Will not charge unless I turn it off first

Having a really weird issue with this iPad Air that I'm working on. It will only take a charge if I plug it in while the device is turned off first.

When the iPad is on and I plug it in, it doesn't say it is charging and pulls 0.01A (I have a USB Current meter similar to this one.)

However, when I turn the device off and then plug in the lightning cable, it turns on, says it charging, and pulls ~2A.

Another weird thing, the iPad seems to power the USB current meter when I unplug it from the brick. So it seems like current is flowing out of the iPad instead of in. Also when I do get it to charge and I unplug the power brick from the wall, the iPad still says it is charging.

Any ideas what could be the issue? I was thinking either the dock or the board.
