4. Fault Isolation
_______________
A. If the test confirms the fault: - do a check of the wiring from the essential transformer rectifier pins B/B and B/C to the first terminal block (Ref. ASM 24-34/01).
(1) If there is no continuity: - repair the wiring.
(2) If there is continuity: - replace the TR-ESS (1PE)> (Ref. AMM TASK 24-34-51-000-001) and (Ref. AMM TASK 24-34-51-400-001).
B. Do this test to make sure that the system operates correctly.
-------------------------------------------------------------------------------
ACTION RESULT -------------------------------------------------------------------------------
1. On the ECAM control panel: - push the ELEC key to get the ELEC page. On the lower ECAM DU:- the ELEC page comes into view.
R R R R In the ESS TR box: - the value of the ESS TR current is shown in green.
