There was a habitation check a couple of weeks ago and nothing was flagged.
We have a simple setup - single habitation battery with solar panel and Schaudt controller. It has always behaved.
A couple of days before we left home the Truma boiler safety drain opened and emptied the system. I reset and refilled.
We set out on this trip ten days or so ago and everything worked overnight on hookup and without for three nights. We stayed over with a friend with van parked outside and found on preparing to leave the water system had drained and the 12V system had switched itself off.
The battery was sometimes registering a -50A drain, at other times it was fine. Given that the battery was about six years old I thought a change might be in order, having scanned various articles on the web. I did wonder if the control panel was having a fit.
I reset refilled and bought a new habitation battery on the way to the next stop. The water system drained as we drove off the battery dealership forecourt. I fitted the new battery and we had two nights off grid with no problems. I took the precaution of jamming the drain valve shut, reasoning that frost damage is unlikely this week.
We are on hookup at the moment and have a steady 13.9V reading on the habitation battery with an apparent 50V drain. I unplugged and we have exactly the same reading.
I am concerned that when we are off grid again (tonight for several nights at least) things will go pear-shaped.
Can anyone tell me what is likely to be going on here? I have not found direct references this issue on the web and electrical systems and I are not the greatest chums.
