Hey guys another issue related to the gear. Gear warning horn isnt going off in my 77 PA28R-201. It used to, but just stopped recently. Micro switch is making contact in the quadrant, then there is the tube flasher and the horn itself.
So when I pull the throttle back in flight, the GEAR UNSAFE light comes on, but no 90HZ squeal from the horn.
Anyway I kind of what to assume the micro switch in the quadrant is probably not the problem since its making contact and has that audible "click" when you pull the throttle back. Should I suspect the tube flasher is bad? Thanks guys for all the help.

I have a feeling that this might be it.
