John Fletcher Posted December 7, 2019 Report Posted December 7, 2019 (edited) I have a 1975 M-20F and have light problems. The warning light stays on except when gear is up. Actually the gear warning and gear down lights work at the same time. Both go on and off at the same time Anyone have an Idea. I cant find a wiring diagram for my Aircraft. The one I have is for a 1974. John Edited December 7, 2019 by John Fletcher
Prior owner Posted December 7, 2019 Report Posted December 7, 2019 I wish mine did that- it’s annoying to fly around with a red light on the panel! I have wondered whether Mooney changed this feature in the later year models...

It sounds like the normally open position is failed as that's the one that drives the light. IIRCSent from my Pixel 2 XL using Tapatalk

The big ugly light is big and ugly for a reason... It is hiding a mechanical iris in there... Twisting it opens and closes the iris... Give it a try... Just make sure you don’t close the green one completely... If airplane manufacturers wrote POHs back in the day... they would have covered how all the controls work... PP thoughts as usual...
