I’m working on a Gottlieb 300 for a friend. It had sat for years and had plenty of issues, as you can imagine.
I’ve got it working nearly perfectly, except about once a game it doesn’t advance the player or ball count. I’ve cleaned the stepper unit.
The owner is happy with the way it is, but I’d prefer to have it working perfectly before he takes it.
What exactly sends the signal to the stepper unit? Is it the score motor? If so, does anyone know what switch?
Thanks in advance.
