R1580 is 3.28v on USB_EXTA, 3.33v on PP3v3 - 98.3kohm
R1583 is 3.21v on USB_EXTD, 3.33v on PP3v3, - 78.6kohm

Don't suppose the 13" air version ribbon could be used to test with could it? I know it isn't the same shape but I have one to hand is all.
I have found that if I plug the charger into another mac...
