4 Do a check to see if 28VDC is available between the pins as
_
shown in the table that follows.
-------------------------------------------------| SIGNAL LINE | CONNECTOR 10QG-A | |-----------------------------|-------------------| | MOTOR 1 OPEN 28VDC SUPPLY | A | | MOTOR 1 GROUND/EARTH | E | -------------------------------------------------
5 Reconnect the electrical supply connector 10QG-A to the
_ ACTUATOR-LP FUEL VALVE, ENG 2 (10QG).
(b) Disconnect the electrical supply connector 10QG-B from the ACTUATOR-LP FUEL VALVE, ENG 2 (10QG).
1 Do a wiring check (Ref. AWM 28-24-02) of the aircraft wiring
_ (motor 2/ground/earth) between the ACTUATOR-LP FUEL VALVE, ENG 2 free connector 10QG-B, pin E and the ground/earth point 4004VN(622STA450) to make sure a ground/earth is on pin E of connector 10QG-B.
2 Set the ENG/MASTER 2 (2KC) switch to OFF.
_
3 Do a check to see if 28VDC is available between the pins as
_
shown in the table that follows.
-------------------------------------------------| SIGNAL LINE | CONNECTOR 10QG-B | |-----------------------------|-------------------| | MOTOR 2 CLOSE 28VDC SUPPLY | C | | MOTOR 2 GROUND/EARTH | E | -------------------------------------------------
4 Set the ENG/MASTER 2 (2KC) switch to ON.
