TM 9-254 Section IV.  TROUBLESHOOTING TECHNIQUES 7-11. Basic Troubleshooting Procedure. a. Trouble  Symptom.    The  basic  troubleshooting  procedure  is  an  organized  plan  of  action  to  help  you  repair faulty  electronic  equipment  rapidly  and  reliably.    This  systematic  and  logical  troubleshooting  procedure  starts  with  the trouble  symptom.    The  trouble  symptom  lets  you  know  that  something  is  wrong  with  the  equipment.    So,  you  have  to analyze the trouble symptom as it affects the operation of the equipment.  The trouble symptom provides clues that show you where to look for the trouble. b. Sectionalize.    Once  you  have  recognized  the  trouble  symptom,  the  next  step  is  to  sectionalize  the  trouble. Each piece of equipment is divided into a few basic sections.  But to trace the trouble to a particular section, you must first analyze and evaluate the trouble symptom to decide which section is giving trouble. c. Localize.    After  you  have  found  which  section  of  the  equipment  is  at  fault,  the  next  step  is  to  localize  the trouble to a particular circuit or stage. d. Isolate.  After localizing, the next step is to isolate the faulty component either by making a visual inspection or by taking voltage and resistance measurements. In this manner, you pinpoint the trouble to a bad component in a single stage. e. Repair.  Correct the trouble by repairing or replacing components in the stage. f. Check  Operation.  After  repairing  the  trouble,  check  the  operation  of  the  equipment  to  make  sure  that  it  is functioning properly. 7-12. Troubleshooting with the Technical Manual. a. General.  This section explains how to use the technical manual (TM) when troubleshooting and performing the various procedures listed in the manual. b. Selecting the Proper TM.  The Direct Support and General Support Maintenance Manual, TM 9-1240-XXX-34 series, should be selected when performing troubleshooting procedures.  This manual is divided into two volumes for this purpose. (1) Volume I, contains troubleshooting procedures. (2) Volume II, contains maintenance procedures. c. How to Troubleshoot (fig. 7-20).  The following steps explain how to troubleshoot using the TM 9-1240-XXX- 34 series TM. (1) Do a visual check and list any faults on DA Form 2404 before making repairs. See Volume II, Chapter 3 for what to check for. (2) If you see any faults that may affect the checkout procedure, fix them now. This does not mean small things like painting scratches. 7-22
