2 EGT sensors out after Surefly installation
I've had my RV-9A for a little over a year. I had my first condition inspection done by an IA at a destination airport. I wasn't involved. I just trusted the IA and came back a couple days later when he was finished. This time I did an owner assist CI at my home airport with a friend who is an IA. When looking at the logbooks we noticed that the mags haven't been overhauled in almost 1,000 hrs. I decided to replace the left mag on my O-320 with a Surefly electronic ignition and then send out the R slick mag to get overhauled.
The installation went well and when the CI was complete everything looked good and the engine run-up and checks.
On my first flight I decided to go and do some touch and gos. There was no problem on the first time around. However as I took off after the first touch and go I noticed the #2 and #4 EGT readouts on the Dynon Skyview were bouncing all over the place. By the time I made it around to land (decided to do a full stop and take a look) I had a red X on the #2 and #4 readout.
I didn't see anything obvious when I looked at the EGT sensor connections but I decided to replace one of the connections just to see. It did not help. For some background I did need to replace both EGT sensors on the other side (#1 and #3).
What are the chances that both EGT sensors would go out at the same time and both on the same side? Could it have anything to do with the Surefly? It seems unlikely to me. Does anyone have any suggestions? I talked to Surefly they don't see how they could be related (I agree). Did we do something in the CI that may have caused it? If so what?
SO sorry on my original post I wrote CHT sensor. I was thinking EGT the whole time and just wrote the wrong thing
