@darthmango|new_window=true] okat that is interesting. No power from the charger to the battery. You did say you've checked the fuses for continuity correct? 2nd image top left quadrant, measure the voltage on VIN and VGND. Further down also check the BT- and BT+ TP (with the charger and the battery), see what you get.

@darthmango okay that is interesting. No power from the charger to the battery.

It's somewhat hard to see but the solder joint just above the VIN TP looks a bit odd and so does BT-Try to resolder that connector. Could of course be perfectly okay just my old eyes failing :-))

Check EM10 for continuity. That is your choke coil (filter) for the charging circuit but can interrupt your power circuitry.
Like @markusnorstroem already said, clean your board with some 90%+ isopropyl alcohol and see if that cleans up. Use something like this guide [guide|5825] to show how it's done :-) Yes, it was written for an iPhone 3G but all points are still pertinent to your board as well.
