On Pirates, I noticed right pop switch not registering along with plunder #6 target. When I go to active switch menu, all switches in that column are activated. Tournament Start, Right Bumper, #6 Plunder Target and Ship Home. When I open Ship Home switch, then the other switches work and all active switch indicators go out in diagnostics. I disconnected the tournament start via the molex plug, replaced diodes on pop and home switch but problem persists. I believe that when I activated the ship sunk switch, a similar active switch happens in that column. One other possible clue, when I plug in the switch connector for the 2 ship switches, the right pop fires just once. It also fires once after a ball is kicked up from the trough and activates the shooter lane switch. Any suggestions on where to continue looking?
