Sorry if this one has been asked before but I couldn't find symptoms like mine. We are going away at the end of the week in our 2008 Elddis Crusader and I went to the storage site to fit a new fully charged 110ah battery. The van is not on EHU so I wanted to check the 12 volt electrics. Everything seemed to work at first but then I noticed that the battery charge display meter (CBE) was flickering i.e. on/off. The flickering was constant and seemed to coincide with a sort of clicking noise form the under locker fuse panel.

I then lost the 12 volt altogether so I checked and ultimately replaced all the blade fuses but with no effect. Checked for loose connections and anything else I could think of. I have read that it could be the battery charger, power supply unit or even a fuse in the positive supply cable to the battery (which I can't find). I wondered if the clicking noise was relays behind the fuse panel. If so are they repairable?

I can't get my dealer out to look at the van until we get back back so my main question is this. Can I get 12 volt electrics i.e lights etc when I go on EHU on site i.e. bypassing the 12 volt from the leisure battery.

Thanks in anticipation.

Yes the pos/neg lugs on battery are different sizes but I will make sure I have a good connection.

have you double checked to make sure the battery is fully charged, they really do sound like dead battery symptoms.

Failing that, it may be the habitation relay thats failed (thats clicking on/off)

Hi Timtheenchanter do you mean the power supply unit. Replaced battery with a fresh one reading 12.8 volts, checked the battery charger on mains reading 13+ volts, replaced all fuses. Does this mean the PSU has gone awol?

depending on what control panel you have (if you could post a pic/give model number) some have a relay that switches over to the battery.

if its failed, it may click on/off giving the symptoms you mention.

Similar thing happened to my van it was the charger/PSU in the end. I took it to bits and found there was a black area on the PCB and one of the resisters was loose. I resoldered and has been fine since.
