Wire disconnect in unit

Though I have been looking at the schematics for this unit, I have a green wire with inline fuse 1 end connected to the 4 pin power junction on main pcb, but can't determine where the other end connects. I pretty sure it is the sense wire for the battery charging circuit, which probably should be connected to the Ac/ charger jack on back panel, but not sure which pin. Anyone have a suggestion?
