What protector did you use? Have had my bk for 30 yrs. So it has some wear. Dont want to overlay it until needed. A protector may be an option for me.

Thanks for getting back to me so promptly. The protector is just a clear non sticky plastic that is held in place from the various playfield items/posts correct? Not like a mylar that sticks to surface.

I'd love a "mint" play field. But realistically I wanna play the game not collect dust because of afraid of wearing it. My playfield is not terrible. So if I can slow down the wear to the point I wont need to hardcap any time soon it I'm ok with that.

Only issue I have with clearing is the time. If the field was mint yes I'd do this.

But for a player the time vs reward not there.

I'm way to anal to start doing restos. I work on euro cars for a living. Last shop I worked for was a high end exotic car place. OCD and attention to detail is good for what I do for a living.

Yet it's bad to my wallet when it comes to personal projects be it car/pinball/ house etc. The 50 more dollar syndrome kicks in. The 50 more dollar syndrome is basically while in there- what's 50 more bucks to do this or do that. Before you know it an easy fix turns into a full out money eating rebuild.

Dont get me wrong, it may happen to black knight at some point because of my sentimental attachment. It is my 1st pin. Got it when I was 8 yrs old for Christmas 30 yrs ago. Parents snagged it used from a local vending vompany off route for like 400 bucks or something like that. Even after my parents split and my mom and I had nothing- she kept the machine.

In the lean years we had no living room furniture and a tiny living room at that. the black knight was broken and used as the tv stand lol.

Can you take a pic little further away to see everything? I literally just finished maybe 10 mins ago a complete led swap and fixed the roll over switch in back left corner that gives you the free ball after both bank targets are set. So this is fresh in my head.

Edit- that looks like the leaf switch was replace with a micro switch.

So the yellow wire is the one not hooked to any thing? I assume that switch is not working currently. On my machine the yellow is ground. They are tied to other switches like a daisy chain then pulled to ground point or are tapped into the thin braid ground circuit that is stapled through out the underside of the board.

When I was changing bulbs had a few that were soldered to the 1/4 hex bolt that screws bulb holders into playfield.

Before you solder it back down alligator clip jump it to test it.

Based on wire length I'd guess it was tied into the same color yellow wires seen at 5-6 o'clock in above pic. Solder joint probably cracked from either vibration or lifing playfield.

Learned something new today. My machine is setup on 38- no locks carry over. That's how I have always played it. All local places that have a bk are set this way too. 3 ball game I'm at a 3.1 mill. See attached pic. And yes I'm in dire need of a back glass.

Havent gave the machine much love lately though as I drug home a cocktail machine to fix. To do so I rearranged existing machines. I now got 1 hell of a slope to the right that is driving me nuts. Gotta pull glass and level machine again.

By any chance does someone have a schematic of the driver board? Save me from pulling board and testing path with meter it would be appreciated.

My jet bumper is not working on upper playfield. Coil fires in test mode. No switch errors. Continuity test switch at bumper and confirmed open/closed.

Pulled back glass disconnected special solenoid connector and can apply ground at pin and pop bumper works.

No blown fuses or warm to touch or melted transistors visible. Game plays fine otherwise.

Correct- pulled 2j13 that runs flippers/jet bumper. Can ground pin and respective coil fires.

Did not check voltages at spoon switch. Just tested if switch was open/closing with multimeter while game was off. When I get home I'll sort through diagram.

Update to my pop bumper issue. Pin drag issue at power supply on connector 3j3 was my issue.

Game is back to 100%

Can someone chime in please- I know I seen pics of an black knight that back glass was different as well as the apron. Wanna say back glass was in spanish? Was an export market game that another company made under liscense if I recall correctly.

Can someone post name or even better pics?
