A. Job Set-up
(1) Push the ELEC/BAT 2 pushbutton switch (7PB2).
(2) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).

CES B. Test
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: - push the ELEC key to get the ELEC page. On the upper ECAM DU:- the BAT 2 OFF message comes intoview.
2. On the ELEC panel 35VU: - release and push the BAT 2 pushbutton switch (7PB2). If on the upper ECAM DU:- the BAT 2 OFF message goes out ofview, stop the trouble shooting. If on the upper ECAM DU: - the BAT 2 OFF message stays in view, continue the trouble shooting (refer to the fault isolation which
follows).
4. Fault Isolation_______________

B. If the test confirms the fault:
- open the circuit breakers 30LP, 8PB2 and 9PB2
- replace the P/BSW-ELEC/BAT 2 (7PB2) (Ref. AMM TASK 33-10-00-000-002) and (Ref. AMM TASK 33-10-00-400-002)
- close the circuit breakers 30LP, 8PB2 and 9PB2.
(1) If the fault continues:
- do a check of the wiring: . from the pin A/A3 of the ELEC/BAT 2 pushbutton switch (7PB2) to the DC1 ground (Ref. ASM 24-38/02), (Ref. AWM 24-38-06) and (Ref. AWM 24-91-06) . from the pin A/A2 of the ELEC/BAT 2 pushbutton switch (7PB2) to the pin 11Y of the first terminal block 2407VT (Ref. ASM 24-38/02) and (Ref. AWM 24-38-06) . from the pin 11P of the first terminal block 2407VT to the pin 25M of the second terminal block 1862VT (Ref. ASM 24-38/02) and (Ref. AWM 31-54-28) . from the pin 25E of the second terminal block 1862VT to the pin AD/7H of the SDAC1 (1WV1) (Ref. ASM 24-38/02) and (Ref. AWM 31-54-28)

(a) If there is no continuity:
- repair the wiring.
C. Do the test given in Para. 3.
5. Close-up________
A. Put the aircraft back to its initial configuration.
(1) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
