@dconsmack here is the guide for it [guide|561] and double check your work. always double check the dock connector. Check for bend, broken or corroded pins as well as debris. Try a new cable and try a different charger. It is possible that you have a bad battery. Try to replace it once more. It is also possible that you are having issues with the actual battery connector. It has the tendency to break of that board. Carefully double check on that. Anything past this will be related to the charging circuit on the board and schematics are not available. It would put you in the having to replace the board category.
