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.
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?
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.
