Lithionics large phantom draw

[DaveAndBecky_NorthernMI]

We have Elite II Pro package with 3 Lithionics batteries. Currently boondocking near Capital Reef Utah. I checked batteries mid-morning with good sun and saw 2-3 amp draw on each battery. I came back after a good day of sun to same draw and batteries down 15% in a day with no usage. Inverter off. Norcold refrigerator on propane.

Here’s what I’ve done

Restarted inverter

Reset inverter breaker (red switch streetside bed)

Power cycled batteries

Reset all AC breakers while watching amp load - nothing changed

pulled each DC fuse one at a time - no change

 checked all wire connections in dinette by pantry. No loose wires

Batteries are taking charge from generator but show same loss as soon as generator turned off.

Any ideas where to check next? 
 

Thanks in advance Oliver crew!

You should be getting +A from your solar. So 2-3 amps/battery, is say -8A total with everything off? You should be getting approx. +12A from your solar, given the fridge on LP. That means during the day your about net -20A. That's a large draw!

The one time this happened to us, I had the hot water heater on AC (electric). Are you certain no change with all the breakers OFF? You wrote you restarted the inverter. Did you leave the inverter OFF for a period of time to measure draw with it off? Do that to be sure it is not anything 120VAC provided by the inverter.

Hard to imagine anything DC taking that much power. Do you have any special DC accessories?

Also, pull your 30A jack fuses, one at a time. A jack could perhaps be shorted in a way where it's drawing power to ground through the motor. Do you have a fridge cooling fan or other fans? Battery heaters ON?

I cannot think of anything else DC that could draw so much amperage. Hope the best for you two! Bummer to have this worry when you're in such a beautiful place.
