CI Carioca 644
Exp
Since 1980
My 2005 CI Carioca has lost all electrical supply on the domestic side - no 12 volt fridge, no lights, no water pump etc. I have checked fuses on the control unit circuit board and all ok. I have unplugged supply plugs to the board and found 12.7 volts coming from both leisure/house battery and engine battery. I have checked for loose connections or poor contact but nothing obvious was found.
I have been told by a CI dealer that it is not uncommon for the main circuit board to fail and so suspect this is the problem. A replacement costing £300 takes 6 weeks to come from Italy!
Anyone have any other ideas; know where to get a circuit board tested and repaired; buy new or second hand; replace with alternative; etc?

not familiar with your van/electrics but on mine domestic electrics cut out when ignition turned on could be the relay that controls that operation?

you don't say how long you have owned the van, if not long then its possible its just a switch problem. !2v fridge should only work when the engine is running and will only maintain the temp not cool it down.
Again possibly a switch problem, failing that a fuse near the battery.
Last resort is circuit board, does power reach it?

There is a big Red switch by the passenger seat / door, is that fully on?

electrics failed

Take a look at the MCEA web site and get a local engineer out to help you. It could be a faulty PCB but it could be many other things.
