Ive got the bk up and running. Ive put a good 20 games on it so far, tweeking things out as necessary.
Its got a couple issues and I hope someone on here with a bk can help me.
The upper drop targets are not registering when hit, the coil works and they reset after each ball but during play if you drop the targets they stay down.
When I did the playfield swap I noticed there was a green wire with a black stripe not soldered to anything. This wire is with the wires going to one of the upper drop targets, could this wire be my problem.? I cant find any schematics specifically for bk so im hoping someone with a bk can take a look at theirs.
it is not the light green wire with the black dashes which goes to the drop target switches, it is a dark green wire with a solid black stripe. Any insight is appreciated.

I just had this issue on black knight. There is a green something wire attached to the left drop target (switch I think) of the right bank. This had broke loose and the targets acted as you just explained. I will take a look inside a little later if nobody else has the answer by then.

The Green w/ Black wire should be connected to the same spot on the drop target as the other Green w/ Black wire that is already there.

(Manual)
The green w/ black switch wire is the column power for the top drop targets and jet bumper.

The first picture is the right bank. Each bank of drop targets has a bundled set of wiring. That may help you determine which green goes to which bank of targets.100_7342.jpg100_7343.jpg

Thanks for all the help. Hereven is a picture just to clarify. The green with black dashes is connected to the first switch on the drop target assembly. The green with solid black stripe is not connected to anything. This is the upper left drop target.20140506_225853.jpg

yeah, your disconnected wire should be connected to the same spot on the drop target switch as the other Green w/ Black wire that is shown in the picture.

Mine has 2 green wires attached. I am guessing Williams used a different type of tracer marking on the second green wire on yours. Could be a difference in production dates. Mine is an early production game with system 6 power supply.
