TM 1-1520-240-BD application  of  this  material  is  necessary  if  the  desired wire or cable diagnostic test capability is to be achieved. (c) Procedures. The following procedures    is    to    be    followed    when    using    the    test equipment kit for electrical wiring system diagnostic test, troubleshooting, or verifying repairs: • Perform necessary steps to make aircraft safe, such as  making  sure  all  electrical  power  is  disconnected and  all  systems  are  deactivated.    Disconnect  the aircraft's battery. • Review DA  Form  2404 and apply this information to the aircraft serviceability tables. • Establish cable or wire repair sequence, starting with the  most  essential  requirement  and  proceeding  to non-essential, as time permits. • Determine    test    required    (continuity    with    DMM; location and type o fault with TDR). • Select proper adaptors from applicable charts. • Perform     necessary     test     using     DMM     or     TDR operating instructions. • Repair fault using the connector repair kit or the wire repair kit. • Retest  to  determine  effectiveness  of  repair.    Take TDR  readings  of  co-axial  cable  repairs  for  aircraft logs. • Return  all  contents  of  the  test  equipment  kit  to  the proper storage compartment.  Inventory kit content, account for all components, and prevent FOD. • After     completing     all     repairs     and     verifying     kit contents, perform standard check-out of aircraft and systems (powered). (2)  Connector Repair Kit. (a) Mission And Major Components. The   connector   repair   kit   is   used   to   repair   damaged wiring connector pins and sockets.  The kit contains the necessary tools to remove or insert connector pins and 94  sockets,  strip  wiring,  and  crimp  wires  to  connector pins and sockets.  The tools and their intended use are: • Insertion    and    Removal    Tools.        Insertion    and removal tools are supplied for use with front or rear release connector pins or sockets.  Selection charts and  tool  instruction  sheets  are  provided  to  aid  in selection   and   use   of   the   proper   connector   repair tool. • Wire  and  Cable  Strippers.    Strippers  are  provided for  wires  and  co-axial  cables.    Stripper  blades  are provided   for   the   most   common   aircraft   electrical wiring  insulation  materials.    Instructions  for  blade selection and stripper operations are supplied. • Connector   Pin   And   Socket   CrimpTools.      The   kit contains crimping tools, dies, and locating turrets for crimping    connector    pins    and    sockets    to    wire. Selection  charts  and  the  tool  instruction  sheets  are supplied  to  aid  in  selection  and  use  of  the  proper tools, dies, and turrets. (b) Use.        Prior     to     using     the     kits' contents,  a  working  knowledge  of  the  tool  instructions, tool   application   charts,   and   tool   selection   charts   is required.          The     software     package     duplicates     the environmentally   protected   software   within   the   kit   and provides  instructions  for  the  use  of  the  tools  and  tool selection charts.  Proficiency in the use and application of  this  material  is  necessary  if  the  desired  connector repair capability is to be achieved. (c) Procedure. Follow these procedures when using the connector repair kit: • Perform necessary steps to make aircraft safe such as  making  sure  all  electrical  power  is  disconnected and  all  systems  are  deactivated.    Disconnect  the aircraft's battery. • Review DA Form 2404 and apply the information to the aircraft serviceability tables. • Establish  connector  repair  sequence, starting with the  most  essential  requirement  and  proceeding  to nonessential, as time permits. • Perform   diagnostic   and   troubleshooting   tests   as applicable per paragraph 9-7b(1). 9-4
