 4. Fault Isolation
_______________
 A. If the fault symptom is identified by the CFDS message IDG COOLER 1 and the warning IDG1 OIL OVHT on the upper ECAM DU:
 - replace the IDG1 oil cooler (Ref. AMM TASK 73-11-60-000-002) and (Ref. AMM TASK 73-11-60-400-002).
 (1) If the fault continues:
 - do a check for cooler tubing blockage and replace the IDG1 oil cooling tubing which is blocked (Ref. AMM TASK 24-21-49-000-003) (Ref. AMM TASK 24-21-49-000-004) and (Ref. AMM TASK 24-21-49-400-003) (Ref. AMM TASK 24-21-49-400-004).
 B. Do this operational test to make sure that the system operates correctly.
 (1) 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).

 (2) On the ELEC panel 35VU:

 - push, release and push again the GEN1 pushbutton switch (3XU1).

 (3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).

 (4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).

 C. Do this test:
 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: On the lower ECAM display unit:
 - get the ELEC page.  - the correct electrical parameters of GEN1 are shown and AC1 busbar is supplied by GEN1.
 5. Close-up
________
 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).
