- no lights in the cockpit come on,
- the static inverter does not start,
do the trouble shooting given in Para. 4.C.
(2) If during the test:
- the FAULT legend of the FAC 1 pushbutton switch comes on
- the upper ECAM DU is blank
- with the INT LT/DOME switch (25VU) in the BRT position, the F/O
DOME lights (452VU) are on,
do the trouble shooting given in Para. 4.A.
(3) If during the test:
- the upper ECAM DU is blank
- the FAULT legend of the FAC 1 pushbutton switch goes off
- with the INT LT/DOME switch (25VU) in the BRT position, the F/O
DOME lights (452VU) are on,
do the trouble shooting given in Para. 4.B.
(4) If during the test:
- the upper ECAM DU is blank
- the OFF legends of the BAT 1 and BAT 2 pushbutton switches go off
- with the INT LT/DOME switch (25VU) in the BRT position, the F/O
DOME lights (452VU) are not on,
do the trouble shooting given in Para. 4.C.
(5) If during the test:
- when the BUS TIE pushbutton switch is released, the normal
electrical configuration stays in view on the lower ECAM DU, do the trouble shooting given in Para. 4.D.
(6) If during the test:
- XX is shown as an alternative to the numerical STAT INV voltage and frequency values
- you think all the systems normally supplied in this configuration
are correctly supplied,
do the trouble shooting given in Para. 4.E.

4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the status of the circuit breaker 10XE.
(1) If the circuit breaker is open:
- close it.
(a) If the circuit breaker trips:
- do a check of the wiring for short to ground from the pin 1 of the circuit breaker (10XE) to the AC ESS BUS SWITCHING contactor.
1 If the wiring is correct:
_ - replace the C/B - AC ESS BUS/EMER/STBY/CNTOR/SPLY (10XE).
2 If the wiring is not correct:
_ - repair it.
(2) If the circuit breaker is closed:
- replace the RELAY (7XB), RELAY - CNTOR 3XC MONG, 1 (13XC), RELAY -CNTOR 3XC MONG, 2 (14XC).
(a) If the fault continues:
- replace the CNTOR-AC ESS BUS SWITCHING (15XE) (Ref. AMM TASK 24-24-55-000-002) and (Ref. AMM TASK 24-24-55-400-002).
(b) If the fault continues:
- do a check and repair the wiring from the circuit breaker (10XE) to the contactor (15XE) (Ref. ASM 24-24/02).
B. If the test confirms the fault:
- replace the STAT INV (3XB) (Ref. AMM TASK 24-28-51-000-001) and (Ref. AMM TASK 24-28-51-400-001).
C. If the test confirms the fault:
(1) Do a check of the battery 1 (2PB1) and the battery 2 (2PB2) voltage.
(a) If the voltage is not correct (less than 23 VDC):
- replace the BAT-1 (2PB1) or/and the BAT-2 (2PB2) (Ref. AMM TASK 24-38-51-000-001) and (Ref. AMM TASK 24-38-51-400-001).
(b) If the voltage is correct (more than 25.5 V), do the step that follows:
(2) Do a check for 28 VDC at the coil of the relay (7XB).
(a) Do a check of the status of the circuit breaker (14XB):
1 If the circuit breaker is open:
_ - close it.

Feb 01/98 CES a If the circuit breaker trips:
_
- do a check of the wiring for short to ground from the circuit breaker (14XB) to the coil of the relay (7XB) and the coil of the contactor (2XB).
* If the wiring is correct:
- replace the C/B - ELEC/STAT INV/CNTOR/CTL (14XB).
* If the wiring is not correct:
- repair it.
2 If the circuit breaker is closed:
_
- push the EMER ELEC PWR/EMER GEN TEST pushbutton switch (23XE) and do a check for 28 VDC between the pin A/X1 or A/A1 and the pin A/X2 of the relay (7XB).
a If there is no 28 VDC:
