Remove  M-91  test  set  from  right  fuselage dispenser assembly. c. Chaff   Dispenser   (Right   Nacelle)   -   Preliminary Procedure. 1. C-F    selector     switch     on     dispenser C (chaff). 2. Set  TEST SEQUENCE  switch  on  test  set to START/HOME position. 3. Clean  dust,  foreign  particles,  or  moisture from breech and mounting plate of dispenser. 4. Connect M-91 test set to breech assembly of right nacelle dispenser assembly. Secure    both    mounting    studs    uniformly tight  using  ball  hexagonal  key  screwdriver provided in test set carrying case. 5. Obtain   test   set   power   cable   from   loose tools  and  connect  cable  between  exterior connection J1 (28V DC) on aircraft fuselage  above  trailing  edge  of  wing  and aircraft power +28V DC (J1) of test set. 6. Remove  safety  pins  from  right  equipment rack  aft  of  copilot's  seat,  and  on  top  skin of right wing. 7. Provide     aircraft     power     to     system     by resetting M-130 POWER circuit breaker. 8. ASE    mode    select    switch    (multifunction display,  fig.    4-2)  Depress  to  call  up   ASE control page. 9. L3   line   selector   switch   Depress   to   set DISPENSER to ARM. 10. L4   line   selector   switch   Depress   to   set CHAFF to MAN. 11. R5  line  selector  switch  Depress  to  call  up ASE SETUP page. 12. ASE/ACS keyboard  unit  (fig.    4-3)  Key  in 30  (30  will  be  displayed  in  scratchpad  on MFD),  then  depress  line  select  switch  R1 to set CHAFF COUNT to 30. NOTE When  the  test  set  is  installed  on  the dispenser  assembly  and  28  volts  DC aircraft  power  is  being  applied,  the sequence switch inside the dispenser assembly  resets,  making  an  audible sound as it rotates.  There will be no such  sound  if  the  sequencer  switch has been previously reset or if switch is in position 12 or 24. d. Chaff   Dispenser   (Right   Nacelle)   System   Test Procedure. 1. ASE   mode   selector   switch   Depress   to return to the ASE control page. 2. Reinstall  safety  pins  one  at  a  time.    PWR FAIL  shall  appear  below  DISPENSER  on MFD. 3. Remove the safety pins and verify DISPENSER is set to ARM on MFD. 4-7
