JimB Posted June 17, 2021 Report Posted June 17, 2021 I have a 69 F with the pedestal throttle/prop/mixture controls. Anyone have the PN for the gear warning microswitch in there? It has stopped working. The overhead buzzer is good and I can hear it clicking lightly when I bring back the throttle but no warning. Possible it is wiring but before before I take apart the pedestal, I'd like to have one of these switches in hand. The AMM electrical diagrams show it as 20WM03A but the list in the back doesn't list it unless I am missing something. Thanks Quote
RobertGary1 Posted June 17, 2021 Report Posted June 17, 2021 (edited) Are you sure it’s contacting? If the friction is loose it will miss the switch. I’d you remove the plastic tops you can remove the cover snd watch it Edited June 17, 2021 by RobertGary1 Quote

Its a little hard to see exactly what it is doing until I take the covers off. Quote
carusoam Posted June 17, 2021 Report Posted June 17, 2021 If we are discussing the switch that rides on the throttle… It is easy enough to inspect…. (For young and thin people, it’s under the panel…) They sometimes get out of adjustment… There are pics around here somewhere for adjusting it… PP thoughts only, not a mechanic… Best regards, -a- Quote

Not the push pull style throttle. 1 Quote
