B. If the test confirms the fault:
- do a check of the status of the circuit breaker (2PU2).
(1) If this circuit breaker is closed:
- replace the CNTOR-TR 2/AC SVCE BUS NORM SPLY (14PU) (Ref. AMM TASK 24-32-55-000-001) and (Ref. AMM TASK 24-32-55-400-001).
(a) If the fault continues:
- replace the RELAY-GND/FLT SELECT CTL (7XX).
(b) If the fault continues:
- replace the CNTOR-AC & DC GND SVCE SPLY (14XX).
(c) If the fault continues:
- do a check and repair the wiring between respectively: . the circuit breaker (3XX) and the pin B/3 of the TR2/AC SVCE BUS normal supply contactor (14PU) . the pin B/5 of the contactor (14PU) and the ground (Ref. ASM 24-32/01) and (Ref. ASM 24-42/01).

- close it.
(a) If it trips:
- do a check of the wiring for a short to ground between respectively the pins A/2, B/2, C/2 of the circuit breaker (2PU2) and the pins A/D, A/E, A/F of the TR2/AC SVCE BUS normal supply contactor (14PU) (Ref. ASM 24-32/01).
