I was flying back to Sweden from the UK yesterday. Went down from FL190 over the North Sea through a layer of icing in IMC. It was not much, not the complete windscreen and just some mm on the wing. The ice went away and then suddenly out of the cloud and when the ice melted below 9000 ft and speed still was about 177 kt, the stall warning started slowly to scream. The wings had all the ice melted away and after 5-10 minutes it began to scream. I had to take out the circuit breaker. After landing and in warm temperatures, it was still screaming if I enabled the circuit breaker again. I experienced a problem with the stall warning earlier and I think that had to do with why I couldn't turn off the Avionik Master last year. Suddenly the Avionik Master started to work after I have exercised the stall warning switch, but I was not able to prove it since it had gone then. My Mooney M20K 252 has no TKS so I think it is not preheated. Does anyone have experience of this?

Hi Mooniacs, We have a problem with our 2005 Mooney Ovation 2GX - suddendly doing flare the engine instrument switch pop out - we thought it was the tachometer, but when disconnected the problem was still present. After some research, we figured out that it's the lift detector (stall switch) that cause the problem. When we have power on, and flick the switch shortly, then the fuse "engine instruments" pop out. Some times you can activate the lift detector 2 seconds and hear the stall warning on for quite som time, other times the fuse instantly pop just the moment you flick the lift detector. The lift detector works (it activate the stall warning), but it pop the engine instrument fuse. Other Mooniacs ever had same issue? And have idea's for possible solutions other than buy a new expensive part without knowing for sure that's the issue. Best Regards from Denmark.
