Hi - I am a newbie to this, so please bear with me. I recently purchased Williams Aces and Kings, and I can't figure out how to fix this.
I can't get the change relay (I think that's what needs to be fixed) to work. It generally always stays lit on the right "Increases Value when Lit." When the spinner turns, the right side value increases, but when you get in the hole, it doesn't give you the points.

However, the left side will give points, but I can't ever get the left side increase value to light up. It is supposed to change when you hit either of the top bumpers, or the top side bumpers. It just stays on right side. The change relay seems to work correctly, although one of the switches always sparks when the solenoid moves the plastic.

I could use any hints - in the meantime I'm watching how to read schematic videos... Thank you.

George
