The test required is as follows:
(a) Continuity test, with a multimeter, of each three phase wire (from end to end) (Ref. ESPM 20-52-21).
(b) Insulation test, with a 500VDC insulation tester, between each phase wire (pole) and ground (Ref. ESPM 20-52-24).
(c) Insulation test, with a 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.
CAUTION : DO NOT USE IN-LINE SPLICES TO REPAIR SECTIONS OF ELECTRICAL
_______ CABLE THAT ARE BEHIND A FAIRING OR IN A CONDUIT. THIS WILL MAKE SURE THAT IT IS POSSIBLE TO SEE THE REPAIR FOR AN INSPECTION (REF. ESPM 20-53-29).
(a) If the fuel pump supply cable between the connector 21QA-A(22QA-A) and the related junction box (bracket assembly) on the rear spar is seen to be damaged, repair as follows:
1 If necessary, replace the unserviceable:
_
- protective sleeve
- wire(s)
- connector.
2 Connect the new wire(s) of the fuel pump supply cable where
_ the wiring passes through the junction box (bracket assembly), by a splice(s) (Ref. ESPM 20-53-21).
3 Make sure that the length of the new supply cable when
_ assembled, between the front face of the connector 21QA-A(22QA-A) and the forward face of the cable guide (that shows outside the wing-skin) is:
- 1345 mm (52.95 in) for the left (outer) wing tank pump No. 1
- 21QA
- (1320 mm (51.97 in) for the right (inner) wing tank pump No. 1 - 22QA).
4 If necessary, make any final adjustment in the length of the
_ supply cable across the lower surface of the wing during the installation of the rear fairing.
5 Feed the surplus cable (small amount only) into the flexible
_ conduit to the junction box (bracket assembly) on the rear spar.
6 Make sure that the supply cable is held tight by the P-clip at
_
the cable guide.

NOTE : It is important that the fuel pump supply cable is
____ installed correctly as given in steps 2_ thru 6_. Incorrect installation of the cable can cause it to get damaged. If the cable is too short it will put tension on the wires and plug. If the cable is too long you will not be able to install the fairings correctly. This is because the unwanted cable (excess length) will become looped and get trapped during the installation of the intermediate and rear fairings.
(17) The fuel pump supply cable end connector 21QA-A(22QA-A) must stay disconnected.
(18) Install the fuel pump, rear and intermediate, fairings (Ref. AMM TASK 28-21-49-400-001): Make sure that the fuel pump supply cable:
- is held correctly by the tape hooks (post SB 24-1070)
- does not get caught under the fairings (this is very important in the area adjacent to the fairing attachment bolts).
(19) Do a wiring test, as detailed in the step (15), of the aircraft wiring (three phase electrical supply) (Ref. ASM 28-21/01) between the CNTOR-L(R) WING TK PUMP 1 SPLY 17QA(18QA) and the PUMP-FUEL No. 1, L(R) WING TK connector 21QA-A(22QA-A).
(a) If the wiring test:
1 Is serviceable, do step (20).
_
2 Is unserviceable, do steps (15) thru (19) again.
_
(20) Connect the fuel pump supply cable end connector 21QA-A(22QA-A) to the fuel pump receptacle.
(21) Close (reset) the C/B-1QA(2QA).
(22) Do the Operational Test of the Wing-Tanks Fuel Control (Ref. AMM TASK 28-21-00-710-001).

A. Procedure
NOTE : This procedure is written for the C/B-FUEL/L WING TK/PUMP 1 SPLY
____ 1QA with the C/B-FUEL/R WING TK/PUMP 1 SPLY 2QA given in parenthesis, if different.
(1) Do all the steps (2) thru (20) before you close the C/B-FUEL/L(R) WING TK/PUMP 1 SPLY 1QA(2QA) in step (21).
