Hello, Sicherung 6 MB Sprinter Bj 2000 for turn signals, windscreen wipers, fans, burn through. When replacing the securing and running of windscreen wipers, warning turn signals, windscreen washing system Ignition is one, everything seems normal, fuse holds. If you drive a piece with the car, the fuse burns several times with turn signals and windscreen wipers. The 20 fuse comes from the accessories. The 20A bought yesterday from MB seems to be significantly bigger, thicker, which actually can’t be. 20A are 20A (?) The master at MB thought it could be due to the battery or/and the trailer coupling. This is a little difficult for me to understand before because it is normal in the state. The (brand) battery has been changed recently and about 13V at engine run about 14. I had assumed in the direction of LIMA controller, but this was rejected because the measured voltage seems nromal. Until now I could not see if a Bosch or the French factory is in place. We did not have a switch plan or workshop book.
