Tracy and others,

I had a problem with the #2 EGT going erratically up to over 2K. I couldn't
find anything wrong with the probe, so I sent the EM-2 to Tracy for
evaluation. He didn't find anything wrong with the EM-2 so back to the
drawing board!

I got my hangar mate to come out and give me an assist. We discovered that
if I moved the probe back and forth along the exhaust manifold, the output
of the probe would change up to into the 40s milivolt. At first I thought
that I was somehow getting voltage onto the exhaust manifold and it was
being picked up by the probe.

Turns out that the probe connects to the thermocouple wire with two ring
connectors and the edges of the ring connectors were cutting thru the
insulation of the adjacent wire causing a short.

Tracy has sent the EM-2 back and now I need to figure a way to connect the
wires without causing a short and so that it doesn't cause an error in the
output.

Anyone have a suggestion about how to do that??
