If I leave our trailer parked for more than a week or so, in storage, I come back to a dead battery.
Battery switch turned off for storage.
Inverter is turned off.
No solar connections.
The battery switch does NOT disconnect power to the leveling system or the inverter. I don't understand why they do this from the factory.
Does anyone have any experience with this happening?
I am going to work thru this disconnecting the leveling system and inverter, and use an ammeter to check for
parasitic current.
Thanks for reading.

Hi. Please don't disconnect those critical systems. They are in place for safety reasons. They shouldn't be a draw on your battery unless they are in use. If you have to do something, then disconnect the battery terminals when you put it in storage.
Maybe I read your post wrong and you're only going to disconnect those to troubleshoot? I'd leave them connected and troubleshoot first. Are you sure your battery is good? Have you thought about going to a bank of batteries rather than just one?

I put a proper switch right after the battery that disconnects everything, the safety police will be along shortly.

I agree these should not drain the battery, however, the leveling system is in standby mode anytime the battery is connected, with or without the battery switch being closed. |

The only other thing is the propane detector would need power whenever the trailer is occupied. Get a quality switch such as the Blue Sea brand, another option is one of those that mount directly on the battery post. I had two of the cheap "red key" type switches fail in a very short time. |

So, I sent my question off to KZ customer service. They said that the disconnect switch was wired wrong.
Gentry said the leveler and the inverter should be on the load side of the switch. I will correct this first and see if it solves the issue.

In my experience, with my old Komfort and my current '17 Durango 1500, the disconnect kills =everything= inside the coach leaving only the jacks and slides hot.

Quick update... The ground control leveling system is drawing 175mA of current at rest. This will kill a lead acid battery in a manner of days. Drawing shows wiring for 12V main power.  |

As far as I know, the only thing that should have power supplied to it with the battery switch off is the electric brake switch that turns on the brakes if the trailer disconnects from the tow vehicle.
The assumption is, when the battery is disconnected, the trailer is unoccupied and no 12V circuits or any detectors are needed. Only the towing circuits, the brake disconnect switch has to be connected.
I usually disconnect the positive connection to the battery when it's in "storage" in my driveway. When I had to store it at a different facility, I removed the battery, propane tanks, etc. as theft protection.
