TM 10-3930-669-34 2-8.  TROUBLESHOOTING INSTRUCTIONS. NOTE The   troubleshooting   makes   use   of   the   Simplified   Test   Equipment   for   Internal Combustion  Engines-Reprogrammable  (STE/ICE-R)  and  conventional  methods  for testing and fault isolation. a. Simplified Test  Equipment  for  Internal  Combustion  Engines  Reprogrammable  (STE/ICE-R).    The  forklift  is equipped   with   several   STE/ICE-R   sensors   that   are   used   to   support   troubleshooting   procedures.      STE/ICE-R   tests, employing these sensors, are incorporated into the standard troubleshooting test to aid in fault isolation.  The STE/ICE-R acts  as  a  conventional  digital  multimeter  to  measure  voltage,  current,  and  resistance.    It  can  also  measure  pressure, speed, compression unbalance, engine power, and some specialized battery and starter evaluations.  The STE/ICE-R is powered by the forklift battery using an electrical harness called the Diagnostic Connector Assembly (DCA).  The complete system  includes  a  test  meter  (VTM),  cables,  transit  case,  and  technical  publications.    The  STE/ICE-R  can  make  TK measurements while connected to the DCA.  STE/ICE-R tests are referenced. b. General Electrical Troubleshooting Procedures. WARNING Remove  rings,  bracelets,  wristwatches,  neck  chains,  etc.,  before  working  on  any vehicle.  Jewelry can catch on equipment and cause injury, or may short across an electrical circuit and cause severe burns or electrical shock. CAUTION Use proper sized test leads when checking for resistance, continuity, or voltage at connectors or damage to equipment can result. NOTE • Multimeter  leads  must  remain  in  contact  with  the  circuit  being  tested  for  a minimum of three seconds to obtain a reading. • If  your  multimeter  does  not  operate  in  the  way  described  in  the  following steps, learn how it operates before performing troubleshooting. • The   piece   of   electrical   test   equipment   used   will   be   referred   to   as   the "multimeter."   The   multimeter's   red   test   lead   will   be   referred   to   as   the "positive (+) multimeter lead." The multimeter's black test lead will be referred to as the "negative (-) multimeter lead." 2-6
