I have an old "scorpion" pinball (1980 system 6) we took on trade for doing some work.
it's cosmetically in okay shape but the wiring under the playfield has been butchered.
someone had taken it upon themselves to swap out some coils and then place the wires on in random spots.
I'm trying to get everything wired up how it should be and i've mostly got it (pretty standard stuff), just having some issues with a couple connections.
This pinball has 4 flippers (2 on the left and 2 on the right)
The upper playfield flippers are all standard wiring and I have those sorted out.
but the lower flippers are a little weird.
the flipper buttons only have a single switch with 1 wire going to the coil... so it looks like there is some normally open switches attached to the EOS as well. i believe these are to activate the upper flippers.
so there is a wire that goes from the lower to the upper flippers. Obviously i need to attach this wire to the NO switch to activate the solenoid when the lower solenoid is activated, cool, not a problem, but what does the other side of the switch attach to?
Do I just need to tag the other side of the switch onto the flipper button wire connection? (to path it back to ground)

okay, i managed to figure things out from a grainy photo someone posted on the internet.
it basically showed that the lead from the flipper button goes to the lug on the coil like normal, carries on to the switch (for bypassing the 4700 turn coil) and then is looped onto the switch that feeds over to the upper coil. (shown in my crude paint pic below as orange wire for simplicity)
