First check to see if the switches on the recognizer are to tight/close, so a "rumble" or coil fire initiates a switch hit.

If they look good, you may have a cross in wire(s) somewhere. You could check continuity between a switch lug and the shooter lane or whatever switch you think is causing the recognizer hit. Or it could be worse and be something on the board, bad chip etc.

Nice find! Did you try reflowing solder on the board? For the connector and leds?

I had a crazy through issue with the opto board on a sopranos, but the wire at the sling broke, so the opto board was still good.
