This was a cross threaded and thus not tight 12v connection on my brand new car last year.  The bit thats missing is a melted, but not blown, 200amp fuse and the other post.  About two minutes away from the plastic catching fire when we found the problem.  

 

 

 

Linky no worky!!

Bad connections don't blow fuses, they just get hot. As I said a bad chock block on a water pump got hot enough to melt the plastic and burn my finger. The owner thought it was the pump smelling which of course wasn't working properly.

Same with the pics I posted, a bad connection got very hot but it didn't blow the fuse.

The nut holding the dark blue cable is only on by about one thread as well.

 

I can see that potentially being an issue if vibration loosened the nut, but other than that it's not the threads that make the electrical connection is it? I thought it was the ring terminal face to whatever is underneath it, in this case another nut.
