So what is not working?, It sounds like the game is coming up. When a Bally game comes up it kicks out all the ball locations like the saucer and kicker in case a ball is stuck there. That's part of the boot. Afterwards the LED on the MPU flashes dimly which sounds like your B&I (that's the official name of the Weebly board) is doing. Are the displays lit up? Can you press the self-test button on the front door and put the game in test mode?

Is this a multiball game? Or better question, does the B&I board think it's a multiball game? Bally games with more than one pinball will boot and not come on line if a ball is missing. So first thing I would do is check the MPU and make sure it's set for Future Spa.

Once you confirm the B&I board is set properly for FS put the game in switch test and make sure there are no stuck switches and make sure all the ball rest spots like the outhole are registering when a ball is there.

That green wire shorted the GI bus to the switched bus. No wonder the fuses were blowing.
