3. Fault Confirmation
__________________
A. Job Set-up
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(3) Start the APU:
- GTCP 36-300 (Ref. AMM TASK 49-00-00-860-003)
or
- APS 3200 (Ref. AMM TASK 49-00-00-860-005)
or
- 131-9(A) (Ref. AMM TASK 49-00-00-860-008).
B. Test
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: On the upper ECAM DU:
- push the ELEC key to get the - the APU GEN OVERLOAD message comes ELEC page. into view.
2. On the ELEC panel 35VU: If on the upper ECAM DU:
- release the GALLEY pushbutton - the APU GEN OVERLOAD message goes out
switch (2XA). of view, stop the trouble shooting. If on the upper ECAM DU:
- the APU GEN 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 APU GCU (1XS) (Ref. AMM TASK 24-23-34-000-001)
- close the circuit breaker 2XU1.
(a) If the fault does not continue:
- install a new GCU-APU (1XS) (Ref. AMM TASK 24-23-34-400-001).
(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.
1 If the fault does not continue:
_ - open the circuit breakers 8XA and 1XA
- replace the diode module 1162VD (Ref. IPC 25710104)
- install the APU GCU (1XS) (Ref. AMM TASK 24-23-34-400-001)
- close the circuit breakers 8XA and 1XA

Aug 01/05 CES 2 If the fault continues:
_
- replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
a If the fault does not continue:
_ - open the circuit breakers 8XA and 1XA
- connect the connector of the diode module 1162VD (Ref. IPC 25710104)
- install the APU GCU (1XS) (Ref. AMM TASK 24-23-34-400-001)
- close the circuit breakers 8XA and 1XA.
b If the fault continues:
_ - open the circuit breakers 8XA and 1XA
- do a check and repair the wiring between: . the pin A/11 of the diode module 1162VD and the pin AA/13B of the APU GCU (1XS) . the pin A/11 of the diode module 1162VD and the pin AB/10A of the EGIU2 (22XU2) . the pin A/11 and the pin A/10 of the diode module 1162VD
- connect the connector of the diode module 1162VD (Ref. IPC 25710104)
- install the APU GCU (1XS) (Ref. AMM TASK 24-23-34-400-001)
- close the circuit breakers 8XA and 1XA.
