TM 3-4230-218-30&P MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION e. If  no  indication  (indicator  needle  has  not  moved  from  previous noted   position),   WATER  TEMP  gage  is  defective.  Replace  water temperature  gage  (refer  to  page  2-70). f. If  ice  is  not  available,  obtain  some  water  and  heat  to  boiling. g. Insert  bulb  in  boiling  water. h. After  several  minutes  observe  temperature  indication  of  100°C. i. If  no  indication,  WATER  TEMP  gage  is  defective.  Replace WATER  TEMP  gage  (refer  to  page  2-70). 15. OPEN MAG VALVE INDICATOR FLUCTUATES. NOTE This  indicator  operates  from  the  flame  intensity.  If  flame  is  steady  and  the indicator   is   fluctuating,   troubleshoot   as   follows: Step  1. Check  for  cracked,  burned,  or  broken  lamp  socket. If  lamp  socket  is  cracked,  burned,  or  broken,  replace  lamp  socket (refer  to  page  2-66). If  lamp  socket  is  not  defective,  proceed  to  step  2. Step  2. Check  for  defective  magnetic  valve. Refer  to  MALFUNCTION  4,  step  5. If  magnetic  valve  is  not  defective,  proceed  to  step  3. Step  3. Check  for  defective  engine  lighting  coil. Refer  to  MALFUNCTION  4,  step  2. Step  4. Check  for  malfunctioning  electronic  module. Start  the  decontaminating  unit  and  establish  water  pressure. Using a  multimeter  switched  to  the  +DC  volt  range,  verify  that  the  voltage across  terminals  12  and  7  of  the  control  panel  terminal  strip  is  not less  than  10  V-dc. If  required  voltage  is  not  present,   replace  electronic  control  module (refer  to  page  2-74). 2-11
