Do you think an automotive store would carry the 80 A main fuse? Or would I have to get that specifically from a Mazda dealership?

Also, how would I go about switching the fuse as you can't just pull it out..

 

there should be two screws holding the fuse in. I don't remember where it goes but you might be able to see it from the side or the bottom of the box. You can take the fuse box out to get to it if you are not able to get to it.

 

I got mine from Autozone or Advance Auto, I know they carry them. They look a little different, but serve the same purpose.

You can get to the bolts with the fuse box in the car. It makes it easier anyways because you don't have to hold the fuse box in place when using the wrench.

IIRC, there's 2 10mm bolts on one side, and 1 10mm bolt on the other side. There's little plastic "doors" you open up (slide down?) to see them. Mine are broken off so that's not a problem...
