MIR2018 Posted March 23, 2019 Report Share Posted March 23, 2019 (edited) My CHT gauge indicates 100 degrees with the engine cold. Tapping it doesn't solve the issue (in case you were thinking to try that). I'm assuming the gauge is just bad. Anyone know where I can get a replacement? And, is it easily swapped out? Also the gauge reads close to 400 most of the time in flight... I'm thinking I can assume that's really 300 ? I know its only one cylinder anywayz, but just wondering what's the consensus... Oh, and if its not an exact replacement what if anything needs to be done to make it legal? Edit: I'm not in the market for a JPI or any kind of upgrade right now...

7.Mooney.Driver.0 Posted March 23, 2019 Report Share Posted March 23, 2019 Disconnect the probe and check to see if it goes down to zero, check the wiring too. It could be a bad probe or wiring. Worth a shot before buying a new gauge. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Disconnect it, but about the 400... most likely that is the CHT you are getting... see previous discussion about CHT.Sent from my iPhone using Tapatalk Pro 1 Quote Link to comment Share on other sites More sharing options...
carusoam Posted March 23, 2019 Report Share Posted March 23, 2019 Can you put the TC in hot water? Boiling water, in case you don’t have a second thermometer... 400°F is typical of leaky dog house boxes and crummy seals around the O360... PP thoughts only...
