Hi there, hope someone can help. Got a small problem with the 12v sockets in my recently purchased camper. When hooked up to the mains via the Zig CF9 everything works OK except for the 12v sockets. They're the 240v/12v combination type with the 12v socket in the middle with the aerial and satellite connectors. Having burnt out two 12v devices in as many minutes I'm assuming I'm getting 240v through the sockets instead of 12v. I Haven't checked with a meter but it couldn't be anything else, I'm sure. What I want to know is: is there a step-down transformer built into the Zig reducing 240v to 12v or should the 12v sockets be wired directly to the leisure battery? When I'm not hooked up to the mains nothing comes through the 12v sockets. I'm just curious as to how anyone could have wired this up wrong or if the zig is at fault. Thanks in advance.
