A. If the test confirms the fault:
- do a check of the status of the circuit breaker (1PX).
(1) If the circuit breaker is closed:
- do a check for 28VDC on the pin 6 of the module 14PN (Ref. ASM 24-43/01).
(a) If there is no 28VDC:
- do a check of the wiring between the circuit breaker (1PX) and the DC SVCE BUS ground supply contactor (Ref. ASM 24-43/01).
1 If there is no continuity:
_ - repair the wiring.
2 If there is continuity:
_
- replace the C/B-SVCE 601PP/602PP SPLY (1PX).
(b) If there is 28VDC:
- do a check for 28VDC on the pin 3 of the DC SVCE BUS ground supply contactor (Ref. ASM 24-43/01).
1 If there is no 28VDC:
_
- do a check of the wiring between the pin 6 of the module 14PN and the pin 5 of the contactor (Ref. ASM 24-43/01).
a If there is no continuity:
_ - repair the wiring.
b If there is continuity:
_
- replace the C/B-ELEC/DC SVCE/BUS/ON TR2 (5PX) or the CNTOR-DC SVCE BUS GND SPLY (3PX) (Ref. AMM TASK 24-43-55-000-001) and (Ref. AMM TASK 24-43-55-400-001).
2 If there is 28VDC:
_
- replace the CNTOR-DC SVCE BUS GND SPLY (3PX) (Ref. AMM TASK 24-43-55-000-001) and (Ref. AMM TASK 24-43-55-400-001).
(2) If the circuit breaker is open:
- close it.
(a) If the circuit breaker trips:
- do a check for short to ground of the wiring between the circuit breaker (1PX) and the busbars (601PP) and (602PP) (Ref. ASM 24-43/01).
