- do a check and repair the wiring of the RA2 INPUT bus from the DMC2 (1WT2) to the first terminal block (Ref. ASM 34-42/02).
(b) If the radio altitude indication is not shown:
- replace the XCVR-RA, 2 (2SA2) (Ref. AMM TASK 34-42-33-000-001) and (Ref. AMM TASK 34-42-33-400-001).
1_ If the fault continues:
- do a check and repair the wiring of the ALTITUDE BUS 2 from
the RA transceiver 2 (2SA2) to the first terminal block
(Ref. ASM 34-42/02).
B. Do the test given in Para. 3.
