Loss of the Accumulator Yellow-Pressure Indication on the Triple Indicator
(Electrical Failure)
1. Possible Causes
_______________
- PRESS XDCR-BRK,Y (3068GN)
- IND-BRK YELLOW PRESS TRIPLE (60GG)
- wiring from the pressure transducer (3068GN) pin A/F,B to the ground
- wiring from the pressure transducer (3068GN) to the triple indicator (60GG)

B. Pressurize the Yellow hydraulic system
(Ref. AMM TASK 29-24-00-863-001)
C. Test Make sure that there is no accumulator Yellow-pressure indication on the triple indicator.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- replace the PRESS XDCR-BRK,Y (3068GN) (Ref. AMM TASK 29-32-11-000-004) and (Ref. AMM TASK 29-32-11-400-004).
(1) If the fault continues:
- replace the IND-BRK YELLOW PRESS TRIPLE (60GG) (Ref. AMM TASK 32-44-21-000-001) and (Ref. AMM TASK 32-44-21-400-001).
(a) If the fault continues:
- do a check for a ground signal at pins A/F, B of the pressure transducer (3068GN) (Ref. ASM 32-44/01).
1 If there is no ground signal:
_
- repair the wiring from the pressure transducer (3068GN) pin A/F,B to the ground (Ref. ASM 32-44/01).
2 If there is a ground signal:
_
- do a check for continuity from the pressure transducer (3068GN) pin A/A to the terminal block (7502VT) pin 2/J (Ref. AWM 32-44-01).
a If there is no continuity:
_ - repair the related wiring (Ref. AWM 32-44-01).
b If there is continuity:
_
- do a check and repair the wiring from the pressure transducer (3068GN) to the triple indicator (60GG): pins A/D, E to pins A/D, E (Ref. ASM 32-44/01).
B. Test Make sure that there is an accumulator Yellow-pressure indication on the triple indicator.
5. Close-up
