__________________
A. Test
(1) Do the Operational Test of the Generator Line Contactor (GLC-1) Opening in the Smoke Procedure (Ref. AMM TASK 24-22-00-710-001).
(2) If a low fuel pressure indiction is shown when the right wing tank fuel pump No. 1 is supplied from:
(a) The normal supply (AC BUS 1 and through the contactor-18QA), do (Ref. TASK 28-21-00-810-802) and (Ref. TASK 28-21-00-810-808).
(b) The standby supply (direct from the Generator No. 1 and through the contactor-54QA), do Para. 4.A.
4. Fault Isolation
_______________
A. Procedure
(1) Do a check of (Ref. ASM 28-21/01) and replace, if necessary:
- the C/B-R WING TK/PUMP 1/STBY SPLY (12QA)
- the CT-AC, 1 (42XU3) (Ref. AMM TASK 24-22-17-000-001) and (Ref. AMM TASK 24-22-17-400-001).
- the CNTOR-R WING TK STBY SPLY, PUMP 1 (54QA).
(2) Do a check, with a multimeter, of the aircraft wiring (three phase electrical standby supply) (Ref. ASM 24-22/02) and (Ref. ASM 28-21/01) between:
- the contactor GLC-1 (9XU1) (Gen 1 connected terminals D, E and F) and the C/B-R WING TK/PUMP 1/STBY SPLY (12QA)
NOTE : Each phase of the wiring between these two units goes through
____ a different toroidal transformer of the CT-AC, 1 (42XU3). There is no direct electrical connection.
- the C/B-R WING TK/PUMP 1/STBY SPLY (12QA) and the CNTOR-R WING TK STBY SPLY, PUMP 1 (54QA)
- CNTOR-R WING TK STBY SPLY, PUMP 1 (54QA) and the PUMP-FUEL No. 1, R WING TK free connector 22QA-A.
(3) Repair the unserviceable wiring and connectors.
(4) Do the test given in Para. 3.A.
