TM 1-1520-240-BD • Bundle forming and protection. • Circular and flat connector repair. • Terminal board replacement. • Terminal lug installation. Prior  to  performing  any  of  the  listed  repairs,  the  repair technician  must  be  knowledgeable  in  the  application  of the basic repair procedures, and proficient in the use of wiring    repair    tools    and    materials.        The    techniques illustrated,  when  applicable,  duplicate  the  "short-form" instruction for each repair material that are affixed to the storage box cover. (1) Unshielded  Primary  Wire  Splicing.    The repair set provides wire splice capability for all 24 to 12 AWG wiring used on Army helicopters, regardless of the wire temperature ratings.  Splices are provided for wires rated   at   1050C   or   below   (wires   identified   as   M5086, MS26313,  M7078/3,  5,  7,  and  M27500  A,  B,  C,  P,  AA, AB,  or  AD);  TM  1-1520-240-BD  and  for  wires  rated  at 125°  C or above (wire identified as M22759/16, 18, 32, 34,  43  and  M81381/7,  11).    All  primary  wire  stocked  in the repair set is M22759/43, rated at 200°C.    This  wire may  be  spliced  to  any  existing  aircraft  wiring  provided that  the  splice  selected  is  appropriate  for  the  existing aircraft  wiring  temperature  rating.    Wire  bundle  repairs should  be  accomplished  using  the  splicing  techniques described  in  this  section.    Care  should  be  exercised  to stagger   splices.      Where   possible,   splices   in   adjacent wires  in  a  bundle  should  be  separated  by  at  least  one splice length.  This may require the use of the pre-made splice  segments  (Figure  9-10)  or  locally  manufactured jumper   wires   made   from   the   kit   primary   wire   stock spliced into the existing aircraft wiring.  Figures 9-4, 9-5, and 9-6 illustrate the technique for the splicing of 125°C or above rated wires of the sizes indicated.  Figures 9-7, 9-8,  and  9-9  illustrate  the  technique  for  splicing  wires rated   at   105oC   or   below   for   the   wire   size   indicated. Figure   9-10   illustrates   the   use   of   the   premade   wire repair   segments   on   primary   wires   rated   at   125°C   or above.      Adherence   to   these   techniques   results   in   a permanent, environmentally sealed primary wire splice.
