TM 9-2350-261-34 INTRODUCTION HOW TO USE TROUBLESHOOTING 0005 00 PURPOSE The purpose of direct and general support maintenance level troubleshooting is to diagnose carrier problems which are reported to direct and general support maintenance. Troubleshooting tasks in this manual are common to all M113A2 FOV carriers except where indicated. You should not begin direct and general support maintenance troubleshooting until all operator and unit troubleshooting has been completed. You will perform four actions in direct and general support maintenance troubleshooting: (1) Before starting a troubleshooting task, verify that reported problem is present in carrier. (2) After verifying the symptom, find the part that is causing problem. (3) Replace or adjust that part. (4) Check to make sure problem no longer exists, and that there are no other problems. DEFINITIONS AND DESCRIPTIONS OF TROUBLESHOOTING PARTS Troubleshooting tasks always have a beginning and an end. You will use task steps, test procedures, indexes, maintenance tasks, and other technical manuals to troubleshoot. Troubleshooting uses the following terms that are not used in other kinds of tasks: 1. FAULT: The part that is not operating correctly and is causing the problem. 2. SYMPTOM: The problem reported by unit maintenance. 3. VERIFY NO FAULTS FOUND : After you have completed the corrective action, you must verify that no faults exist. If the fault condition still exists, then the fault is not fixed or there is another fault. If this happens, start at the beginning of the troubleshooting procedure until you find and correct all faults. Always operate the system an d/o r carrier to m ake sure t hat yo u have corrected the rep orted problem. If tro ublesh ooting d oes not identify a f ault y part, th e carrier is defective beyond the level of direct and general support maintenance. 0005 00-1
