We see all sorts of 12 volt setups. Especially as more and more people add circuits to their caravans. Some are ok but others are not. No labels, no fuses, wrong cable or poorly crimped cable lugs just to name a few. We do all sorts of wiring repairs from new earth points to a full fit out of new items. Tidy up existing poorly installed items or repair a faulty light circuit. Contact us to talk about your issue.
