4. Fault Isolation
_______________
R A. If the test confirms the fault: On the upper ECAM display unit:
- these warnings come into view:ELEC AC BUS 1 FAULT ELEC AC ESS BUS FAULT ELEC DC ESS BUS FAULT

On the overhead panel, on panel 35VU:

- the FAULT legend of the AC ESS FEED pushbutton switch is on.

R - do a check of the feeders between the GLC1 (9XU1) and the busbar 1XP
R (Ref. AWM 24-51-05), (Ref. AWM 24-51-07) and (Ref. AWM 24-51-09).
R (1) If the feeders are not correct:
R - repair them.
R (2) If the feeders are correct:
R - do a check of the feeders between the GLC1 (9XU1) and the IDG1
R (4000XU) for a short to ground or a short circuit (Ref. AWM 24-22-
R 01).
R (a) If the feeders are not correct:
R - repair them.
R (b) If the feeders are correct:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-
