    Just got a 2008 Autocruise Gleneagle yesterday and have just connected to the mains. The fridge works and the power management panel shows mains charge going to both leisure and vehicle battery. I have yet to delve in detail into the handbook for the power management system but seem to remember charging all the batteries on the vehicle was an emergency mode and not to be used often. Can anyone help on this subject please?
    ALSO a fan like noise is coming from around where the vehicle battery is located under the passenger floor. Got the plastic cover off but there are some bolts holding a metal plate over where the battery is so gave up in the heat today.
    I am assuming there is a cooling fan for the battery under there which goes off when I turn off the mains connection.
    Any help on this one please?

    cant help with the charging question but i cant see the battery being fan cooled.
    many batteries are in a sealed compartment and arent cooled.

    possibly the previous owner fitted an inverter, if so it needs finding and switching off as they draw battery power even when not in use.

    another possibility is a supplementary fan in the outside fridge vent.....noise can play tricks and appear to come from where it isnt, if you follow my meaning.

    Many chargers have fan cooling.

    also some but not all onboard chargers have fans built in to protect the charger from overheating.

    as for charging batteries, it is typical to leave the charger on to maintain battery condition and charge whilst plugged in. if you leave the van standing any length of time without charging, you will soon find the batteries flat and potentially damaged due to being too deeply discharged

    Many thanks

    I suspect the charger may be under the floor hence the fan noise..it is very hot weather! There are two leisure batteries not far away under the centre of the habitation floor so it would be logical to put the charger near there
    It is not the fridge as it is way at the other end of the van. It sounded initially a bit like the radio when off tune...hiss/white noise.
    The floor cover will come off tomorrow, lets hope the previous owner stored his dodgy cash under there.
