Are you sure you are hooking the cable to the right battery posts? Main fuse will blow if you hook em up backwards.

Ok so the first replacement battery worked, but the posts were on the wrong side? Second battery has a problem with blowing the main fuse? Try a known good battery, with the right specs for your car.
