(2) If the circuit breaker is closed:
- do a check of the wiring for open circuit: . from the GCU 2 pin B/2D to successively the GLC 2 pin B/3, EGIU 2 pin A/12A, GCU 2 pin A/5B, . from the GCU 2 pin A/12D to the EGIU 2 pin A/13A, . from the GCU 2 pin A/12C to the pin X/1 of the current transformer 4XU2, . from the pin X/2 of the current transformer 4XU2 to the ground, . from the GLC2 pin B/5 to the ground (Ref. ASM 24-22/02).
(3) If there is no continuity:
- repair the above defective wiring.
(4) If there is continuity:
- do a check of the EGIU 2 wiring for open circuit from pin A/12A to pin A/13A.
(a) If there is no continuity:
- replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
(b) If there is continuity:
- replace the GLC-2 (9XU2) (Ref. AMM TASK 24-22-55-000-001) and (Ref. AMM TASK 24-22-55-400-002).
(c) If the fault continues:
- replace the RELAY-GLC2 AUX CTL (4XU2).
(d) If the fault continues:
- replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
B. Do this operational test to make sure that the system operates correctly.
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).

(2) On the ELEC panel 35VU:
- push, release and push again the GEN 2 pushbutton switch (3XU2).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 2 (Ref. AMM TASK 71-00-00-710-003).
C. Do this test:

On the ECAM control panel: On the lower ECAM display unit:
- get the ELEC page. - the correct electrical parameters of GEN 2 are shown and AC 2 busbar is supplied by GEN 2.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 2 (Ref. AMM TASK 71-00-00-710-028).
(2) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF.
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
