LouisJB, let me "pipe up" for a second. First thing I suggest is that you check your charging fusefuse F7040. Use a multimeter and see if you have continuity. If you do not replace it with a 8A 24V 1206 SMC fuse.

Charging is controlled by U7000 which is a ISL6258A It is a 28 pin QFN package,7 solder pads each side. It communicates with the SMC to activate charging and then uses a push-pull FET circuit to generate the charging voltage. There is a current sensing resistor R7050 just at 3 o'clock position from the fuse (the green device) that feeds back the charging current information to U7000. It is a 0.01 ohm 0.5% 1W sensing resistor in a 0612 package.Check those components first and see what you get. You do want to check the components around the charging IC U7000.
