I'm in the process of a complete nut and bolt rotisserie restoration / resurrection of a 1965 MGB. When I go back in with the electrical system I want to go with a single battery 12 volt negative earth system. Electrics are not my strong suit! I know some of the gauges will need to be converted, and I'm sure other electrical components will probably also need converted. I've just started doing research trying to find any checklists, or technical document outlining the requirements or best way to attack this conversion. Any help would be greatly appreciated. Thanks!
