B. Aircraft Maintenance Configuration
(1) Open the access panel 197EB.
(2) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(3) On the RAT ground control-panel (3GE):
- Set the 28VDC switch to the ON position.
- Set the LAMP TEST switch to the test position and make sure that all lights come on.

(4) Retract the RAT (Ref. AMM TASK 29-22-00-869-006).
(5) During the retraction of the RAT:
- Obey the interlock warning light in the RAT control panel (3GE).
- Obey the operation of the RAT.
4. Fault Isolation
_______________
A. If the RAT starts to retract but returns to its fully extended position and the interlock warning light on the RAT control panel (3GE) comes on:
- Do the adjustment of the RAT interlock proximity switch (Ref. AMM TASK 29-22-00-820-005).
(1) If the fault continues:
- Replace the RAT interlock proximity switch (Ref. AMM TASK 29-22-51-000-011) and (Ref. AMM TASK 29-22-51-400-011).

________
A. Put the aircraft back to the serviceable condition.
(1) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
(2) Close the access panel 197EB.

3. Fault Confirmation
__________________
A. Do the operational test of the ram air turbine (RAT) automatic deployment (Ref. AMM TASK 29-22-00-710-001).
4. Fault Isolation
_______________
A. If the RAT extends as soon as the circuit breaker 9XE or 11XE is opened during the operational test:
- Replace the RELAY-EMER AUTO LOG CONDITION (17XE) if the RAT extends when you open the circuit breaker 9XE.
- Replace the RELAY-EMER AUTO LOG CONDITION (18XE) if the RAT extends when you open the circuit breaker 11XE.
B. Do the test as given in Para. 3. A. to make sure that the operation is correct.
