The battery is dead after sitting overnight. Replaced the battery and had the charging system checked it was OK. Hook up a meter to see how much it was losing.208mv. I pulled all the fuses under the dash and pulled the relays one by one but it didnt shop the drain. I also disconnented the alternator and starter wires didnt help! What to do?

This is a good one. I even question if a 2.08mv would kill the battery overnight. Use the following procedure to see if there is any difference.
