Hello everyone! 1st post, hope someone can help - we bought a very old caravan a few weeks ago and I need some help with the electrics. I can't afford to pay anyone to do it and it really isn't important enough anyway, but I get the feeling it wouldn't take much for me to get it going if only I knew how!
The mains hook up connection works absolutely fine, as does the running lights from the car (brakes, indicators etc).
The only thing that I have yet to get working is the 12v system.
The previous owner said that although it had recently been redone (this does seem correct as the mains and running lights are all new) they had always had hook up and had never used it and didn't really know how.
The original grey plug on the caravan had been left to drag whilst towing so needed replacing, but before I replaced it I charged the leisure battery up and also hooked up the knackered plug to the car just to see if anything happened. This got some of the 12v lights working.
I have since replaced the grey plug but am unsure if I have done this correctly as I understand the wiring standard changed a few years ago but it the van was built in 84 so I'm not sure which wiring diagram to follow.
Also, the leisure battery is knackered and doesn't hold a charge. Now even when connected to the car nothing on the 12v system works. Does this mean the the 12v system will not function even when connected to the car if the battery itself is dead?
Can anyone give me any pointers?
I could even take some photo's of the wiring set up if this would help.
Cheers in advance
