I've got a problem on my Class of 1812

I have a single switch stuck on. Switch 51 which is the left ramp. Every other switch seems to work fine, no switch is triggering anything else, but 51 is just stuck on.

I know the switch and lamp matrix and tied together so I also have a lamp matrix issue. A bunch of lights come on with other lights during controlled lamp test. Examples would be, shoot again triggers the Door Prize light, or the 20,000 led on the ramp riggers the middle arrow on Zomb's.

I tested the lamp matrix colum by grounding the associated transistors and the lights only come on for the specific colum I am triggering.

I also removed A1J5 from the CPU board and switch 51 was still showing as stuck on in the switch test.

I tried swapping CPU boards from my Surf n Safari and the issue did not follow the board.

Then I found that the diode board under the PF if I removed the connector from that board that the switch stopped triggering. So I assumed that it might be an issue with the diode board

But there is another diode board in this game that no switches on it are having any issues, so I plugged the connector in on that diode board and the issue was the exact same, which to me rules out the diode board as the problem.

I'm really not sure where else to look at this point.

Any help would be appriciated.

It's a micro switch, but I have disconnected the wires and it's still stuck on

Dam, was hoping it might be something else :/

The one strange thing was I can't tone out the switch to the diode board

If I could figured out exactly which switch on the diode board it was, I could try and remove that single wire from the connector I guess and then rewire it myself.

hmmmmmmmm

Well I pulled the wire I thought it was from the connector on the diode board and apparently that wasn't the wire. It's purple/purple from the switch, but the purple/purple that I pulled from the diode board didn't change the issue .

I think I might replace the connector, one pin at a time and see when the issue comes back

Just need to buy a connector and pins first though

Not in the game it's not, it is a Purple/Purple.
