I had a CHT probe that wasn’t reading just —- Swapped it to another cylinder and it followed. I bought a new CHT probe from Steinair. Added some heat to the probe to ops check. It came up to 100+ degrees. Installed the prob. Turned on the avionics 45+ mins later and that probe was reading 300 degrees with a cold engine. Any ideas where I should start? Thanks in advance.
