A. Test
(1) Do the functional test of the tachometers.(Ref. AMM TASK 32-42-00-720-002)
4. Fault Isolation
_______________
A. If the test confirms the fault:
- inspect the two tachometer drives
(1) If the tachometer drives are damaged:
- replace the DRIVE ASSY-TACHOMETER,WHEEL 1 (2681GM) and DRIVE ASSY-TACHOMETER,WHEEL 2 (2680GM) (Ref. AMM TASK 32-42-68-000-003) (Ref. AMM TASK 32-42-68-400-003)
(2) If the tachometer drives are not damaged:
- replace the TACHOMETER-WHEEL 1 (19GG) and TACHOMETER-WHEEL 2 (21GG) (Ref. AMM TASK 32-42-57-000-001) (Ref. AMM TASK 32-42-57-400-001)
(3) If the fault continues:
- do a check and repair the wiring from the tachometers to the BSCU (10GG). (Ref. ASM 32-42/02)
