you should also listen to the bill acceptor and note as to how it cycles and if the machine works, and with the door closed and ready to play, the yellow bv insert denom.

If it works then all you need is the CC-16 24vac. you can test the machine several times in this mode. if no failure codes, you should be able to test the machine by pressing the small white button on the optics board( directly beneath the missing coin comp.) this will put credits on the machine. pay attention to the winner paid display, all failure codes are displayed here and a legend to what they mean is on the front door light panel. next see if there are any numbers on the display. then see if the reels are locked (they don't spin freely) this will check all the power supplies/fuses. to get a better understanding of what condition the machine is in, turn it on and look for the following! do all three fluorescent lamps come on? does the denom lamp come on (provided the bulb is good) you can swap the insert coin and coin accepted or the bill validator bezel lamps to see if it works. It depends on how bad you want the machine.
