I have since been told that all the plug sockets will work without main switch on when the caravan is plugged into the mains. I didnt realize this before. The lights are all on 12v system which explains them. Im new to electrics so didnt realize how it all worked. Just cant figure out why fuse has burnt out. Problematic battery? Or something else as it didnt just blow.
This is unbelievable !!!!!
First of all, taking this comment " I have since been told that all the plug sockets will work without main switch on when the caravan is plugged into the mains"
What monkey has told you that????????? The main 230v sockets will NOT work with the main RCD in the Off position,,,,,,,,why for safety !!!!!!
Then taking this " Im new to electrics so didnt realize how it all worked. Just cant figure out why fuse has burnt out"
Simple answer, you have made a major mistake which could have set the van on fire and has now got you into a position of needing the whole system checked as you cannot see what damage has been done to wiring all along its length,,,,,and that is going to be expensive and very time consuming,
Then this " Problematic battery? Or something else "
The battery was fine, the problem is YOU!!!!
And this " It was an auto electrician that sussed the lights for me"
Since when was an auto electrician versed in caravan wiring, which is completely different to a car as a caravan does not use the chassis as the return .
My view now as a caravan engineer is that you have made your van potentially a lethal item as a lot of the wiring is suspect but cannot be inspected as it runs behind various panels .
If you don't know what you are doing, DO NOT TOUCH IT !!!!!!!!
