Is .5 Amp battery draw, while all off, normal?

[mgmillsa]

I just upgraded to a 2023 311RD and went to take it to service and was surprised by a dead battery. After I got it back from service, I turned off all 3 master switches (solar, inverter, & battery main) and my built-in Victron BMS is still showing .5A drawing. My old bumper-pull would easily last several months, and this thing dies in 2 weeks. My service tech said he's heard of the leveling system constantly drawing, but .5A is a lot. Thanks for the advice.

Well if the tech was worth his pay he would have put an amp probe on the battery cable and confirmed that by pulling the fuse for it. But the propane detector can`t be disconnected so that pulls a small amount all the time. The only way to solve this is to disconnect the battery cable or pull fuses till the amp probe stops registering a draw but I`m not a tech, just saying.

Get one of these and you can disconnect the batteries any time you want.

Our 2022 3791RD has the TPMS booster and the propane/CO detector powered on all the time based on the way those devices are connected at the "giggy box" from the factory. I can tell you that my leveling system is off completely once I turn off the power at the "giggy box". You can check yours by trying to power it on with the giggy box switch set to the off position.
Since I have the 400i solar system, the overnight drain gets recharged daily as long as there is some sun. Your 2023 should have at least 200 watts of solar, so if you are parked outside, turn off the "giggy box" and inverter, but leave the solar turned on. Then check your system after a few days to see if the solar is recharging enough to compensate for the overnight drain. If not, you will need to disconnect the batteries completely.
I've pulled the cover on the "giggy box" and may at some point move those two devices so they are controlled by the switch.
Good luck!!

I,ve been towing for many years but have never heard the term ,"giggy box". What is that?

A giggy box is the Keystone wiring termination point.

All 12 volt system connections end or begin in the box for easy location and troubleshooting.

Giggy box, why don't they call it what it is? A junction box.

I believe it is the guy that came up with it last name. Saw it in one of those keystone videos
