Advice and views please from those who probably know more than me.
Put my Autosleeper Worcester/Winchcombe into our no mains hook up storage after 3 weeks in Normandy, both batteries in tip top condition.
After another 3 weeks in storage, went to retrieve for a few days watery break and everything is dead, both batteries show around 5 volts across terminals on my multi-meter.
Extracted and charged up vehicle battery and it was just under 13 volts in 24 hours or so, started vehicle checked alternator charge, all OK at 14+volts and back to home drive. Leisure battery had benefited also by the short journey and was at 7.5 volts now.
So much head scratching at what could have led to both batteries severally discharging after just 3 weeks.
But when I switched on my Sargent EC400 control panel and selected water tap on, the pump kicked into life and wouldn't shut off even though the taps were all shut. Adjusted the Whale pressure switch and all is now OK, off and on as it should.
So I am hoping this is the source of my battery discharge, I must have left the control panel tap switch on and the pump activated, although I am usually careful about not doing that.
So my query is (if you are still with me) if the pump kicked in yes it would flatten the leisure battery, but is there a link to the van battery so it flattened that as well?
Or is there something else that could have caused the discharge?
