Flat battery after 2-3 days

[dornish4561]

Found the issue of a brand new battery drain after 2-3 days . Being the fuse for the interior lights  and the radio - not looked into yet due to the weather only removed the fuse as a temp fix. As far as i know all the interior lights work correctly and so does the basic stereo . What could i be looking for as the issue draining the battery. 2007 honda accord 2.0 155bhp saloon

Sometimes it can be a tough one to diagnose.

The best way would be to attach a multimeter to the battery and then systematically remove fuses until the current drops then you'll know where the faulty circuit is located
