I have an Area 51 board that will not track the gun for Player 2. Both guns work and swapping the harnesses results in the same thing... Player 1 gun tracks and triggers, but Player 2 gun triggers but does not track. I believe this makes it a PCB issue. I've checked continuity on all the pins and redone the solder on the header pins for the connector. Ive also touched up solder on the 74LS14 that the gun inputs feed through. No change on any of it. Does the gun tracking get handled by the 74LS14, or does it just handle trigger inputs? Perhaps there's another IC that handles the tracking(?)

Any help is appreciated.... again, the guns themselves and their harnesses are fully working, with full continuity from the board to the gun PCBs.

Thanks.
