Update: My friend Chet and I repinned the male and female side of the playfield connector in the cabinet for the two corresponding wires for the rollover lane we are having trouble with. This didn't change anything- exact same results. We then alligator clipped a wire to one lead on the switch and I added a trifurcon connector to the other end, popped out the factor wire, inserted the new wire in the molex connector that we previously swapped for the factory IDC connector, no change. We next moved the alligator clip over to the other wire on the switch, same thing.
Does anyone know what to look at next? I think it's safe to say we pretty much ruled out a connection problem with running the new wire from the switch in question to it corresponding pin on the board connector.
Something else I stumbled on that I felt was a little odd is we were playing a friend's Road Kings last weekend and their's was having an intermittent problem on the same switch I'm having problems with where sometimes the switch would register and sometimes it wouldn't, but every other switch on the game seemed to work fine. They said they have cleaned and adjusted the switch, but it continues to act the same way. Could it be there is some kind of design flaw with this switch registering?
