I have been working on a ball stepper unit for a Gottlieb 2001. I have replaced one coil and the springs. The unit will reset but sticks on one ball, number varies or it moves two balls ie: 1-3. I am stumped. Anyone have an idea for me to try? Thanks
What happens when you manually advance the ball stepper unit? When you advance the ball stepper, does it rotate smoothy and "click" into each position? Is there a lot of grease on the wiper blades, hub or disc gears?
