Car has no power. Alternator and battery were changed last summer.
Ford Mustang 2005 GT 45000 miles
We regularly drive our 2005 Mustang GT Convertible. For a few years, we have had issues with the convertible top going up and down.

We brought it to another Ford dealership, and they told us that the alternator was not providing enough power to put the convertible top up and down. We had the alternator and battery replaced. Brought the car home, and it didn't go up. By chance, I replaced the 10 amp fuse for the convertible… Read complete

This seems like a bad ground or something in alt to battery wiring. Have seen this with a over charging issue after someone doing a big 3 wiring upgrade and didn't have it done correctly. When car over charges it will go nuts all lights go out while driving everything stops working electronically in car but car would stay running. I'd look at the wiring as starting point.

CommentReverse 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
