Reverse polarity

Ford Mustang 2002 Gt 4.6 300000 miles
Made a mistake a hooked the battery terminals in reverse. Pretty sure I friend my alternator but now the car gets no power even with a fully charged battery. And I’m now getting a spark out of my ground side terminal when trying to jump start.

I hope your issue got resolved, if not, check for a big fuse next to tge terminal, usually its of a high amperage (probably 80 amps). Afterwards, check on the fuse box in the engine bay, then in the cabin. Replace any blown fuses and your car will hopefully start
