which fuse are you referring to? The DC-DC converter is supposed to output 200A (not sure if that's continuous) and definitely does not have a 50A fuse, I've drawn 120A from it already. I'm talking about a model 3.
I'm not sure which car you're talking about and where the nose cone connector goes to, but if it's the 12V battery, forget it, don't do that.
