Nishijin C wiring issues

[SimonCat]

After introducing myself in the "Introductions" section... I wanted to ask my first technical question.

While working on a Model A restoration, I began to trouble shoot the wiring issues afflicting my Model C. The previous owner did a real job on the wiring and I'm trying to sort out how this thing should be wired. What I've discovered and tested thus far is:

- The lights seem to be powered by a 10v circuit (I've tested these using a 9v battery and they seem to work appropriately)
- The machine has a 24v solenoid that is triggered by the jackpot and actuates the tulips (opening them all at once)

Questions:

- I'm not sure how this machine was originally powered, such that it provided both 9v and 24v power to the lights/solenoid. Could someone enlighten me?

- I've tested the solenoid using a 20v dc power supply... directly to the solenoid leads (2 red wires) and it seems to work. I don't understand the electrical components to the right of the solenoid, however. When I used the power supply on those leads (1 Orange, 1 Red), nothing happens.

That's about as far as I've gotten. I'm trying to strip out the wires that seem added/rerouted by the previous owner, but I'm really just spitballing it. Any guidance would be greatly appreciated.

An update & to close the loop... I figured it out. The previous owners had this machine wired really wonky. That threw me off. The orange and red wires that feed the solenoid relay must have been connected to a transformer at one time. In fact, when I looked more closely, I found three small holes where staples must have held the old transformer. The switch for the solenoid is buried within the jackpot channels. Once falling into the center attraction a ball has 4 holes that it can enter prior to triggering the jackpot. If it falls into the center hole of the center attraction, a switch triggers the solenoid and all tulips open. Using a 24v battery charger, it all works as it should. Finding a transformer to power the machine shouldn't be difficult, but I would really rather use a rechargeable battery of some kind. If any one has a suggestion for how this might be done, I'd love to hear it.
