__________________
A. Test
Not applicable.
NOTE : As the GEN 2 was set to OFF because of a true failure, the fault
____
confirmation is not necessary.
4. Fault Isolation
_______________
A. If the fault symptom is identified by the CFDS message WRG: GEN2 FEEDER PHASE C/ IDG2 (E2-4000XU) and the upper ECAM-DU warning GEN 2 FAULT:
- do a check of the resistance of the main stator windings of the IDG 2 (Ref. ASM 24-22/01) between terminals T3 and N (7 milliohms plus or minus 1 milliohm).

(1) If the resistance values are out of the specified limits:
- replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
(2) If the resistance values are in the specified limits:
- do a check of the feeder (Ref. ASM 24-22/01) for an open circuit condition or a high resistance between terminal T3 of the IDG 2 and terminal F of the GLC 2.
(a) If the feeder is not correct:
- repair or replace the feeder as necessary.
(b) If the feeder is correct:
- replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
1 If the fault continues:
_
- replace the engine 2 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
