ttt for peace of mind.

I figure any fuse will do it's job when it comes to a short. In my case It won't be pulling all that much current so I won't be exceeding what the wires rated for.

Thanks. I'm pretty sure I was running the same 140a fuse when I was temp running 4awg years ago but wasn't sure. It's been a while.
