1 If the circuit breaker trips again:
_
- replace the DME receiver 2 (Ref. AMM TASK 34-51-33-000-001) and (Ref. AMM TASK 34-51-33-400-001).
(b) If this circuit breaker trips again:
- do a check for a short to ground at the wiring between the circuit breaker (1SD2) and the DME receiver 2 (2SD2) (Ref. ASM 34-51/01).
1 If there is a short to ground:
_ - repair the above wiring.
2 If there is no short to ground:
_ - replace the C/B-NAV/DME 2 (1SD2).
3 Install the DME receiver 2
_ (Ref. AMM TASK 34-51-33-400-001).
D. Do the test given in Para. 3.
