So working on a Jungle Lord, everything except the slings and top right kicker work. Solenoids work in test, switches do not to activate them.
I am a little confused on how these work. Manual says switches 17, 18
and 19 are dedicated switches with a hot wire and goes to ground. I see
a black wire that runs to all 3, but really not sure where it ends up. I looked over the schematics and it doesn't really show where it
terminates. Any ground I can find coming off the board?
Really do not want to start pulling wires out of the loom to trace it
all the way back.
Was curious if anyone knows where it terminates.

I don't know where it terminates, but I suspect the issue is with IC6 or
IC7 on the driver board.
You should see a voltage change from +5V to 0V on a J13 pin when the
sling or kicker switch are closed. The manual on IPDB isn't clear as to
which switch is connected to which pin. That voltage change can be
traced to an IC6/7 input pin which should cause a transition on the
related IC output pin.
If one of the special/switched solenoids is working you could measure
voltages on that one to see how it should be working.
