WMS IJ recently started pulsing the subway lockup coil. Pulses it about every 8 seconds like clock work. Does this in game over mode as well. Verified all switches mechanical and optical are working. Replaced subway opto transmitter and receiver. Game passes self test with no errors reported. Have gone through and tested all switches indvidually. Connectors are all where they are supposed to be and everything else in the game works. Stumped on this one. Help appreciated.
New! Dark mode!
