We've got a Dethleffs Trend which we store on the drive. We've had it for only a year. Recently a couple of times, when I go out to check it, the 12v system has switched itself off & won't come back on using the rocker switch on the control panel.
If I attach shore, even for a few seconds, power 12v supply comes straight back & all is well.
I've had the 12v system cut off before while we've been in the van, I think it's caused by the voltage dropping to a threshold triggering the van to cut off the power (I was pumping the water through the hot water system). However, in that case the 12v was brought back online by just hitting the switch on the control panel.
The leisure battery still has over 90% capacity (recently fitted a Victron Smart Shunt) & looks okay.
The draw on the 12v system is barely a few watts (if that).
The leisure battery is a Varta Dual Purpose AGM.
Does anyone have an idea what causes this behaviour?
I don't mind so much the power cutting, it's the fact I can't get it back without shore power is the concern... Although I didn't try starting the engine - that may bring it back to life. Still, I'd like to know what's causing it.
Many Thanks!
