Hi, we've just had out first full week away with our 'new to us' van.
The van came with a brand new battery but we noticed towards the end of the week that it was dropping onto amber/red. When left overnight it went half way through amber but no higher.
Just drove back and thought the car it's fully charged again.
It seems a van fault and not a battery do you think? I thought about fuses but woud it not charge at all if the fuse had gone? Any ideas?
Thanks

dont know do you know anyone with a small tester that can check for you if the charger has failed.ie.a full battery should be 12.7 volts.a test meter can check this by touching the two battery terminals.connected to EHU the reading on charge would be 13.5 volts to 14 volts.check all fuses in the main 10 and 15 amp.its worth a check before you run out and buy a new charger.
------------- the only silly question is the one you do not ask.
This could be as simple as the battery terminals not being secured properly, especially if the suppliers overlooked this when fitting the 'new' battery. Possible too that the cables become loose from the battery terminals.
Was this a private supply or from a dealer?
Check over the wiring and have supply checked if you've access to a meter, as Michael's suggested.
We had exact the same problem 3 weeks ago for our fisrt trip out of the year, I had been chargeing the battery via the caravan from the house EHU every month or so over the winter. At the start of May left it on and got the fridge and freezer cold ready for the food and especially beer. When I come to move the van using the mover the battery was flat, I found that the 15amp fuse in the van had blown, thus not chargeing the battery but the volt meter read 13-14 volts.
I dont know about the battery chargeing via the car circuit but I doubt if it goes through the mains side of the battery charger.
How weird you should say that, hubby waid the same because we had trouble with the EHU during our stay, it was a low rating and you could only have one thing on at a time. That said, we turned everything off at night at it still only charged a little. We are bringing the van home for a few days to investigate further!
Thanks

Proberly a bad connection (corroded) somewhere.
You will need to check all the leads.
Start from the battery and work back.
Spade connectors need checking and cleaning.
Clean with emery cloth the battery lead connections.
It doesn't take much to bring a 12v battery down.
