We just got a Flipper Parade a week ago and I've worked out most of the scoring issues it was having except the right sling shot. It does not score 1 point when unlit but it scores 10 points when lit. The left sling functions properly. I can not see what controls it. The switches above the slings control the rotation of the slings being lit however when I trigger it only the wheel in the middle moves and the score motor moves. I can't find what switches them from 1 to 10 points. The pops were easy as they had their own solenoid under the playfield for it. If I had a schematic this might be easier lol.
Also, how do you tighten/adjust the number wheel. Ours is off and you get a gap between numbers most of the time. I don't see a set screw yet.
