Best to start at the source and it's Possibly a lose connection on the breakout board anyway. Trace the wire back into the control box and see if you can identify the input it's using on the breakout board.
Then to test the breakout board hasn't fried it's input take a short wire and place between the (+) input and Gnd(-) watching the digitise input in mach to see if toggles on/off.

If it does then you know it's either the wire or puck. If not then you probably have a blown Input on the Breakout board.
