CHT READING

[AMONTOYA]

Hello,
Installed in a 2015 Rotax 912 ULS with Skyview 10"T airplane with 130 hours without problem started to read on R CHT ascending up to maximum temp for 5 second and then comeback to normal range (same as L side) during low RPM operations (taxi and app).
Any suggestion?
Thank you.

Does it go up gradually? Or is it an instant change? If you had the signal wire shorting to ground, you'd have a spike that goes high. The 912 CHT is a probe that comes on the engine (and is not supplied by Dynon), so you'd want to source a replacement for that from a Rotax dealer. But first, I'd probably check the connections.
