TROUBLE DIAGNOSES — Circuit Diagram for Quick Pinpoint Check
HA-41wiring diagramSchematic is a simplified pinpoint-check diagram; wire colours are not labelled, so all 'color' fields are '??' per the never-guess rule. Net topology reconstructed from the visible connections; conditional (M)/(C)/(WA)/(OA) legs are noted but not duplicated per condition.

Wire colours are not printed on this schematic — the diagram only shows topology with conditional-routing tags. Use code ?? for all wire colours on this page.
