 - 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 (8077KM) (Ref. AMM TASK 49-91-42-200-004).
 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).
