Hey all..

Still trying to chase down the reason for this battery drain on my 2007 DB9.

I have ran a voltage meter over every fuse after tricking the car to think all doors are shut buy clicking in the latches and leaving for 30 mins before I carry out the test.

The only fuse that showed any voltage use was the engine bay fuse 2 "Tracker/clock"

The tracker has been disconnected and deactivated. So only the clock is being used.

The total use was 0.5 volts. Doe's that sound about right? I'm in 2 minds to pull that fuse and see if it helps over the week.

I'm no electrical expert, but I think it's amp draw that you need to look for, have a look at this guy below, he's saying you should see no more than 50ma in the typical car with everything shut down.
