I own a 1991 Mazda Miata and unfortunately I haven't been able to drive it for the past six or so months. It's just been sitting. I tried to start it but it was completely dead. I tried to jump start it, still completely dead. The very first time I tried to jump start it, I stupidly reversed polarities (stupid gray cover instead of a red one). I bought a new battery, but that didn't solve any problem as the car is still completely dead. This has me thinking that I blew a fuse. What part do I need and where is it located? Is there a way to check what I need to do before going to the dealership for the part?

 

I don't know where on the Miata the fuse box is, but I'd venture a guess and say its either in the engine bay or near the opening of your driver side door near your feet. There should be two. I would look at those first, let us know what you came across.
