I'm trying to bring a Space Invaders back to life. I put in a new rectifier board and repinned the connectors to it, and also had all the boards redone by a professional. However, when I turn the game on it boots fine and shows 40 credits, but it won't start a game.

When I run a test, it shows solenoid 10 and 11 not functioning, (the coin door and the flippers). Even if I close the coin door solenoid, it doesn't help. I also ran a switch test and it showed switch number 15, the clone target chamber, as being closed. The problem is that it is open and there doesn't appear to be any way it is being shorted. I have not reppined the connectors on the boards in the head, as they all looked with no signs of burn, looseness or corrosion. I'm more of an EM guy than SS, so any help would be appreciated.

Thanks

Not sure how to check that in the switch test. It just lists switches there are a problem with and the only one that comes up is 15. Is there another test I'm missing?

I tested for continuity with the two switch blades and there is none. There is continuity when I test the tabs the wires are solder to, but they are all connected by diodes, so wouldn't that create continuity there? (see attached photo).

Thanks

I believe all the pins on the board were replaced when rebuilt. No luck with wiggling.

Yeah, I suppose i will have to. Was really just hoping it was something simpler. I just hate repinning.

Thanks
