I am working on the 75 Soccer and cannot get the player lights in the light box to alternate between Player 1 and Player 2. They stay on for both players all the time. I have looked at the ball stepper unit and looked at the cams and switch positions, they all seem to me okay but it is also hard to see some of the switches in the stacks. Can anyone show me the exact location or stack I should be looking at and concentrate on? I have the schematics but don't really know how to read them very well. Thank you in advance for the help.
