One thing that I see wrong in your pics is that the flipper coil is installed incorrectly. The solder lugs should be by the coil stop. Also the EOS contacts look dirty. They can be cleaned up with some 400 grit sand paper. It's hard to see from the pics, but what is actually opening the EOS? It looks like the set screw is hitting it. There should be a small stud sticking up that activates the EOS. Also make sure the flipper is moving freely by moving it up and down by hand. I don't have access to my games at this time to verify your wiring. The fact that the upper flipper isn't working makes me wonder. The closing of the outer lower EOS switch should send power to the upper flipper. It should fire unless there's a separate issue with the upper flipper.

It really doesn't matter but all of the early Stern and Bally flippers I see have the coil mounted with the lugs by the coil stop. Yeah some will say it's bad because the the vibration of the plunger hitting the coil is too close to the diodes of the coil.

Have you made any progress?

I saw that. Just wondering if he replaced yet.

You can touch the wires together just to see if the flippers fire.
