If the cable connection at the battery was loose and/or the cable itself was too small for the load, that could go before the fuse. The fuse is supposed to be the weakest link, but if something else presents itself Murphy's Law comes into play.
Now that you are all fixed up, I recommend replacing the mega fuse. Even if it didn't blow before the other stuff, it still took a beating electrically.
