I have been working to resolve this problem for a while and ... *%& ... I haven't gotten it fixed yet.
When I start the machine, the ball lifter works; however, it lifts multiple balls. It lifts two and tries to lift a third but there is no room in the alley and it stops. If these ball are put into play, no other balls are lifted. I have cleaned and checked the switch under the where the balls rest before being shot. I have checked the switch in the gate at the top of the alley. I have checked the switches under the ramp (balls 1-8) and the switch under the lifter where the balls rest before being lifted.
Here is the clue that has had me scratching my head: If I take three balls out, it will lift one ball. Then if I drop a ball into the ball re-shoot hole, it will lift one ball. Drop another..and it lifts another. Drop two and it will lift two.
I know that there are a dozen jokes about balls in this somewhere.
I need some suggestions to get this game playable again. Thank you.
