Looks like don't mean much today. That can could house a solid state regulator. The pictures help. The tiny copper traces serve as fusible links in a overload state. We've seen it at the limiter several times in this forum over the years. You wouldn't want to smell that board burning. You could patch your board but reproductions are available. Main thing is find and correct the faults that would ruin another board. Sadly, a fault can be as far as the fuel sender away from the board. Short that wire to ground and watch. No don't really. Best of luck with it.
