Stall warning switch

[kota]

My stall warning was not working, so I started at the switch. Nothing wrong with switch.
But found a wire behind panel that came loose. now I have a nice brite flashing light with a buzzer.
Works great on the ground. I have flown slow flight to 60mph did a stall and the light will not come on. I have adjusted the wing switch
to the highest position possible and It will still not come on in flight.
Any ideas out there??
