R 1_ If the fault does not continue:
R - open the circuit breakers 8XA and 1XA
R - replace the diode module 1162VD (Ref. IPC 25710104)
R - install the GCU 1 (1XU1) (Ref. AMM TASK 24-22-34-400-001)
R - close the circuit breakers 8XA and 1XA.
R 2_ If the fault continues:
R - open the circuit breakers 8XA and 1XA
R - do a check and repair the wiring between the pin A/14 of the
R diode module 1162VD and the pin AA/6G of the GCU 1 (1XU1)
R - connect the connector of the diode module 1162VD (Ref. IPC
R 25710104)
R - install the GCU 1 (1XU1) (Ref. AMM TASK 24-22-34-400-001)
R - close the circuit breakers 8XA and 1XA.

1. On the ECAM control panel: - push the ELEC key to get the ELEC page. On the upper ECAM DU:- the GEN 2 OVERLOAD message comes intoview.
2. On the ELEC panel 35VU: - release the GALLEY pushbutton switch (2XA). If on the upper ECAM DU:- the GEN 2 OVERLOAD message goes outof view, stop the trouble shooting. If on the upper ECAM DU: - the GEN 2 OVERLOAD message stays in view, continue the trouble shooting (refer to the fault isolation which follows).
