____ NO ACCELERATION - ACFT BAT NOT SELECTED / CONTACTOR (5KA) APU Auto Shut Down Fault Code Number: 051
although the A/C batteries are selected ON:
- do a check for continuity of the aircraft wiring from the ECB (59KD) AC/1 to the START CONTACTOR (5KA) B/3 (Ref. ASM 49-42/01).
(1) If there is no continuity:
- repair the aircraft wiring.
(2) If there is continuity:
- do a check for a ground signal (with APU MASTER SW pushed) at the MAIN START CONTACTOR (5KA) B/5 (Ref. ASM 49-42/01).
(a) If there is a ground signal:
- replace the CONTACTOR-MAIN START 5KA.
(b) If there is no ground signal:
1_ If the fault continues:
- replace the ECB 59KD (Ref. AMM TASK 49-61-34-000-002) and
(Ref. AMM TASK 49-61-34-400-002).
- replace the APU MASTER SW (14KD).
1 If the fault continues:
_
- do a check and repair of the aircraft wiring between the MAIN START CONTACTOR (5KA) B5 and the terminal block 2266VT/4 (Ref. AWM 49-42-01).
B. Do the test given in para. 3.
