Batteries
House and engine batteries discharging while unplugged. Coach disconnect button works every thing is off except LP detector. Batteries are new and check out as good. Coach only 1 month old. 2019 31B

Time to go back to the dealer to find the cause and correct.

I could be wrong here, but I suspect that if your LP detector is still getting power after you flip the battery disconnect switch, then that is the problem. The LP detector in our trailer will kill our batteries in 3-4 days (it receives no power when we flip the disconnect switch). I bet if you take the neg off the battery (physically remove it as an experiment) your battery will remain fully charged after a week of sitting there.

With respect to the battery disconnect switch and batteries drawing down....
A number of us have confirmed that a number of Georgetown units have their steps, awnings and LP gas detectors wired directly off the house batteries located under the steps. Therefore, even if you switch the battery disconnect to OFF, these get their 12 volts bypassing the switch.
That being said, ONLY the LP detector might drain the batteries, as the awning and steps only draw power when their switch is activated.
As far as your engine battery or house battery discharging, your newer units might have more parasitic toys still running in standby than my 2010 Georgetown. Fancier radios to maintain station memory? or the electronic control panel on newer rigs to replace the older command center.

X2 on CO/Propane detector. You need to move the power for it to the coach side of the switch. If it sat for a month, then this is the cause.

I think the LP detector is the problem. Thanks everyone

draw
Need to determine what the draw is on your lp dect. IMHO Atwood shows 75 ma, dont see that as not sufficent to deplete a rv batt in four days.

If you remove the LP as your drain, and the battery problem goes away, come back and let us know.

You can remove the LP 5amp fuse to test if it is the cause. You can also move the LP 5amp fuse from the battery to the side of the Battery Control Center (BCC) box, the no.1 stud. That stud is not powered when the batteries are disconnected. It is powered from the batteries when they are are not disconnected. It is also powered when connected to shore power or generator running from the converter. There are 3 studs on the right hand side of the BCC and the no.1 stud is the one at the top and closest to you.

Keep in mind that anything operated by remote can also have a parasitic draw. Things like DVD player, remote awning, remote levelers. These all have to be powered to be able to be remotely operated.

This is a NEW 2019 rig
If he really is turning off the lighted battery disconnect switch then all power to the motorhome is disconnect and the switch light should go out and all batteries are disconnect. That includes the Propane detector.
If the power switch it not light up when on then he blew a fuse in the Battery Control Center that manages the disconnect relay inside the BCC box

I only have a drawing of an FR3 BCC but the view of a 31B that I was able to barely make out did show 4 inline fuses connected to one of the coach batteries positive terminal. The FR3 BCC drawing shows the LP 5amp fuse connected to the battery also. The OP said everything was off except the LP and evidently that was because he saw the light in the detector was still on when the batteries were disconnected, otherwise, how would he know.

Iggy.....
Isn’t your Georgetown wired like I described in my #4 post with some wiring running directly to the batteries instead of inside the BCC box?

I have the 12-volt battery diagram for a 2019 GT5 31R5 and it is the same. 4 direct connection to the battery. - LP Detector
- Electric Step
- Step Override
- Solar Prep
I can't imagine the solar prep is a draw but rather an input.

So...
Where do you find the power for the awning?
That’s a wire I find directly off my house batteries?

I'm fairly certain it goes through the Multiplex wiring and is not wired direct. I'll have to check the diagnostic center next time I'm there. I believe there is an entry for it.

Light goes on and off. L.P. detector is suppose to stay on as per Forest River. Batteries seem to be holding steady at 2/3rd charge for 3 days now while unplugged

That is correct the way it is fused but if you want to remove it from the battery connection reference post #9 and then it will not be a parasitic drain on the batteries. Several models of Georgetown's are wired this way.
