a recent problem just popped up with my Nascar, if I shoot the ball up the truck ramp when the cars are not spinning the machine will fire the truck ramp coil to push the ball to the ramp and back to the flipper but if the cars are spinning and the ball gets passed them it just sits on the switch until the machine goes into ball search mode. the switch tests fine, its just weird that the machine doesn't read the ball when the cars are spinning only...any ideas?
