R 4. Fault Isolation_______________
R A. If the test confirms the fault:
R - do a check of the connector A of the TR-2 (1PU2) for correct condition.
R (1) If the connector is not in the correct condition (burned contacts,
R damaged contacts...):
R - replace it.
R (2) If the connector is in the correct condition:
R - do a check of the wiring between pins A2, B2 and C2 of the TR-2
R SPLY circuit breaker (2PU2) and pins A/A, A/B and A/C of the TR-2
R (1PU2). (Ref. ASM 24-32/01)
R (a) If the fault continues:
R - do a check of the connector B of the TR-2 (1PU2) for correct
R condition.
R 1_ If the connector is not in the correct condition:
R - replace it.
R 2_ If the connector is in the correct condition:
R - do a check and repair the wiring from the TR-2 pins B/A, B/B
R and B/C to the first terminal block (Ref. ASM 24-32/01).
R B. Do this test

R A. Put the aircraft back to its initial configuration.
R (1) Do the EIS stop procedure
R (Ref. AMM TASK 31-60-00-860-002).
R (2) De-energize the aircraft electrical circuits
R (Ref. AMM TASK 24-41-00-862-002).
