Dead Battery

[magic]

Yesterday my battery just went dead. It was a new battery not even a month old.
I had the alternator removed and got it checked and it was fine. Then I had the battery checked and it was fine. The Expy would start with a booster start but slowly the battery goes down. I am baffled and so is my mechanic.
Any help would be most appreciated.

Thank you

What's plugged into the "lighter" sockets?

If nothing is plugged in you need to put an ammeter between the battery and the system to see what's bleeding the system.

nothing is plugged in the lighter socket. However I did connect the subwoofer( this was factory fitted but when I bought the Expy it was not working) The technician who connected it said that the the connection was loose at the dash board end and this was done about 3 weeks back.
