R (1) Aircraft Maintenance Configuration

R (a) Energize the aircraft electrical circuits from the external power
R (Ref. AMM TASK 24-41-00-861-002).
R (2) On the ELEC panel 35VU, make sure that the ELEC/GEN 1 pushbutton

R switch (3XU1) is pushed.

R (3) On the ELEC panel 35VU, make sure that the ELEC/GALLEY pushbutton
R switch (2XA) is pushed (the OFF legend is off).
R B. Test
R (1) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
R (2) On the upper ECAM DU, the warning GEN 1 OVERLOAD is shown.

R  B. If the test confirms the fault: 

R - in the AC power center panel 123VU, do a check of the circuit breakers
R 1MC and 12MC.

R (1) If the circuit breakers 1MC and/or 12MC are open:
R - replace the MAIN/GALLEY C/PWR/SPLY (1MC) and/or the AFTER GALLEY
R FEEDER B (12MC).

R (2) If the circuit breakers 1MC and 12MC are closed:
R - on the AC power center panel 123VU, do a check of the status of the
R circuit breakers 5XN1, 3XN1, 7XN1, 1DG1, 1XC, 2701GJ, 1HQ, 1XN1 and
R 2PU1.

R (a) If one or more circuit breaker(s) is(are) open:
R - do a check of the loads downstream of the open circuit
R breaker(s) for a short to ground or a defective component.

R (b) If all the circuit breakers are closed:
R - stop the engine 1 (Ref. AMM TASK 71-00-00-710-003)
R - de-energize the aircraft electrical network from the external
R power (Ref. AMM TASK 24-41-00-862-002) and do the procedure
R that follows.

R C. Do a check of the AC/DC main power center 120VU:
R - open the AC/DC main power center 120VU and do a check of the wiring for
R a short circuit or a short to ground between downstream of the GLC 1
R (load side) and the loads (Ref. ASM 24-51/02).

R (1) If the wiring is not correct:
R - repair or replace as necessary.

R (2) If the wiring is correct:
R - do a check of the feeders for a short to ground, a short circuit or
R a related defective equipement between the pins R, M, G, P, L, H,
R N, K and J of the GLC 1 and the load side (Ref. ASM 24-51/02).
