If you have changed caravans you may have a different plug set up but don’t worry there are a few options.
You could convert your car or caravan plug or you could get an adaptor.
This is a simple guide that hopefully will give you an insight into your caravan and tow car electrical systems. This guide has been written in response to some of the questions that have been asked on various forums.
It describes the electrical systems on a typical caravan and how they work. However, as caravans have evolved to the demands of the modern caravanner, these systems have become more complex, but a basic understanding of a simple system will help you diagnose faults even on complex systems in a modern caravan and help to maintain your caravan over the coming years. I have assumed you have no knowledge of caravan electrics, so I’ve started at the beginning and with a bit of history. Apologies to those reading that have some knowledge and find the early part a little simplistic.
I have described a generic car and caravan wiring system, it will not be identical to your car or caravan. Each caravan manufacturer will have adapted a basic system to allow for more features and to take into account more complex requirements from its customers.
