I don't have a schematic for Shaq attack, so my comments are based on other System 3 machines, and I'm also assuming you've wired things properly.

Gottlieb flippers are about as basic as it gets. They never stepped into the modern age of solid state flippers. That means that there are only a couple of ways to blow a flipper fuse when you flip. You can have a a bad diode, a bad coil, or a closed end of stroke switch. You're telling us that the coil is wired properly and tested good, as is the diode. The only other option is an EOS switch that doesn't open when it should. Every other problem would blow a fuse whether the flipper switches are pressed or not.

My question is, which fuse number is blowing? If it's not the dedicated flipper fuse, the flipper may not be the problem.

The important question now is whether your EOS switches are opening properly. Post some photos of your EOS switch with the flippers up/active (move the flipper manually). Your EOS contacts look kind of scary, so it won't surprise me if they aren't gapped well.

That sounds right to me. Let us know how it plays!

I suggest opening another thread with the new problem. That will get you the most attention solving your new problem. Once you've started the new thread, I'll pitch in with some ideas.
