-------------------------------------------------| SIGNAL LINE | CONNECTOR 10QG-B | |-----------------------------|-------------------| | MOTOR 2 CLOSE 28VDC SUPPLY | C | | MOTOR 2 GROUND/EARTH | E | -------------------------------------------------
NOTE : If the ground/earth is missing from the pin E, of
____ connector 10QG-B, motor 2 of the actuator would not operate. In such a case the valve would move slowly in both directions powered by motor 1 only.
(5) If the supplies are:
(a) Correct as given in the tables above:
1 Replace the ACTUATOR-LP FUEL VALVE, ENG 2 (10QG), (Ref. AMM
_ TASK 28-24-51-000-001), and (Ref. AMM TASK 28-24-51-400-001).
2 If the fault continues:
_
- replace the VALVE-LP FUEL, ENG 2 (13QM), (Ref. AMM TASK 28-24-41-000-001), and (Ref. AMM TASK 28-24-41-400-001).
(b) Not correct as given in the tables above:
- do a check of the RELAY-ENG/MASTER 2 (12QG) 103VU126 and replace if necessary.
(6) Do the test given in Para. 3.A.

(7) If the fault continues do a wiring check (Ref. AWM 28-24-02) of the:
- aircraft wiring (motor 1 close supply) between the RELAY-ENG/MASTER 2 (12QG), terminal A1, and the electrical supply connector 10QG-A, pin C
- aircraft wiring (motor 2 close supply) between the RELAY-ENG/MASTER 2 (12QG), terminal B1, and the electrical supply connector 10QG-B, pin C.
(8) Repair all the unserviceable wiring and connectors.
(9) Do the test given in Para. 3.A.
