Replaced dock connector and now no longer charges?

jackie1, since you are not sure if you if you turned it off, check your fuses for continuity. Here is my answer to a similar question. "I posted another one of my pic's for fuse location. Dimensions are 3GS fuse is 2mm x 1.20mm and the 3G one is 1mm x 0.30mm approximately. This information is from my notepad and not sure where I got it from, but I do believe it is from one of the forums. So I would like to give credit to the anonymous author ;-) Based on these specs the appropriate part number (Littelfuse Inc) seems to be 0435002 for 3G and 0467002 for 3GS. A small note about 3GS: the above fuse size is 0603, a little smaller of the original. The correct size is 0805 (2012 Metric), but unfortunately Littelfuse doesn't have this size available. An alternative could be MFU08052 from Vishay/Beyschlag Inc." previously answered on here. If you find that your fuses are okay consider getting a new battery. If none of that works, you may have to replace the power management IC on the logic board. You also want to check that connector 4 is on and clean, check the battery screws under don't remove sticker are on properly Hope this helps, good luck.
