Hello everyone, I am new to working on pinball machines and have a pretty basic knowledge set. I am working on an Gottlieb Arena and the issue I am having is after the ball rolls over one of the top L-O-K lane the right flipper won't change the selected lane like it is supposed to. Is this a setting issue or should I be looking for a wiring problem? I can't identify any problems with the wiring but I am not too sure what I should be looking for. I appreciate any help! Thank you.
