**UPDATE**
So after messing with the power supply I realized I was reading the power out voltage wrong. I am getting +5 and -12 out to the Ni-Wumpf board. I started over only plugging in one display at a time, etc and now when I power on the game I get all displays working and it will display credits. All of the drop targets pop up on the table but the ball kick, flippers, chimes are not working. I took the playfield art off and most of the rings but the leaf switches to the drop targets, etc do keep score. Any ideas on where to start the diagnostic on those? All fuses including the solenoid fuse are working.
