I'm officially in! This game looks super fun, even though mine is a fixer. The guy bought it 20 years ago and eventually stopped paying for maintenance. He didn't know how to take the backglass off so I know the balls weren't changed in that time. The upper playfield is especially torn up.

Batteries are super corroded, pulled those out instantly and just bought a nvram. Anyone want to airbrush up my playfield? Haha. I'll probably clean as best I can and wax a few layers ... maybe with Mylar as I don't know when/if I will go for a CPR. I'd be interested in thoughts on that.

Quick question, my plastics that should be next to the flippers are gone, but what's in the metal guides are the wrong screws even if I can fin/buy those plastics. What type of screw/post will I need?

I'm looking forward to playing this one with my kids!

Interesting, yeah, those are the ones I saw. I was watching some video on YouTube and saw others with steel, good to know I'm not missing pieces I guess haha!

That upper playfield is supper rough and bumpy ... I gotta think about what to do about that. Gotta go with Mylar to help smooth it out right? Or maybe I find a place to just do the work on the upper ...

That would be awesome! Especially if I can start from a better position that this one, there are some more detailed sections that will be tough to manage, and in general it is just rough.

Ok, need some insight from you guys. After cleaning I'm putting back the wires in the head but it looks like I might be missing a few? I don't see any hanging anywhere, and I didn't take anything out. (At least I think I didn't?) I also see a lot going on in the bottom right of the head that I don't see in other pictures in this thread. Any insight to what I might be missing?

Hmm, that goes in the "not cool" column to me! Is there a way to get the mod to run back through the relay?

Also, good to know I have a separate booting issue. This happened at the guys house I bought it from, and is happening now. When I flip it on, the inside digit flickers 0, with the same happening to the scoreboard (a single 0 digit). Basically not booting. I read a bunch earlier and tried googling, but not seeing that same issue. Thoughts?

Oh, there's also a loud humming sound from the speakers ...

I wish I could tell, I can't get the game to boot, it just flickers a "0" digit inside on the battery board, and on the scoreboard when I turn it on with a loud humming sound. The 0 digit happened when I bought it, and the reason I got a deal (I hope), I'm not sure if it had the humming sound though.

I'll try to check tonight, I'm still learning so I might have questions on how to do that, but will google first to not bog down the chat.

Awesome, thanks Frunch. I caught a few fuses that were quite a bit different than they should be. Not that it will fix things, but I'm interested to at least see if a few more things get going. I also found someone that is more experienced and bulletproofing the boards, so might do that as well. Not sure yet, I might turn back to my Black Pyramid and finish that up so I can free up some space (and cash) to go at Black Knight.

That's funny because my lower is great and my upper is toast!

I might get the plastic playfield protector from Germany to make the surface smooth for the time being.

Hey Hawk, can get get a look at the upper you have too?

Ok, I’m back on this. Black Pyramid was sold and the boards are back from being refurbished, bulletproofed and a NVRAM installed. Unfortunately when I fired it up, the pop bumper solonoid burned up! Aside from that, there are still lots of issues. I went through the switch test, and I fixed them one by one. Nothing new pops up, but only the top left drop targets reset, the rest don’t pop back up, the magnets don’t work, the middle ball lock won’t pop out the ball, the ball trough won’t pop the ball to the switch 17-19 area, and the ball doesn’t pop into the shooter lane.

So big stuff still not working, and I need a new digital tester. What does work are the rollover switches, the spinner and middle ramp gate, lights, scoreboards and the top left drops.

The question is, where do start for the next stage of fixing?

Interesting, I hope that’s it! I went through all of the fuses though. Which fuse runs the solonoid s?

Also, I just completely disconnected the pop bumper for now. Would that take out the other solonoid?

You know, i did not keep those 2 wires connected. I’ll try that!

Edit: just connected those two wires. I’m back in action! All solonoids and drop targets are firing! Thanks man! Now, the sound is the last Thing that i need to figure out, still not on?
