Subtask 24-21-00-860-056-A
A. Job Set-up
   (1) Aircraft Maintenance Configuration
     (a) Energize the aircraft electrical circuits
AMM 24-41-00-861-002.
     (b) Do the EIS start procedure (lower ECAM DU only) AMM 31-60-00-860-001.
Subtask 24-21-00-710-077-A
B. Test
ACTION
RESULT
1.On the ECAM control panel:
  • push the ELEC key to get the ELEC page.
If on the lower ECAM DU:
  • amber crosses replace the oil temperature indication of the IDG1,
    do the trouble shooting given in Para. 4.A.
4. Fault Isolation
Subtask 24-21-00-810-073-B ** ON A/C NOT FOR ALL
A. If the test confirms the fault:
   (1) If the fault continues:
   (2) If the fault continues:
  • do a check and repair the wiring between ASM 242101:
    . the pin AB/7 of the IDG1 (4000XU) and the pin AA/8A of the GCU1 (1XU1)
    . the pin AB/8 of the IDG1 (4000XU) and the pin AA/9B of the GCU1 (1XU1)
    . the pin AB/9 of the IDG1 (4000XU) and the pin AA/9A of the GCU1 (1XU1)
  • do a check and repair the wiring between ASM 242202:
    . the pin AB/9A of the GCU1 (1XU1) and the pin AA/4C of the EGIU1 (22XU1)
    . the pin AB/9B of the GCU1 (1XU1) and the pin AA/4D of the EGIU1 (22XU1)
    . the pin AB/9C of the GCU1 (1XU1) and the pin AA/5A of the EGIU1 (22XU1). Then make sure that the ground wire is correctly connected to the pin AA/5C of the EGIU1 (22XU1).
  • do a check and repair the wiring between ASM 315403:
    . the pin AA/1A of the EGIU1 (22XU1) and the pin AB/10G of the SADC1 (1WV1)
    . the pin AA/1B of the EGIU1 (22XU1) and the pin AB/10H of the SADC1 (1WV1)
    . the pin AA/1C of the EGIU1 (22XU1) and the pin AB/10G of the SADC2 (1WV2)
    . the pin AA/1D of the EGIU1 (22XU1) and the pin AB/10H of the SADC2 (1WV2)
   (3) If the fault continues:
Subtask 24-21-00-810-073-D ** ON A/C NOT FOR ALL
A. If the test confirms the fault:
   (1) If the fault continues:
  • do a check and repair the wiring between ASM 242101:
    . the pin AB/7 of the IDG1 (4000XU) and the pin AA/9C of the GCU1 (1XU1)
    . the pin AB/8 of the IDG1 (4000XU) and the pin AA/9D of the GCU1 (1XU1)
    . the pin AB/9 of the IDG1 (4000XU) and the pin AA/10C of the GCU1 (1XU1)
  • do a check and repair the wiring between ASM 315403:
    . the pin AA/8F of the GCU1 (1XU1) and the pin AB/10G of the SADC1 (1WV1)
    . the pin AA/7F of the GCU1 (1XU1) and the pin AB/10H of the SADC1 (1WV1)
    . the pin AA/8J of the GCU1 (1XU1) and the pin AB/10G of the SADC2 (1WV2)
    . the pin AA/8H of the GCU1 (1XU1) and the pin AB/10H of the SADC2 (1WV2)
   (2) If the fault continues:
Subtask 24-21-00-710-078-A
B. Do this test to make sure that the system operates correctly:
ACTION
RESULT
1.On the ECAM control panel:
