I'm still missing the ball lift and the proper shooter gauge but while I wait for those parts, it's a great time to get started with the mechanics of the game! I don't have any schematics so diagnosing and tracing wires is going to be extremely difficult for me.
I kept the backglass off so that I can more easily watch and change out light bulbs as needed. After quite a bit of testing, I've got a list of issues to fix. The two most important ones would be the entire "Skill Point" system is not working at all. Also, the blocks 1-6 do not light up when the corrosponding bumper is tripped. I have no clue where to start on those two problems so I'm going to have to trace the wires and find out which relays go with those systems.
