(a) Continuity test, with an (intrinsically safe) multimeter, of each three phase wire (from end to end) (Ref. ESPM 20-52-21).
(b) Insulation test, with an (intrinsically safe) 500VDC insulation tester, between each phase wire (pole) and ground (Ref. ESPM 20-52-24).
(c) Insulation test, with an (intrinsically safe) 500VDC insulation tester, between each phase wire and the other two wires (pole to pole) (Ref. ESPM 20-52-24).
(16) Repair/replace the unserviceable wiring and connectors.
(a) If a wire is damaged, the complete section (length) of (each) wire (between the fuel pump connector 37QA-A (38QA-A) and the connector 7612VC-A (7577VC-A) that goes through pressure seal 7611VP (7508VP)) must be replaced (Ref. AWM 28-21-05) ((Ref. AWM 28-21-06)). This is because the wires are located in a fuel and vapour zone (Ref. ESPM 20-31-36).
(17) Install the serviceable cable on the forward and rear sides of the bulkhead at FR42.
(18) Do not connect the fuel pump supply cable end connector 37QA-A (38QA-A) to the pump receptacle.
(19) Do a wiring test, as detailed in the step (15), of the aircraft wiring (three phase electrical supply) between the connector 7612VC-A (7577VC-A) and the PUMP-FUEL No. 1 (2), CTR TK connector 37QA-A (38QA-A) (Ref. AWM 28-21-05) ((Ref. AWM 28-21-06)).
(a) If the test shows that the wiring:
1 Is serviceable, do step (20).
_
2 Is unserviceable, do steps (2) thru (19) again.
_
(20) Connect the fuel pump supply cable end connector 37QA-A (38QA-A) to the fuel pump receptacle.
(21) Close (reset) the C/B-29QA (30QA).
(22) Do the Functional Test of the Center-Tank Fuel Control (Manual Mode) (Ref. AMM TASK 28-21-00-720-001).
