Questions for everyone, my parents owned this machine for almost 20 years and now it's in my hands I'm restoring it noticed some issues in the process. On the backboard half the lights don't work. I checked the pigtails and even the wiring it all seems good. I replaced all the fuses just to be safe and nothing. #Space Station system any ideas where to start?

Your GI string is out. It is the Green/white strand. You should trace it out, and first check all the connectors.

You said you checked the fuses. Did you check for voltage at the fuses (with a DMM or voltmeter)? There are 4 branches for general illumination. Set your meter to AC volts and take readings with one probe on the solid color wire connector and the other probe on the same color with with stripe (i.e. probe on green wire, other probe on green wire with white stripe). These points are in connector 3J8 of the power supply

I traced the white and green wire it all seems good with the meter it all works till the board with the pardon my ignorance the board with a block all the connections test fine. The plugs are fine and not burned or corroded. They seem to stop here. They don't seem to continue to the main board but when I test the wires from this up to the board they work?

Double check your white/green wire to the interconnect board (left wall inside head), and then from the interconnect board to the 3J8 plug on the power supply board. Make sure you have continuity.

1 - should run to the GI strand on the backbox insert board. 2 - should run to the supply supply board, connector 3J8 pin 8

Side note, are you missing half of the lights on the very top light light board that illumated half of the space station logo?

Check the back of the relay board. The pins can crack.

So I look at the plugs you guys told me to check and I think I found the issue, the plugs look toast.

So how can this happen? Second do they sell these or do I need to clean them or 3D print new ones?

The relay board seems good is there a way to test it?

Any other suggestions please and thanks to everyone

The connectors are Molex .156 connectors, and you will want to also buy the Phosphore bronze coated pins for the higher amperage. You can buy both of these parts from GreatPlainsElectronics.

You will also want to reflow at least the header pins and relay (big orange box) on the little board you pulled out. The joints look like they are cracked.

This pin is cracked for sure, you should look at all of them more closely.

Quoted from Bowmallyboy:

So how can this happen?

Incandescent bulbs. Change to leds and no more trouble.

Well I got the pins and connectors and took this of to solder! Wow looks like someone modified this before.

Does anyone know if I'm better off to replace this whole board or re flow the board or can I just direct connect these with a more modern plug that allows more power to flow thru. Or does the rest of the board use power from these and I'm SOL fixing this mess.

That is ugly, but I am sure it works. Mine was burnt very similarly. Start with repining the connectors and see what you get. Check continuity on all your connections as you go. I wouldn't use a different connector than what is in the game in case later on someone wants to diagnose or replace a part.

That board might be hard to find as a replacement, especially one in better shape.

I would be cautious about that new connector, J1 on the left top. It looks to be installed the wrong way around?

Maybe that won't make a difference depending on what wires it is joining but I would check carefully first.

EDIT: - look at the picture in post #5, it shows that connector (J1 left) the other way around. I would trace the wires and confirm where they actually go to before powering up again.

Good catch on the reversed connector.

At least they chose heavy gauge wire for the jumpers. Check the wiring of the replaced connectors harness, it might be reversed as the board connector. You might want to replace both. You should be fine with that board, is there a specific problem with this board that you are troubleshooting it? I don't really see any cracked pins in the photo. As far as different connectors go, I really don't care for the IDC connectors for carrying high current. When it is necessary for repinning I change the cable end to the molex type with crimped trifurcon pins, replace the board connector with male molex locking connector, and then it lasts basically forever.

Thanks everyone I got all the lights working and restored. Now I've moved on the second issue. One of the pop ups is stuck ingauged. I've replaced the switch and motor and it still does it. I cut the wire of so it won't burn up and the entire machine worked perfectly for 2 weeks now all of pop ups and the ball eject from the ramp don't work. Any suggestions?
