Urgent help needed please
Problem with Avondale Dart 525-4 2007. I'm no expert so I will explain the problem as best I can. We are meant to be going away in the morning. We collected our van from storage and brought it back to the house. Now to start with, I'm very confident that out leisure battery is knackered and has been that way since we bought the van. We always use the van when hooked up to electric so the battery has never caused us an issue.
I plugged the van into the elec socket in our garage and all seemed well. Lights, heaters all checked and seemed to be working fine. Also the fridge was starting to cool down so all good.
We have a "Battery condition" gauge on the wall and when hooked up to elec, this always points to the green section of the gauge. I left the van plugged in for a couple of hours and then noticed that the gauge had dropped to half. I looked at the RCD unit and noticed that the light on top had gone off and one of the MCB switches had tripped. I reset the MCB and switched the RDC unit back on. The light on the top came back on and all looked like it was back working. However gradually over the next hour i noticed that the light in the van started to dim until gradually not working at all. Also the radio is not switching on. I have checked that elec is still coming to the van as I can still use sockets to charge phone.
Does this sound serious?? I was wondering if replacing the leisure would help but I thought that when plugged in to the mains I was bypassing the battery.
Any help would be appreciated.
