I was jumping the car battery, and got the plus/minus crossed. When I turned the car on, nothing happened. I checked the fuse box but I don’t see anything blown. I think I need to check the main fuse, but I don’t know where that is. Can you tell me where to find the main fuse?

Hello,

In the diagrams down below I have included the wiring diagram for your vehicle's Starting Circuit (with the fuses and their location highlighted for you) and the location, diagrams, and callouts for your vehicle's fuse panels. Please go through this information and get back to us with what you are able to find out.

Thanks,
Alex

Welcome to 2CarPros.

There really isn't a main fuse, but there is a 100 amp fuse that powers several things. Take a look at picture 1.

Also, does anything work?
