Loss of 12 v systems
Hello Everyone. I have a 2008 Fleetwood Heritage which I have just brought out of winter storage and cannot get power to the 12v systems unless I plug the van into the car. I have checked the leisure battery (2 years old) and it's indicator shows it is
charged but I have also checked each cell with a hydrometer which confirms it too. the van is fairly high tech and has a control panel, solar panel, central heating system, alarms etc. I am aware of the control panel freezing which I know how to resolve
and have also changed a small 3v battery on the back of this unit for good measure without any effect. On the odd occasion I have managed to get the 12v system on for a short period via the control panel it says that the habitation battery is low and on
discharge. I have also checked all the 12v fuses and connections and am now at a loss as to what else the problem could be other than perhaps a relay but this is now stretching my knowledge. Can anyone offer any advice as I would prefer to understand and
resolve the problem myself?
