TM 5-3810-207-20/TO 36C23-3-37-12 (e) The  carrier  engine  is  equipped  with special   suppressed   spark   plugs   to suppress radio interference. (f) Instructions  for  replacement  of  the above  suppression  components  will be found in the applicable maintenance section of this manual. (2) Shielded cables. (a) The   carrier   generator   is   equipped with a shielded cable connecting the generator to the generator regulator. (b) The ignition cables that connect the spark  plugs  to  the  distributor  are  of the shielded type. Note. Do not pull on the cable or twist the braided  shielding.    Gently  work  the cable  from  side  to  side  and  free  the rubber seal.  Do not use sharp metal tools to install the rubber seal. 67.  Replacement of Suppression Components a. General. For replacement, suppression components   must   be   identical   to   the   original   part. Capacitors  must  be  the  same  size  and  have  the  same microfarad    and    voltage    rating    as    the    part    being replaced.    Special  care  must  be  taken  to  be  certain there is a good metal-to-metal contact with washers and bonding straps. b. Primary Suppression Components. (1) Ground straps.  Replace ground straps as illustrated on figure 5. (2) Suppression cover.    Replace  suppression cover as illustrated on figure 5. (3) Suppression receptacle. Replace suppression   receptacle   as   illustrated   on figure 5. c. Secondary  Suppression  Components (Crane). (1) Tooth-type lockwashers. (a) Replace    the    generator    tooth-type lockwashers (par.  72). (b) Replace     the     generator     regulator tooth-type lockwashers (par.  73). (c) Replace   the   distributor   tooth-type lockwashers (par.  74). (d) Replace  starter  and  solenoid  tooth- type lockwashers (pars.  77 and 78). (e) Replace the spark plugs (par.  76). (2) Shielded cables. (a) Replace  the  shielded  generator-to- generator regulator cable (pars.  72 and 73). (b) Replace the spark plug-to-distributor ignition cables (par.  76). d. Secondary Suppression Components (Carrier). (1) Tooth-type lockwashers. (a) Replace    the    generator    tooth-type lockwashers (par.  206). (b) Replace     the     generator     regulator tooth-type lockwashers (par.  208). (c) Replace   the   distributor   tooth-type lockwashers (par.  200). (d) Replace   the   starter   and   solenoid tooth  type  lockwashers  (pars.    203 and 204). (e) Replace the spark plugs (par.  202). (2) Shielded cables. (a) Replace  the  shielded  generator-to- generator     regulator     cable     (pars. 206 and 208). (b) Replace the spark plug-to-distributor ignition cables (par.  202). 68.      Testing   or   Radio   Interference   Suppression Components Test   the   capacitors   for   leaks   and   shorts   on   a capacitor  tester;  replace  defective  capacitors.    If  test equipment is not available and interference is indicated, isolate    the    cause    of    interference    by    trial-and-error method   of   replacing   each   capacitor   in   turn   until   the cause of interference is located and eliminated. 27
