So I have a 3 player Rampage that works perfect, except Ralph won't move to the left. This is the only control that doesn't seem to work, I've checked continuity from the harness all the way to the board, I've even checked directly at the board and I'm still getting nothing. I took the board out and reseated all the chips I could, still nothing. I'm just wondering where I should look next? Any help would be appreciated, thank you!
 
Stupid question, but did you check the switch itself to make sure it is making correct contact?

After that it seems like something with the logic, but that is above my pay grade.
 
Yes the switch is fine, that's why I mentioned that I've checked the connection all the way to the board. I even tried it on the pins that the harness connects to at the board. I guess my real question is where should I start looking in the logic, the resistor and capacitor in front of the LEFT pin also tested good

Sorry it just stated continuity from harness to the board. Which is why I asked.

The realm of logic is beyond my grasp, hopefully one of the Midway Gurus will jump in. It might be worth dropping Broodwich a line. He is pretty good with these guys.
