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

B. If the test confirms the fault:
- open the circuit breakers 8XA and 1XA
- replace the P/BSW-ELEC/GALLEY (2XA) (Ref. AMM TASK 33-10-00-000-002) and (Ref. AMM TASK 33-10-00-400-002)
- close the circuit breakers 8XA and 1XA.
(1) If the fault continues:
- remove the GCU1 (1XU1) (Ref. AMM TASK 24-22-34-000-001)
- close the circuit breaker 2XU1.
(a) If the fault does not continue:
- install a new GCU-1 (1XU1) (Ref. AMM TASK 24-22-34-400-001).
(b) If the fault continues:
- open the circuit breakers 8XA and 1XA
- disconnect the connector of the diode module 1162VD (Ref. IPC 25710104)
- close the circuit breakers 8XA and 1XA.
