Schematic diagram for the Apple logic board numbered 820-2523, packed as a RAR archive of 1.73 MB. The name gives no revision, so open the drawing and compare its revision block with the label on the PCB before trusting component values. Apple uses the 820-xxxx pattern for its own board part numbers. Once extracted, the PDF sheets help trace power rails, follow the power-on sequence, find which line pulls a rail low during a short, and locate sense resistors and enable signals feeding the PMIC and the charger circuit.
