Batteries going flat

[jjr4]

We have an 08 Ventana that keeps draining the batteries while it is in storage. Anyone else have a similar problem?

Our old coach could be stored for months without the batteries going flat, this one will flatten them in 3-4 weeks from a full charge. Coach is "stored" with the store switch (in the overhead compartment) set to store and the engine disconnect breaker set to off/disconnect. When I come back in a month all batteries (chassis & house) are flat.

Any suggestions greatly appreciated.

Are you turning off your inverter?

Our inverter has power to it in spite of the house disconnect off. You might try turning the inverter off with the switch at the unit, as opposed to the remote, to locate the draw.

RJay, bigskymt,
I had assumed that the inverter would be off when switched off at the remote. The remote panel is off when the house cutoff is set to "store".

I will turn off the inverter at the unit itself and see if this makes a difference.

I still don't get why, even if there is a drain on the house side, all the batteries are going flat. There appears to be no isolatin to protect the chassis batteries from a drain on the house side.

Thanks for the help,
Jeff

If the isolator relay is closed, one thing draining could pull down all batteries.
