Hi Chris,
I will reply as I have a classic install but admit I won't be much help. I used
an engine monitor that went out of business, called Audio Flight Avionics. It
came with two threaded (5mm?) CHT probes that screwed into two holes already
tapped on the front left and right rear cylinders. I am 40 miles from my hanger
so I can't go out and look or take any measurements very soon. The 3/8" ring
terminal you mention is meant to go under on of the spark plugs on the same
cyclinder
most likely. Don't understand the 1/8" one though. I'd call Grand Rapids
for guidance unless someone here knows.
I remember having to move the EGT probes slightly away from the heads very
slightly,(again
can't measure today) in order to get away from the thick area of the
exhaust pipe. With that, coincidentally, I was about to broach the subject
of EGT here in a few days when I have gathered some data on my plane. It seems
two of my cylinders are hotter than they should be, but thats off the point for
now. Hope you can get the answers you want.
