Verlauf von "Sparks and Horn while Jump Starting" bearbeiten

You accidentally have the cables crossed. A honking horn and lots of sparks are classic symptoms.  Red goes to positive, green to ground. The positive post is also the larger one.

Now, hopefully you didn't burn out any fuses... or the multifuse. If needed, check for power on both sides of the fuses (ingoing and outgoing).
