GENERAL. a. This  section  provides  information  for  identifying  and  correcting  malfunctions  that  may  develop  while  operating  or maintaining the Diesel Engine Assembly, Hatz 2 G 40. b. The Quick Guide to Troubleshooting (para 3-2) lists common malfunctions of the diesel engine or its components and  refers  you  to  the  appropriate  paragraph  in  the  Troubleshooting  Chart  (para  3-3).    You  should  perform  the tests/inspections and corrective actions in the order listed in the chart. c. If  you  are  unsure  of  the  location  of  an  item  mentioned  in  troubleshooting,  refer  to  paragraph  1-12  or  to  the maintenance task where the item is replaced. d. Before performing  troubleshooting,  read  and  follow  all  safety  instructions  listed  in  the  warning  summary  at  the beginning of this manual. e. This  section  cannot  list  all  malfunctions  that  may  occur,  or  all  tests  or  inspections  and  corrective  actions.    If  a malfunction is not listed or is not corrected by the corrective action listed, notify your supervisor. f. When troubleshooting a malfunction:    In the Quick Guide to Troubleshooting, locate the symptom or symptoms that best describe the malfunction.    Turn   to   the   subparagraph   in   the   Troubleshooting   Chart   where   the   troubleshooting   procedures   for   the malfunction in question are described.    Perform each step in the order listed until the malfunction is corrected.  DO NOT perform any maintenance task unless the troubleshooting procedure tells you to do so. g. When  troubleshooting  any  electrical  system  or  component,  exercise  extreme  care  in  order  to  prevent  electric shock. WARNING · To prevent injury due to electric shock throughout troubleshooting of the  electrical system or electrical  components,  be  certain  MASTER  switch  is  turned  off  between  every  step  unless otherwise directed. · To prevent injury due to electric shock, remove all jewelry and metal objects when working on the electrical system. h. The  multimeter  is  used  throughout  troubleshooting  of  the  electrical  system.    When  using  the  multimeter,  make sure it is used with a probe kit. i. When  performing  a  continuity  check,  connect  the  meter  probes  to  both  terminals  of  the  circuit  you  are  testing. Read  the  meter  and  interpret  the  results.    If  the  needle  swings  to  near  0  on  the  top  scale,  the  circuit  has continuity.    If  the  needle  does  not  move,  the  circuit  is  open.    If  the  needle  jumps  or  flickers,  there  is  a  loose connection. 3-1
