- no trouble shooting is necessary.
(2) If the IDG1 has not been disconnected intentionally:
- reconnect the IDG1: for this, reset the disconnect system (Ref. AMM TASK 24-21-00-710-040) (the warning ELEC GEN1 FAULT is no longer shown of the upper ECAM display unit and the DISC indication is no longer shown on the lower ECAM display unit).

(a) If the IDG1 disconnects again (the warning GEN1 FAULT is shown again on the upper ECAM display unit and the DISC indication is shown again on the lower ECAM display unit):
- replace the RELAY-IDG1 DISC CTL (3XT).
1 If the fault continues:
_
- do a check and repair the wiring for abnormal 28VDC between the pin A/A1 of the relay (3XT) and the pin A/12 of the IDG1 (Ref. ASM 24-21/01).
(b) If the IDG1 does not disconnect:
- on the circuit breaker panel 122VU, open, safety and tag the circuit breaker ELEC/GCU/1 (2XU1).
1 If the IDG1 disconnects (the warning GEN1 FAULT is shown on
_ the upper ECAM display unit and the DISC indication is shown on the lower ECAM display unit).
- replace the P/BSW-ELEC/IDG1 (5XT).
a If the fault continues:
_
- do a check and repair the wiring for abnormal 28VDC between the pin A/B1 of the pushbutton switch (5XT) and the pin A/X1 of the relay (3XT) (Ref. ASM 24-21/01).
2 If the IDG1 does not disconnect:
_
- stop the trouble shooting and on the circuit breaker panel 122VU, remove the safety clip and tag and close the circuit breaker (2XU1).
B. Do this test to make sure that the system operates correctly:
(1) Make sure that the circuit breaker 2XU1 is closed.
(2) On the overhead panel, on the ELEC panel 35VU:
- push, release and push again the ELEC/GEN1 pushbutton switch (3XU1).
(3) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).
(4) Do this test:

________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 1 (Ref. AMM TASK 71-00-00-710-028).
(2) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF.
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
