Apple logic board schematic for board 820-4924, with the name pointing to revision A and model A1502. Apple prints the 820 number on the logic board, so verify it and the revision before using the values. Engineers rely on these pages to follow power rails from the charger IC through the main regulators, check sense lines and find the parts behind a short. Open it in any PDF viewer and search by net or part designator. Combining it with a boardview file makes physical component location much easier.
