Hi everyone, just wondered if anyone has had the same problem as me and got it sorted. I've had the motorhome parked in the driveway for over a week hooked up to mains. During that time the van battery & both leisure batteries have run down to virtually no charge. Mains is connected, charger light is on, and shows charging on the control panel. I first noticed the problem 2 weeks ago when the van wouldn't start after being parked on a DA meet for 2 nights & I had to get a jump start, although by the time we got home the batteries were charged. Anyone any ideas?

I've just been back in the van, charger had switched to charging leisure batteries from van battery which is what should happen when van battery is fully charged. I switched charger off, leisure battery showing 10V van battery showing 0V on control panel. Switchedcharger back on to van battery for half hour then switched back to leisure battery. Put multi-meter on van battery after disconnecting & that shows 11V but won't start van so I've started charging with my car battery charger & I'll check again later.

Van battery now charged enough to start & showing 14.3V with engine running, leisure battery showing 13.3V. Turn off engine van battery showing 12.7V, leisure battery showing 12.2V. Switch on ehu with charger van battery still shows 12.7V, leisure battery shows 12.2V. Does this mean charger not working?

A bit late to come in here, but what is the present status of this problem?  First reading suggests to me that the starter battery has gone high resistance either internally or externally. This would result in automatic charger sensing the starter battery as fully charged when it isn't, and switching over to the leisure one.  Chances are the starter battery has gone dry in one or more cells.  If so you may or may not be able to bring it back to life - depends on how bad it got!  There is no substitute for regular battery maintenance - including replenishing electrolyte before levels drop below plate tops, and checking specific gravity of electrolyte in each cell for variations between cells in the same battery.

I'd be intereted to know what the outcome here was.

Guy.
