I went to our caravan this weekend,and found that none of the interior lights worked.they are all 12v on this model.None of the fuses were tripped and all other 12v ancillories worked fine.Also the voltage meter didnt move when tested.Please can anyone shed some light on this problem for me.
What about your water pump and tv aerial booster (if fitted), and light in fridge (if fitted)? If none of these work check the charge of the leisure battery and the condition of the battery connection.
