Honored ContributorOK. I am not totally sure about whether you can reuse JTAG pins on MAX2 devices. I'd need to look it up!
You should still probably check that all your output pins are not connected to other outputs or power rails external to the PLD. Obviously after programming the device it enters operating mode i.e. it will start driving any outputs so that could explain why you see the higher current after config. I am not sure why disconnecting the ByteBlaster reduces the current. It still suggests to me that something is driving against a ByteBlaster output.
