I picked up an Atari Space Riders pinball last September and have been looking at it bit by bit but am still stumped. A fellow KLOVer came by and fixed it up a little bit, removing a lot of extra wiring that should not have been there. He also replaced the transistors on the main board and I have replaced the EEPROMs with a pair I bought off Marco Specialties. The issue continues as you can see in the video below.

If I remove one of wiring harness edge connectors like the yellow or the red (solenoids), the same thing happens. If I remove one of the connectors on what I think is the aux power PCB (the one on the center left that is attached to the side, next to some fuses), then the 0s on the bottom of the scoreboard continues to move along but no other lights flash and the game just buzzes.

Now one other thing - if I attach the power to the upper left solenoid that is supposed to control the left drop target, it will constantly fire. There is also a solenoid assembly (to a drop target) inside the game that is unattached, looks like the solenoid had melted.

I see that there is a person on eBay that does repair for the main PCB or the aux power board for Atari pins but if it comes to that I'd rather send the correct board the first time.

Here's the video:

Thanks in advance - this one obviously needs a bit of work but I would love to figure it out and get this into my arcade to boost my pin offering
