Tach together, After standing longer (about half a year) I removed and charged my battery these days. Just installed and pushed to the door to start the old times, ignition key turned, Christmas tree normal, starter actuated, Christmas tree off. My first reaction was to check the fuse, which is ok. Second thought short circuit in the system, so I removed the battery again and packed it to the charger, and see there, battery empty. Do you have an idea or guess where I’ve spent a whole Saturday finding an electronic error and don’t try to repeat it. Thank you very much for all the approaches Benni
