I didn’t exactly catch a lead of the tank at the front of the tank when the tank was pushed down, so it came to a short circuit with the battery. It got a bit of smoke up and the fuse no. 5 engine was through. Starting did not work even after replacement of the 15Ampere fuse. That then also burned again. I have not examined anything further. What could the problem be? R850R with ABS BJ 1996
