Earth continuity test
1) Referencing pages 25 (Wiring Diagram), and 27(Control Board Layout) of this
Document, disconnect the 6 way male connector and Red and Grey flying
leads associated with the 8 core cable (#2 Charger Box Interface), the 7way
male connector (#3 Carriage Call Station), and the 3 way male connector (#4
