I can check when I get home.

Yes.

Sorry for the delay. I attached a picture of my wiring.

Unfortunately, I am not seeing the wiring you are describing. My odd-colored wires are soldered to the anode of the diode, and the similar-colored wires are soldered to the quick connector that attaches to the switch blade.

I wouldn't put any stock in the wire colors, but the configuration will be key. My guess as to why my game only has a single wire to the control room switch, is that the two switches share a common positive or ground, and the other wire goes to the switch input of the CPU.

Do you have a multimeter you could use to probe the signals? Switch depressed and not.

I'll trace the wires back this afternoon. Maybe my wiring is not as it should be!

Also, I forgot to post this earlier: http://www.sternpinball.com/downloads/sb43.pdf

May or may not apply to your game, but it's worth checking/doing while you're in there.

I'm having the same problem with my JP control room switch. Here's a pic of my obviously fooled around with switch. This is how I found it (minus stripping the loose wire). I'm not sure where this loose wire goes though. Any help would be greatly appreciated! Thanks

I just replaced the one at my house this week. I'll grab a picture in a minute.
