R (b) If all the circuit breakers are closed:
R - stop the engine 2 (Ref. AMM TASK 71-00-00-710-043)
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 2
R (load side) and the loads (Ref. ASM 24-51/03).
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 2 and the load side (Ref. ASM 24-51/03).

R (a) If there is a short to ground:
R - repair or replace as necessary.
R (b) If there is no short to ground:
R - energize the aircraft electrical network from the external
R power (Ref. AMM TASK 24-41-00-861-002)
R - start the engine 2 only (Ref. AMM TASK 71-00-00-710-043) and
R close one by one the circuit breakers until the warning GEN 2
R OVERLOAD is shown. Repair the wiring or the component of the
R defective circuit.
R D. Do this test to make sure that the failure is repaired:
R (1) Make sure that the circuit breakers are closed (if the circuit
R breakers are not closed, close them).
R (2) Energize the aircraft electrical circuit from the external power
R (Ref. AMM TASK 24-41-00-861-002).
R (3) On the ELEC panel 35VU, make sure that the ELEC/GALLEY pushbutton
R switch is pushed.
R (4) Start the engine 2 (Ref. AMM TASK 71-00-00-710-003).
R (5) After five minutes, make sure that, on the upper ECAM DU, the warning
R GEN 2 OVERLOAD is not shown.
R (6) Stop the engine 2 (Ref. AMM TASK 71-00-00-710-028).

R A. Put the aircraft back to its initial configuration.
R (1) De-energize the aircraft electrical circuits from the external power

Operational Check of GAPCU via CFDS
R (1) Do the BITE test of the GAPCU (Ref. AMM TASK 24-41-00-740-002).
R NOTE : If the CFDS message PB BUS TIE (10XU) / BTC1 (11XU1) / GCU1
____ R (1XU1) comes into view when the flight crew or the maintenance R personnel puts the BUS TIE pushbutton switch (10XU) in the R released or OFF position the trouble shooting is not R necessary. This can occur during an electrical system test or R during trouble shooting. R If the flight crew or the maintenance personnel did not R operate the BUS TIE pushbutton switch and this CFDS message R comes into view, do the trouble shooting procedure that R follows.
R (a) If the BITE test gives the message TEST FAILED: R - do the trouble shooting given in Para 4.A.
R (b) If the BITE test gives the message TEST PASSED: R - do the trouble shooting given in Para 4.B.
