Good luck with the dating, guess you were too occupied to answer my legal question :>)

I don't recall the previous EM2 suggestions but the tests are pretty simple, take only a minute or two and are usually definitive.
 
Try this:
 
With EM2 turned on, Measure the voltage at the sensor.  It should read about 2 volts at room temp.  If it is zero, you have an open connection to the EM2 or it is wired to the wrong pin or is the wire is shorted to ground (check with ohm meter).  If it reads about 5 volts, you have an open ground on the sensor (use that meter again) or a bad sensor.
 
If it does read about 2 volts and you still read 0, the EM2 is way out of calibration or is broken.

focused on my project as of late :-).  However, I have been back in the
hangar again now that my schedule has somewhat normalized.

I am having a problem, still, with my EM2.  The coolant temp and  oil temp
is reading "zero" (0).  I have checked the wires, re-wired the connections
and tried them on different sensors all to no avail.

This is really slowing down my engine development as, even though I can run
my engine, I hesitate running it for more than a couple of minutes without
this info for fear of over heating and causing harm.  I did buy an external
infrared gage to help, but still does not solve the problem.

I did mess with the calibration feature on coolant temp with now success.  I
have now re-set those variables to the numbers listed in the RWS EM2 manual.
I still have the zero's staring at me stubbornly.  There is not change from
zero regardless of the temps.

The suggestions that were made this summer were tried, but feel free to
RE-suggest to bring my memory back on-line.  I am becoming annoyed.....both
at the systems and my inability to figure it out. Y'all's help is
appreciated.

All the best,

Chris
