Quoted from big-c66:... when u hit the start button there’s a wheel looking mechanism that just keeps turning n turning it says on the inside it’s a cam all I done is fixed the power cord dropped a quarter in and all the scores turned n reset to zero n the cam wheel just turns n turns any idea what is going on n how to start fixing it thanks
That "cam wheel" is the start motor and one of the switches within a circuit that provides power to it is probably staying closed when it shouldn't be. Per the prior post, you need to get yourself a schematic copy and manually check all the switches that should normally be open in the applicable circuits. Many times this is one of the score reel switches.
