R b If the wiring is correct:_
R - do a check of the IDG 1 feeders for a phase-neutral
R reversal condition (Ref. ASM 24-22/01).
R * If there is a reversal:
R - remove and correctly install the feeders.
R * If the feeders are correctly installed:
R - replace the GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-000-
R 001) and (Ref. AMM TASK 24-22-34-400-001).
R ** If the fault continues:
R -- replace the engine 1 IDG (4000XU) (Ref. AMM TASK 24-
R 21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).
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).
R (3) Do the operational test of the GAPCU (Ref. AMM TASK 24-41-00-740-
R 002).
R (4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
R (5) Do this test:

R A. Put the aircraft back to its initial configuration.
R (1) Stop the engine 1 (Ref. AMM TASK 71-00-00-710-028).
R (2) Do the EIS stop procedure
R (Ref. AMM TASK 31-60-00-860-002).
R (3) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY
R potentiometers to OFF.
