I admire your determination and drive. It is a learning process as well. As I learned with rebuilding a classic muscle car, it is cheaper to buy one already done. The sum of the parts plus shipping is more than it is worth at the end. That rule only applies to flippers, not to people who are on a journey and have no intention of selling.

I can relate, as I am trying to do a similar job with a Doctor Who pinball. I also followed the switch location list and found many were no longer stocked by marcos. I was lucky enough to find some used ones in France, Australia, Germany and Argentina. Gave up trying to find a project pin to rebuild. The trough switch assembly was the hardest so far. I am collecting parts, before I invest in a cabinet. Like the OP and others, it is about the hunt and the build and the experience. Maybe, I will document it once I get rolling but it will be worth half the value of an AF with the same WPC89 boards and similar switches and pop bumpers, VUK, ball popper, coils, and cabinet/head.

For Reference: Not specific to your AF but it is in the same family Bally 1992. Note how the Green wires go to the top of the switch and the white wire goes to the bottom next to the playfield. The diode goes between the white wire and another post on the top of the switch, but not where the green wire is attached. The silver part of the diode points toward the top of the switch.

I noticed this similar arrangement on all my roll over switches. I do not know why you have 2 diodes though. For that you need a wiring diagram manual.
