 3. Fault Confirmation
__________________
 A. Do the operational test of the Anti-Collision/Strobe Lighting and confirm that the upper anti-collision beacon light does not flash (Ref. AMM TASK 33-48-00-710-001).
 4. Fault Isolation
_______________
 A. If the test confirms the fault:
 - replace the LIGHT-BEACON, UPPER (7LV) (Ref. AMM TASK 33-48-11-000-001) and (Ref. AMM TASK 33-48-11-400-001).
 (1) If the fault continues:

 - do a check for 200 VAC at the PWR SPLY UNIT 3LV connectors A/1, A/2 and A/3 (Ref. ASM 33-48/01).
 (a) If there is approx. 200 VAC:

 - replace the PWR SPLY UNIT-UPPER BEACON (3LV) (Ref. AMM TASK 33-48-36-000-001) and (Ref. AMM TASK 33-48-36-400-001).

 (b) If there is no 200 VAC:

 - do a check of the PWR SPLY-RELAY (8LV) and replace it if necessary.

 (2) If the fault continues:

 - do a check of the EX LT BEACON-SWITCH (2LV) and replace it if necessary.

 (3) If the fault continues:

 - do a check and repair the wiring between: CB 1LV conn. A2 to PWR SPLY-RELAY 8LV conn. A/A2, CB 1LV conn. B2 to PWR SPLY-RELAY 8LV conn. A/B2, CB 1LV conn. C2 to PWR SPLY-RELAY 8LV conn. A/C2, CB 1LV conn. C2 to EXT LT BEACON-SWITCH 2LV conn. 1A,
