1999 Swift Corniche 15/2e fault on 12v system

Fanheater, radio, main interior lights and aerialpack not working on 12v system mains. 240 power working. Any idea what problem is?



It could be the in-line fuse that has blown and needs replacing. A 12V circuit is protected from an overload situation by an in-line fuse which is connected to the feed coming from the battery's positive terminal. It is normally located close to the battery but should be inside your caravan. If you locate the positive feed from your battery to inside your caravan, you should find the in-line fuse holder. Once you have found the holder, change the fuse and see if that works.
