- do a check of the aircraft BATTERIES (Ref. AMM TASK 24-38-00-210-001).
(1) If the fault continues:
- do a check for APU internal damage.
- do a check for contamination of the MAGNETIC-DRAIN PLUG (Ref. AMM TASK 49-91-42-200-001).
NOTE : If the MAGNETIC-DRAIN PLUG is not contaminated, continue
____
without starting the APU.
- .
- remove the end cap of the STARTER MOTOR (8KA).
- use a socket and a ratchet on the shaft of the STARTER MOTOR (8KA) to turn the APU counterclockwise (in the direction of the arrow on the housing).
- make sure that the APU rotates freely.
(a) If the APU rotates freely:
- replace the APU GENERATOR (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001).
1 If the fault continues:
_
- replace the STARTER MOTOR CLUTCH (Ref. AMM TASK 49-42-52-000-001) and (Ref. AMM TASK 49-42-52-400-001).
2 If the fault continues:
_
- replace the STARTER MOTOR (8KA) (Ref. AMM TASK 49-42-51-000-002) and (Ref. AMM TASK 49-42-51-400-002).
3 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
(b) If the APU does not rotate freely:
- replace the APU (4005KM)
B. Do the test given in para. 3.
