RAR archive for Apple logic board 820-1441, also carrying the schematic document number 051-6680 at revision F000. The 051 prefix is what Apple uses for its schematic drawings, so the archive most likely holds the board schematic, but extract it to be sure. Use it to follow power rails, check the sequencing of enable signals and find the part feeding a shorted line. Before relying on it, match the 820 number silkscreened on the PCB, as each logic board revision has its own drawing.
