I bought a used machine called "Seven League". I am completely new to these machines, so any help would be appreciated. Anyways, I figured out how to change the skill level, etc., but the reel stop buttons will not work at all. You pull the spin knob and after about 30 seconds the reels will stop on their own, but the reel stop buttons will not work. I unplugged and plugged back in all the wires from the buttons, but still the buttons do not work. Any help would be greatly appreciated.
