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   CONTROL MODULE   (EECM).   (cont.) (b)   Move   MASTER   SWITCH   to RUN  position.  All  lights  shouId  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  Iights  will  come  on  and  then STARTER   and   IGNITION   lights   will   go   off.   The FUEL  light  should  remain  on.  This  should  happen between 1965 and 2059 Hz. (d)   Increase   function   generator frequency   slowly   until   READY   TO   LOAD   light comes   on   and   FUEL   light   should   remain   on. This should happen between 3287 and 3421 Hz. (e)   Move CONTACTOR    switch momentarily to the CLOSED position. CONTACT- OR ENABLE light should come on. (f) Move OVERLOAD switch to ON   position.   The   OVERLOAD   light   should   come on and all other lights should go off. (g)   Move   OVERLOAD   switch   to OFF   position. The  OVER  LOAD  light  should remain on. (h)   Move   MASTER   SWITCH   to OFF  position.  All  lights  should  go  off. (i)   Any   discrepancy   noted   during the   above   procedure, Refer   to   Table   2-4,   Mal- function   8. (16)   Generator   undervoltage   fauIt   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. 10-14.2 Change 1 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 timeout. During   frequency   increase,   IGNITION and  FUEL  lights  will  come  on  and  then  STARTER and   IGNITION   lights   will   go   off.   The   FUEL   light should   remain   on.   This   should   happen   between 1965 and 2059 Hz. (d)   Increase   function   generator frequency   slowly   until   READY   TO   LOAD   light comes  on  and  FUEL  light  should  remain  on.  This shouId happen between 3287 to 3421 Hz. (e)   Move CONTACTOR    switch momentarily   to   the   CLOSED   position   CONTACT- OR   ENABLE   light   should   come   on. (f)   Move   UNDERVOLT   switch   to ON   position. The   UNDERVOLT   light   should come on and all other lights should go off. (g)   Move   UNDERVOLT   switch   to OFF   position. The    UNDERVOLT    light    should remain on. (h)   Move   MASTER   SWITCH   to OFF  position.  All  lights  should  go  off. (i)   Any   discrepancy   noted   during the  above  procedure. Refer   to   Table   2-4,   Mal- function   8. (17)   Fuel   pump   control   test. (a)   Adjust   function   generator   to   a frequency   between   0   and   200   Hz   and   adjust millivolt   power   source   to   .96   to   1.20   millivolts (K-type   thermocouple   equivalent   output).   Connect Oscilloscope   to   EECM   test   fixture   (pump   output terminal  Fig  10-1). (b)   Move   MASTER   SWITCH   to RUN  position.  All  lights  should  be  off. NOTE Read steps (c) and (d) completely before performing steps (c) and (d).
