I have a 2007 Lunar Quaser 525. It is stored at home so today I went out to see if everything was ok I should add at the end of the summer ( I fitted a new battery ).which I have had on charge for the last three days.In the van nothing is working no lghts no radio absolutely nothing.Am I missing something such as a master swich ? I dont want to take it to the dealers if its just something that I should be able to rectivy myself.
