Un traceable electric useage 12v

Following a recent 12 volt problem. I noticed with the 12 volt control panel turned off at the master I was still getting a discharge / usage of 0.1 amps, when the mains switch is turned on and the volt meter is reading the amperage goes up to 0.11 amps.

Every thing is turned off any ideas where to start looking.
