Yesterday I replaced my battery. The place I got the battery from put the wrong battery in twice and connected my battery backwards. Someone that had my car before me thought it would be clever to use the red wire as a negative. No idea why but thats besides the point! We spend about 2 and a half hours checking all the fuses. We finally came to this fuse on the side of the fuse box that appeared to be the master fuse. We found out that it was indeed blown. So we made the connection between the broken fuse and twisted it together just so my car would run. I want to get this taken care of ASAP does anyone know exactly what this piece is called and also where I can get it for the best price? Thanks alot!

 

Call autozone, its a 120A main fuse
