I've got a main fuse that does NOT want to come out (you know, the 120 amp one, I believe).. all the others come out fine, but the main one, um.. no.. just seems like it's got some sort of lock on it, but I can't figure it out for the life of me.

 

Found it... stupid idea whoever designed this crap..

This is on the driver's side shock tower. All of these fuses are available from any parts store, they're not special Mazda parts. If one blows, check to find out why it blew before replacing, and always replace with a fuse of the same rating, never higher or lower. The "main" fuse is different - it's bolted into the fuse block, unlike the others that simply pull out. To remove the main fuse, unbolt the fuse block and open the two "doors" on either side of the fuse block to reveal the bolts. Undo the bolts and remove. If you short hot power to ground while working on the car (like having a screwdriver touch the alternator's main terminal and ground), this fuse will blow.

 

Do not just turn the 2 bolts, remove them completely and the fuse will come out easy easy . Remove the bolts you will see why .

 

done it, got it out, found a new 120 amp at Pep (Rice) Boys

Now the car won't start though.. I think it has something to do with the Code Alarm security system.. grrr
