i would try the doorknob or doorknobs if it has more then one , that is if your not too buried in the snow, and you do now have a fly tester , simple to use , remove these tubes , the horz out , the hv rect , the damper , one wire goes to the plate cap wire of the horz out and the other to the plate cap wire of the hv rect , before connecting the wires you turn it on , set it to shorts , adjust the needle to the iron core line on the meter , hook wires up to the plate cap wires without touching and you will get your results , the fly will probably sing too.
