Parasitic draw??

I recently spent a week boondocking with my new chateau 22E. I installed a Victron 720 battery monitor before the trip and I noticed a constant 0.5 Amp drain, even when everything seems turned off. Playing with the fuses on the DC circuits I managed to identify the Audio/Video circuit as the culprit. Anyone knows why this is happening and how to get rid of it (besides taking the fuse off of course)?

Is it the power to the radio to maintain the clock and the radio pre-selects?

I didn't think of this but that sounds like a possibility!

.5 amp sounds like a lot for the radio memory line which I thought was on the chassis side anyway. But .5 amp sounds about right for the TV antenna amplifier.

The amplifier was my first guess indeed. So I hopped on the roof, unscrewed the cover of the Winegard connect 2.0 and unplugged the power feed. This turned the LEDs in the sim card box off but didn't make a substantial difference to current drawn ...

,5 also includes the CO and LP detectors. They must be powered at all times. The radio circuit is the house radio. Not the dash radio.

I don't have a house radio ...

I still haven't found a fix other than taking the fuse out ... which is not very satisfactory but works ;-)

I think this has been debated before, but according to this page:

https://winegard.com/products/cellul.../connect-2-4g2

The Winegard Connect 2.0 has nothing to do with OTA TV so it would not have the TV amplifier in it.
