TM 5-6115-593-12 TO 35C2-3-463-1 Section XXII.  MAINTENANCE OF INTERCONNECTING ELECTRICAL WIRING HARNESS 4-57. GENERAL.    This  section  contains  information on    interconnecting    wiring    harnesses    of    the    engine generator  and  chassis.    The  wiring  harnesses  provide electrical  interconnection  between  major  assemblies  of the generator set. 4-58. TEST    AND    REPLACEMENT.        Proceed    as follows: WARNING Set  MAINTENANCE  LOCKOUT  switch  to LOCKOUT.      Disconnect   negative   cable from  batteries.    Remove  external  power by   opening   CB101   (120V   RECEPTACLE BREAKER).    Load  terminals  of  generator set   circuit   breaker   (CB2)   may   still   be energized with bus voltage. a. Test.        Perform    continuity    check,    using ohmmeter between connecting points in the wiring    harness.    Check    for    short    circuits between     connector     pins     of     the     same receptacle or terminal board. b. Repair. (1) If a broken wire is accessible remove sufficient  insulation  from  each  side  of  the break   to   allow   a   good   connection   of   the bared    ends    by    twisting    them    together. Solder     the     connection     and     wrap     with electrical tape. (2) If a wire is broken from a terminal lug, replace  the  lug.    If  a  wire  is  broken from a connector, resolder and reassemble. WARNING Under no condition leave the bare connection exposed. (3) If  a  break  in  the  wire  is  inaccessible within  the  wiring  harness,  disconnect it  at  both  ends  and  tape  both  ends. Lace  a  new  lead  of  the  same  gauge and    insulation    outside    the    harness and connect it to the proper terminals or pins.  Properly tag both ends of all replacement wires. Section XXIII.  MAINTENANCE OF GENERATOR AND RECONNECTION ASSEMBLY 4-59. GENERAL.      The   generator   (figure   4-36)   is   a synchronous,  brushless  device  with  an  integral  exciter. It is directly driven from the engine shaft through a disc coupling to provide line voltages at any load between no load and rated load.  The reconnection assembly allows reconnection   of   generator   windings   to   give   specified output    voltage    of    120/208    volts    or    240/416    volts operation. 4-60. RECONNECTION   BOARD   AND   BUSS.   (See figure  4-36.)  Inspect  for  cracks,  breaks,  corrosion,  and loose mounting. If replacement is required, refer to next higher level of maintenance. 4-61. GENERATOR.  Inspect for excessive heat during  normal  operation,  by  checking  for  peeling  paint, excessive  noise,  smoke,  and  abnormal  odors.  Refer  to next higher level of maintenance if overheating exists. 4-62. BEARING.    Inspect  the  generator  bearing  for signs of wear by checking for excessive unusual noise, smoke, and abnormal odors.  If replacement is required, refer to higher level maintenance. 4-63. DRIVE  PLATE  ASSEMBLY.    Inspect  the  drive plate assembly for distortion, excessive wear, and loose mounting.    If  replacement  is  required,  refer  to  higher level maintenance. 4-95
