R (3) Do an electrical resistance test of the IDG 1 exciter field between
R pins A/9 and A/10 (8.4 ohms plus or minus 0.84 ohm) (Ref. ASM 24-R 22/01).
R (a) If the resistance values are out of the specified limits:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-000-R 040) and (Ref. AMM TASK 24-21-51-400-040).
R (b) If the resistance values are in the specified limits:
R - do an electrical resistance test of the IDG 1 PMG stator (Ref.
R ASM 24-22/01) between:
R . pins B/12 and B/13 (1 ohm plus or minus 0.05 ohm)
R . pins B/12 and B/14 (1 ohm plus or minus 0.05 ohm)
R . pins B/13 and B/14 (1 ohm plus or minus 0.05 ohm).
R 1_ If the resistance values are out of the specified limits:
R - replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-21-51-
R 000-040) and (Ref. AMM TASK 24-21-51-400-040).
R 2_ If the resistance values are in the specified limits:
R - do a check of the wiring of the PMG stator and exciter field
R (Ref. ASM 24-22/01) for a short to ground, a short circuit
R or an open circuit between:
R . pin B/12 of the IDG 1 and pin C/10 of the GCU 1
R . pin B/13 of the IDG 1 and pin C/11 of the GCU 1
R . pin B/14 of the IDG 1 and pin C/9 of the GCU 1
R . pins C/10, C/11, C/9 and C/7 of the GCU 1 (short to shield R of the PMG stator)
R . pin A/9 of the IDG 1 and pin C/12 of the GCU 1
R . pin A/10 of the IDG 1 and pin C/13 of the GCU 1
R . pins C/12, C/13 and pin C/7 of the GCU 1 (short to shield R of the exciter field).
R a_ If the wiring is not correct:
R - repair or replace as necessary.
R b_ If the wiring is correct:
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-001)
R and (Ref. AMM TASK 24-22-34-400-001).
R B. Do this operational test to make sure that the system operates correctly.
R (1) Aircraft Maintenance Configuration
R (a) Energize the aircraft electrical circuits
R (Ref. AMM TASK 24-41-00-861-002).
R (b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only)
R (Ref. AMM TASK 31-60-00-860-001).
R (2) On the ELEC panel 35VU:
R - push, release and push again the GEN 1 pushbutton switch (3XU1).
