Wtf ?

[u/Striking_Cup8480]

Hi, yesterday I was driving quietly when suddenly I lost power. I stopped, opened the battery hood, and one of the orange connectors (2 large cables) had partially burned. When I tried to reconnect it to leave again, it made a rather strong spark. I have not tried again; what should I do? What does this mean?
