  No time for temperature measurement instrumentation theory 101 today so
I'll just give you the typical values for the coolant (and oil) temperature
channels.  Just plug these values in and see what happens.

  Scale factor -  2.151
  Low end offset  - 100
  Sensor offset -  390
  Low alarm limit  - 0  (or whatever you want)
  High alarm limit -   210 for 2 & 3 gen, 225 for Renesis

  If still no joy, disconnect the temp sensor and check reading for change.
  If no change,  disconnect wire for coolant temp at EM2 connector and check
for change

  If still no change, EM2 is bad (not likely since similar channels on unit
are working)

  Most likely problem is a short to ground on the sensor line.

  Hope this helps.

    Shocking....Chris is asking another question about the EM2.  Hey, me
asking
    questions means I am out there trying to make progress......not that I
am
    defensive or anything <g>

    Anyway, since my "buttons" issue the Coolant Temperature on the main
screen
    has been showing "0".    The oil temp is working ok.  I figured that I
must
    have inadvertently set it to 0 when I was having my button problem.  I
    figured now that the buttons are working properly I could just go and
    calibrate it.  Figured a good starting point would be to use the cold
oil
    temp as a guide.  However, when I try to calibrate it, it will not
change
    from zero.  I thought that maybe there was not % change from zero and I
    tried changing other calibration modes but nothing I have currently
tried
    has changed it from zero.  I admit to very little current understanding
of
    the calibration feature at this time (even though  I really like that it
is
    included in the EM2....I like options even though they can be a pain
    sometimes).

    Any direction on how to get this off of zero would be helpful as I am
    hesitant to start the dang thing 'till I can know how hot the coolant
    is....I know I can get some idea from the oil, but still.

    David Staten will probable be much better at figuring this out, but we
have
    not been able to meet up for actual progress in the last few days.  TIA.

    All the best,

    Chris
