ARMY TM  5-6115-612-34 MARINE CORPS TM 6115-34/8 AIR FORCE TO 35C2-3-471-2 NAVY AG-320B0-MME-000 10-2.   ENGINE ELECTRONIC MODULE   (EECM).   (cont.) (h)   Any   discrepancy CONTROL noted   during above   procedure   indicates   a   failure   in   EECM contractor enable circuit. Refer to Table 2-4, Malfunction 9, step 2. (11)   Overspeed   test. (a)   Adjust   function   generator   to   a frequency   between   0   and   200   Hz   and   adjust millivolt  source  to  .96  to  1.20  millivolts. (b)   Move   MASTER   SWITCH   to RUN  position.  All  lights  should  be  off. NOTE Read   step   (c)   completely   before   per- forming  step  (c). (c)   Move   MASTER   SWITCH   to START   position. The   STARTER   light   should come   on. Quickly   increase   function   generator frequency   until   READY   TO   LOAD   light   comes on.  This  should  happen  between  3287  and  3421 Hz. The   FUEL   light   should   be   on   and   the STARTER  light  should  have  gone  off. (d)   Slowly   increase   function   genera- tor     frequency     until     engine     OVERSPEED     light comes   on. This   should   happen   between   3615 and  3763  Hz.  All  other  lights  should  be  off. (e) OFF    position. off. (f) Move   MASTER   SWITCH   to OVERSPEED   light   should   go   to Any   discrepancy   noted   during the   above   procedure   indicates   a   failure   in   the EECM   overspeed   circuit.   Refer   to   Table   2-4, Malfunction   5. (12)   Low   oil   test. (a)   Adjust   function   generator   to   a frequency   between   0   and   200   Hz   and   adjust millivolt  source  to  .96  to  1.20  millivolts. 10-14 Change  1 NOTE EECM   electronics   requires   a   frequency below 200 Hz. (b)   Move   MASTER   SWITCH   to RUN  position.  All  lights  should  be  off. NOTE Read   step   (c)   completely   before   per- forming  step  (c). (c)   Move   MASTER   SWITCH   to START    position. The   STARTER   light   should come   on. Quickly   increase   function   generator to  a  frequency  between  2900  and  3200  Hz  before EECM    timeout. During   frequency   increase IGNITION  and  FUEL  lights  will  come  on  and  then STARTER   and   IGNITION   lights   will   go   off. (This   should   happen   between   1965   and   2059 Hz).  The  FUEL  light  should  remain  on. (d)   Continue   to   increase   function generator   frequency   slowly   until   READY   TO LOAD   light   comes   on. This   should   happen between 3287 to 3421 Hz. (e)   Move   LOW   OIL   switch   to   ON position. LOW   OIL   PRESSURE   light   should come  on.  Start  timing  device.  Stop  timing  device when   all   other   lights   go   off.   This   should   happen between 0.5 and 2.0 seconds. (f)   Move   LOW   OIL   switch   to   OFF position.   The   LOW   OIL   PRESSURE   light   should stay on. (g)   Move   MASTER   SWITCH   to OFF  position.  All  lights  should  be  off. (h)   Any   discrepancy   noted   during the   above   procedure   indicates   a   failure   in   the EECM   low   oil   pressure   circuit.   Refer   to   Table 2-4,  Malfunction  7. (13)   Generator   over   temperature   fault   test. (a)   Adjust   function   generator   to   a frequency   between   0   and   200   Hz   and   adjust millivolt  source  to  .96  to  1.20  millivolts.
