You might be experiencing a ground problem rather then a noise voltage. A single
point ground is recommended. CHT's and EGT's output millivolts which make
them sensitive to ground current loops and noise.
You might also want to do an oil bath calibration of the CHT probes to verify that
the displayed reading is reasonably accurate. You can pick up a wireless
digital thermometer for less than $30 at most Ace hardware stores. Running the
test with probes floating and grounded may give significantly different results.
Good luck.
