TM 55-4920-328-13 d.    Connect the positive (+) lead of cable assembly (12, figure 2-44) to terminal C on the starter assembly. Connect  the  negative  (-)  lead  of  the  cable  assembly  to terminal E on the starter assembly.  Insert the connector on  the  opposite  end  to  the  mating  receptacle  on  the electric start system. e. Open the door of the trailer assembly cable tray and   connect   the   following   cable   assemblies   to   the respective connectors in the data acquisition assembly: (1)   Connect cable assembly W1 to J1. (2)   Connect cable assembly W2 to J2. (3)   Connect cable assembly W3 to J3. (4)   Connect cable assembly W4 to J4. (5)   Connect cable assembly W5 to J5. (6)   Connect cable assembly W6 to J6. f. Attach   the   hose   assembly   (13)   to   the   water brake water return connection and attach the other end of  the  hose  assembly  to  the  mating  quick-disconnect coupling on the test trailer frame. g. Connect  the  hose  assembly  (14)  to  the  lower fitting on the water brake supply manifold assembly, and connect the other end of the hose assembly to the water supply   quick-disconnect   coupling   on   the   test   trailer frame. h. Connect   the   quick-disconnect   coupler   on   the hose  assembly  (15)  to  the  water  brake  bearing  water supply coupling on the test trailer frame. i. Connect the coupler on the hose assembly (16) to the water brake air supply coupling on the test trailer frame. j. Connect the coupler on the hose assembly (17) to the fuel supply coupling on the test trailer frame. k.    Connect the coupler on the hose assembly (18) to the T74 oil supply coupling on the test trailer frame. I. Connect the coupler on the hose assembly (19) to the oil return coupling on the test trailer frame. m.    Provide  overboard  drain  containers  and  place an overboard drain hose assembly in each container. n. Connect    the    NI    throttle    control    linkage    as outlined in paragraph 2-52. 2-52. Installation of T74 NI Controls. Install the NI control linkage as shown in figure 2-45, observing the following: a. Install  the  bracket  (1)  on  the  engine  test  dolly mount ring, using four bolts (2) and four washers (3). NOTE The    NI    slave    unit    specified    in    the following step is a part of the permanently-connected test trailer equipment. b. Install  the  NI  slave  unit  (4)  on  the  bracket  (1), using  three  bolts  (5),  three  washers  (7),  and  three  nuts (6). c. Install one nut (8) and one rod end (9) on each end of the rod (10).  Do not tighten the nuts at this time. d. Adjust the center-to-center distance between the holes  in  the  rod  ends  (9)  to  20.25  inches,  then  tighten the nuts (8). e. Disconnect  the  aft  end  of  the  fuel  control  unit control rod (11) from the control lever (12).  Reinstall the attaching   parts   in   the   free   end   of   the   control   rod   to facilitate reinstallation after engine test. f. Secure the control rod (11) to a non-moving part on   the   engine.      Ensure   freedom   from   interference between the control rod and engine parts or accessories. g. Attach one end of the rod (10) (and assembled parts)  to  the  upper  hole  in  the  control  lever,  using  the bolt (13), spacer (14), washer (15), and nut (16). h.    Position the NI master control unit in the control cab  to  align  the  rod  end  (9)  with  the  end  hole  in  the slave unit lever arm. i. Attach the other end of the rod (10) to the lever arm  of  the  slave  unit,  using  the  bolt  (18),  spacer  (17), washer (19), and nut (20). j. Position   the   NI   linkage   such   that   the   control lever  (12)  is  at  Ground  Idle.    (The  master  control  unit lever  arm  will  automatically  move  to  the  corresponding position in the control cab.) k. Use    a    non-destructive    pencil,    to    mark    the Ground Idle position on the master control unit quadrant, then measure 56 degrees of arc on the quadrant in the forward   (throttle   advanced)   direction   and   mark   this point. 2-172
