Apple logic board 820-1524 schematic archive, referencing drawing 051-6582 at revision C000 and packed as a 1.21 MB RAR. Apple separates the 820 board part number from the 051 schematic drawing number, and this board has several drawings on record. The contents are likely PDF circuit pages, though the name does not confirm it. Use them to trace power rails, follow signals between chips and locate shorted components, after matching the drawing revision to your hardware.
