I did a dumb thing...

Rob,
I wasn't referring that the loud pop was the fuse blowing.If you were able to crank the engine by jumping it before you should still be able to get a reaction when you try to jump it again. I say check the easiest thing first if you've got no power and that would be the main fuse.If that's good keep checking. Just a starting point.
I've blown a few fuses while trying to use automotive jumper cables on a tiny Dream battery.
