    Just gone to MH and begin the spring opening and found the battery was absolutely flat....no lights on dash.

    I'm guessing I have left something on? If I flick the switch to cab will it help me start it?

    Thanks

    Probably not
    I suspect that switch is to charge cab batt when on hook up
    Americans have a switch to join up hab and cab batts in an emergency, not seen anything like that on a Euro Van

    just opening up the van after the winter lay off will probably mean it has been stood for at least 5 months.

    your battery will have both self discharged and been drained by 'parasytic' loads...alarm.clock etc.

    a good chance after 5 months it may be knackered due to being left flat for so long.

    Unless, you have a twin battery Transit Geo!
    As soon as the ign is switched on, all our batteries are joined via an isolator under the driver's seat.
    I know this won't help in this case, but I thought I would share the info!:thumb:

    Hi Derek sounds like you have killed your starter battery :Doh::cry: You could try jump leads from the L/B or even connect it onto the van to get you started.Then drive to the spares shop and buy a new starter battery- remember to disconnect it next yr and take it home for a charge before fitting :Wink:

    Derek...It seems that is the norm....Flat batteries after a winter storage...but I must say the motorhome we have now is much different to our last motorhome...meaning... we had the same size solar panel fitted from new 120w...same size Fiat battery on the cab...same Fiat 130 - 2.3 multijet.....but the difference with this one... the solar is charging the cab and hab batteries.....and the other motorhome must not have been charging the cab battery...because every time I use to try start the other motor after a few weeks in the winter period the cab batt was flat ...sometimes I could not even open the door with the central locking key fob......totally flat... due what is running in the background ...immobilser etc......On the new motorhome the hab and cab battery are always fully charged even though the same things are running on the cab background....must be wired different or a different regulator....Both set ups were fitted by a different motorhome companies:BigGrin::BigGrin:...and that is not using any EHU:thumb::thumb:

    AS I said many times my battery was totally FLAT...so it was either buy a new battery or try one of these smart chargers...(cranking batteries in France are around 180 to 250 euros) so it was worth a try I paid about £59.00 for mine...it worked for me the old battery back to normal....I mean like a new battery again and I still have the charger for other batteries.

    I don't know how bad your battery is ...But this charger worked for me...

    http://www.ebay.co.uk/itm/Ring-Smar..._CarParts_SM&hash=item5191f635a5#ht_506wt_828

    looks like they have gone up in price since I purchased mine.....You do not have to disconnect any wires off the battery....it does not damage any thing and after about 6 to 8 hours all back to normal .it pulses then chargers at 16amp then drops down.....BRILL I should COCO

    Much prefer the manual system on the yanks, you know when its needed
    I suspect ith a fully automatic system its possible o have a knacked stsrter battery without knowing till you get on site, and wonder why your leisure has bee pulled down
    Is there a monitoring system for all batteries
    if so Im talking bull:Doh:

    Our starter battery is charged by the solar, though leisure batteries have priority. I don't know how this works, but it does, something in the Rapido electric box of tricks.

    Update

    OK....so I tried to jump start it....that didn't happen:Sad:.....so I took the battery out and found it was a Magneti Marelli....so my guess is its original.:Eeek:

    Have now bought (but not yet fitted) a new battery.:BigGrin:

    My only worry is what caused the failure? I did find that I had left the fridge switches on....but as far as I am aware when not on hook-up or ignition on those switches have no effect?

    Never mind, lesson learned,:Doh: next year I will disconnect when I put her up for the winter.

    On the plus side there was absolutely no smell of damp in her and I discovered that I have an Alco chassis extension so I should be able to make my own towbar easily.:thumb:

    I left the fridge on once off hook up and flattened the battery, on mine you can leave the door ajar to allow a bit of air circulation what I didn't realise is that it was enough for the light in the fridge to be on, hence a flat batt. ain't dun that again.

    fiats

    When we first got our Fiat the engine battery was flat after being left for 6 weeks, (unlike our previous Merc Sprinter which never went flat on us) apparently Fiats have a reputation for the alarm system, internal clock being quite power hungry.
    All of which will drain your engine battery unless you have something like the Battery Master fitted which will keep the engine battery topped up whilst the leisure batteries are being charged.
    Of course you need either a solar panel or to be plugged into the mains.

    Usually from my understanding the fridge won`t run on 12v unless the engine is running and this would be from the leisure batteries as is the cab radio.

    This is almost certainly true if you have a three way fridge but definitely untrue if you have a 12V compressor fridge as this will work all the time, engine on or engine off.

    A compressor fridge is great for use on board ferries as it works efficiently all the time but does cane the habitation battery. A hookup, genny or solar panel with extra habitation batteries are needed.

    Mine is the same - it uses a Battery Master - quite expensive but easy to fit.

    The battery master trickle charges the cab battery once the habitation battery is fully charged. Worked well all winter when used with my solar panels.

    Last year we left our Autotrail Comanche for about a month and all 3 batteries were flat as pancakes. Dealer thought one leisure battery went down so charge no kept and starter battery never charged.
    This year, after new leisure battery and new starter battery fitted,after a month stored with solar panel active, all three batteries dead again. Dealer said other leisure battery went down taking others with it. Both leisure batteries again replaced (at dealers expense) Our dealers (Elite motorhomes) are very good but while looking around their yard while they carried out the replacements we saw the new Scout and the new one is due in May! :thumb:
