Hello together, I didn’t know where to go with the thread. But think that it fits well here – otherwise please move. I wanted to clamp two W5W bulbs and branch 12V out of the fuse box for this. However, since I didn’t want to cut any cables, I decided to use a flat fuse picker:https://www.amazon.de/s?k=sicherheitsabgriffhttps://www.youtube.com/watch?v=uEzI4KFe3Jc&t=63s Now I had picked out a fuse, at which According to the operating instructions (in English) the 20A fuse is responsible for “Real Electrical Center Ignition”. Unfortunately, when wiring plus and mass of the cables I switched from the W5W bulbs, totally stupid… distracted by the telephone. So I connected the plus cable to the ground point of the car body and the ground cable to the fuse grip, switched on the ignition and then of course surprised me that the Lampc I didn’t work … so I saw my mistake and almost fell out of all the clouds. I assumed, of course, that it disassembled the fuse – which was not the case, however. But now there is suddenly no 12V left at the fuse slot. The vehicle starts without problems, no error messages are ejected and apparently everything still works the way it should on board. What did I shoot myself now? I get annoyed at my stupidity. t.
