Speaking of EGT sensors, where would be the best place to put them on = a=20 turbo engine?

= Tracy=20 and others,

I had a problem with the #2 EGT going erratically up t= o=20 over 2K. I couldn't
find anything wrong with the probe, so I sen= t the=20 EM-2 to Tracy for
evaluation. He didn't find anything wrong with= the=20 EM-2 so back to the
drawing board!

I got my hangar mate to come= out=20 and give me an assist. We discovered that
if I moved the probe b= ack=20 and forth along the exhaust manifold, the output
of the probe would ch= ange=20 up to into the 40s milivolt. At first I thought
that I was someh= ow=20 getting voltage onto the exhaust manifold and it was
being picked up b= y the=20 probe.

Turns out that the probe connects to the thermocouple wire = with=20 two ring
connectors and the edges of the ring connectors were cutting = thru=20 the
insulation of the adjacent wire causing a short.

Tracy has = sent=20 the EM-2 back and now I need to figure a way to connect the
wires with= out=20 causing a short and so that it doesn't cause an error in=20 the
output.

Anyone have a suggestion about how to do=20 that??
