Did you have 240 volts? I had the same problem at the weekend on my Xplore, turned out to be a loose conection to the charging unit, but check the fuse first if its ok and if you feel capable of doing it ENSURE THE 240V CABLE IS DISCONECTED, disconect the battery on my van the charger is at the back of the consumer unit and swithches on automatically, undo the screws that hold the wooden frame it sits in,4 screws that hold the plastic unit together and the charger sits in a silver box at the top, the main cable on mine at least resembled a "scart" plug, what a feeling when you get when you check that and it pushes in, loosly put it back together ensure no one is near the unit and no bare wires etc, switch on a 12v light and plug in the 240 volts you should have 12 volts even without the battery being connected, if not then its a new unit which is a "plug and play". DISCONECT THE 240V CABLE again, on our last Compass the unit was seperate from the consumer unit principle is the same ensuring that the 240v cable is disconnected
