It would help to know what car (make, model, year). You probably melted some fuse links (wires that act as fuses). You may have also done much damage to the electronics.

I agree with checking the fusible link. It looks like a wire and goes from the battery + terminal to a relay box under the hood. If it’s blown the insulation should be bubbled, but check it with a meter anyway.

If that’s the culprit DO NOT replace it with anything other than the proper replacement fusible link. A regular wire will not offer any protection, and they do vary between different cars in their cuurrent carrying capacity.
