I have had this problem for a long time, just taking one more try to resolve. Both CHT's bounce around a lot. When running relatively hot the readings bounce into the red zone and set off alarms. Both left and right CHTs bounce together. Looking at the wiring diagram it seems that the 5 volt supply is one common factor. Has this been seen as a problem with any other D-180 units? Suggestions?
