Skyview EGT jumpy readings then big red X

[mikehoover]

Out flying yesterday I noticed that my #2 cylinder EGT reading started jumping around, going very high, then red X for a moment then back to normal - repeat, repeat... The erratic behavior is intermittent and when it "settles down" the readings seem normal and in line with the other cylinders. Any ideas for the cause? Thanks!

Coincidentally, I had a similar problem (red "X") on the #2 CHT last week.  The "Sensor Data" screen for the faulty channel showed erratically jumping data and "NaN" (not a number) for the reading.

Mike H. at Dynon tech support suggested checking the crimps at the probe-end of the 25-pin EMS harness.  Sure enough, re-crimping the #2 CHT probe wires fixed the problem.

YMMV but I bet that's it

Thanks for the suggestion Joe. I re-crimped the connectors yesterday and went flying. Seems to have corrected the problem.
