Alright, so I just picked up my first Pinball Project, a Williams Alien Poker Pinball. The flipper fuse is in need of being replaced and I'm not entirely sure which fuse to replace it with. I've found 3 separate sources that each say something different. Pinwiki says Williams system 6 boards need a 10amp FB fuse, pinball.flippers.info says to use a 10amp SB with system 6 machines with 2 flippers and a 15amp SB fuse with 3 or more flippers, which I believe they got from a Williams power supply board schematic. The 3rd source is the Williams Alien Poker Instruction Booklet PDF from ipdb, and it says to use a 10amp SB. The old fuse is a 10A AGC fuse. I also noticed that the power supply board has been replaced at some point in the games life, and it looks like it came from a Firepower machine. (Someone wrote FP on the sticker. I know that probably makes no difference, but just in the off chance that is does) So which is it, 10amp FB, 10amp SB, or 15amp SB, since the game has 3 flippers. Not that it matters, I included a image that has screen captures from the various sources rolled into one image with the URL of the page I got them from under each section I'm sure it's probably overkill.
