. AMM TASK 28-10-00-910-001) and (Ref. AMM TASK 28-10-00-910-002).
(12) Do a check of the HARNESS-CHAN A, CTR TK (17QT) (Ref. AWM 28-42-14) and (Ref. AWM 28-42-15) and replace, if necessary, (Ref. AMM TASK 28-42-44-000-001) and (Ref. AMM TASK 28-42-44-400-001).
(13) If the harness 17QT is serviceable, replace the CADENSICON-CTR TK (20QT) (Ref. AMM TASK 28-42-16-000-002) and (Ref. AMM TASK 28-42-16-400-002).
NOTE : Make sure that the cadensicon transit pin is removed.
____
NOTE : If the center tank cadensicon sensor is replaced, 2000kg
____ (4400lb) of fuel must be put in the center tank before you can fully test the cadensicon.
