Hi all. I'm new here and new to working on pinball machines, but I have a lot of electronics/electrical experience. I've also played various pins, but haven't worked on one. An old guy nearby asked me to check over a Full House pinball he recently received from a family member. So far, it seems to mostly be working. It needs a few light bulbs and a bit of gentle cleaning, but nothing too serious. This guy wants it to work as it was originally, which means the coin mech too. I removed the mech and gave it a wipe down and adjusted it slightly, and it takes coins through nicely. The problem is that somebody has mangled up the switches where the coins hit the little wires. I assume they were manually adding credits at some point. I've straightened them out, but I don't know quite how they are supposed to look. Does anyone have a picture of what shape they should be? I would like to make sure they are lined up properly.
Also, the credit reel doesn't seem to count correctly. So here is what I have seen happen. If I put in a quarter, and there are zero credits, it counts up to 3. If I put in another quarter, it counts up to 6. If I put in another quarter, it counts up to 8 and stops there. It doesn't seem to go past 8, even though there are a lot more numbers on the reel. Also, if I put in a dime, it goes down 1 credit. And, if I put in a nickel, it goes down 2 credits. I'm totally baffled why it would do that. I'm sure there are experts on here that have the knowledge on this. Can anyone enlighten me on that? I have to admit I am really enjoying working on it. Any help is much appreciated!
