I've scoured the net and only can find the Instruction Manual.
Anyone have the schematics on this? I don't wanna shell out the $30 bucks for a copy on ebay..

I think there is a Jungle Lord schematic available on the web. It should have largely the same guts, but not exact. Otherwise I think places like Marco sell them, but I haven't found one to download yet..
I have one somewhere, but I will have to find it. Did you already find this operator's handbook?

For all the boards, Jungle Lord schematics are identical and IPDB has those available for download.

Hans, thanks.. quick question though: As my BK has a system 6 power board, won't there be some differences?
Although not specifically BK, check out http://www.firepowerpinball.com/ Richard has redrawn all the System 6 schematics, see the Tech Support page. For the most part, all of them still apply to System 7, and since your BK has a System 6 board it should be the same.
Power supply diagram will be different, just use the standard System 6 diagram for that. There will be an extra relay in the GI lighting harness.... but that's the only real variations from the later Black Knight machines.
Any questions you may have, shoot me an e-mail. BK is a bit of a speciality of mine.

Hans, here is the GI relay (I believe). The only lights out are the lamps under the inlane guides. All backbox lights and other GI are on. I think this connection (in the pic above) would connect to a system 7 power supply, but as I have system 6, it's not a necessary connection. Then again, I don't know...
Yep, that's the GI light relay, and it's missing two wires. The yellow wires on there are the AC power for the GI lights, but the two wires that activate the relay are missing. They would normally connect where that diode is.
I'll have to check my schematic to see which way they are supposed to go.
-Hans
I think I also replied via e-mail, but will put it here too.
The GI lights are normally on, but in some instances the relay is there to flash(strobe really) them off as part of the visual effects, such as before starting multiball. Black Knight was the first Williams game to do this. Makes a big difference to be honest, once you see it work properly.
The red wire will go to the banded side of the diode on the relay, white the brown/orange goes on the other side of the diode.
-Hans
Wow Hans! You think I should just cut the connector and solder those wires on there?! This would be my first soldering experience.
And I should just leave the diode on there correct?
I wonder why those wires are housed in a connector with the relay on the backbox? If this is an early run of BK, shouldnt those already be soldered on?
I'm curious myself why it's disconnected, it should have already been connected. I'm not sure if there was another pigtail that would have gone between there or not for the early style machines.

Thanks hans. You've been a great help. I saw your BK website. Pretty cool info on there.
I'm gonna try to solder those wires on when I get back to ny ... I'm in Ohio w the in laws for the holidays.
I'm guessing a standard soldering iron will do.
Is there anyway to test the relay prior to soldering the wires on? Would holding the wires on the correct lugs w electrical tape and causing the relay to work ( by getting multiball perhaps) be enough of connection to test ?
If I was going to test before soldering, I would use test leads with alligator clips. You can just connect whatever wires you want as experiment before soldering.
If you aren't familiar with these, they look like car jumper cables but MUCH smaller.
Interesting. And theyre called "test leads"?
Where do I find these? Radio shack?
I'd love to test prior just to make sure the relay does indeed work.
Yes on all questions. Radio shack does carry packs of test leads. Some GOOD auto parts stores will also have them. Personally, I find them overpriced and usually make my own from the packs alligator clip and lengths of scrap wire.
This would make for good soldering practice too.
-Hans
You can get them at Radio Shack or any Autoparts store.

Honestly I can't believe how much I'm learning.
Thanks fellas. I'm gonna test out that relay first. Who know, maybe there is a reason those wires aren't connected.
