Well hope in this case just your main fuse. Easy mistake to happen if not paying attention though could cause so many issues. There should be 2 screws holding fuse from down below. If bad you should see burnt mark through filament in window. Make sure to disconnect battery before attempting to remove. Hopefully surge didn't go any further- keep your fingers crossed!
