 4. Procedure
_________ R Subtask 52-51-00-040-058
 A. Deactivation of the Electrical Release Strike
 (Ref. Fig. 402/TASK 52-51-00-991-011)

 (1)
 Turn the D-ring of the latch mechanism and open the cockpit door.

 (2)
 Manually move the catch of the defective electrical release strike to check that it moves freely.

 (3)
 If the plunger causes a blockage of the catch, remove the defective electrical release strike (Ref. TASK 52-51-12-000-001).

 NOTE : Do not disconnect the jiffi junction connectors at the A/C
____ wire harness for isolation reasons to prevent a short circuit.
 (4) If the catch moves freely, disconnect the A/C wire harness from the applicable electrical release strike cables (Ref. ESPM 204825) and (Ref. AWM 52-51-02).
 NOTE : Do not disconnect the jiffi junction connectors at the A/C
____ wire harness for isolation reasons to prevent a short circuit.
 (5)
 Make sure that the remaining electrical release strikes operate satisfactorily (Ref. TASK 52-51-00-710-001).

 (6)
 Put a warning notice on the door post to tell persons that the applicable elecrtical release strike is deactivated or removed.
