Battery replacement gone wrong.
A neighbor friend of mine who is, or should I say was, a really good mechanic, offered to swap out the battery in my 2016 Stingray (non Z51). After installing the new battery and while tightening the negative terminal with his swivel head ratchet, the ratchet slipped out of his hand and contacted the positive battery terminal. It looked like someone had started an arc with a stick welder. Thankfully, I had lowered the windows before he disconnected the battery. Apparently, the doors locked when the battery was shorted out so I attempted to unlock the doors with the key fob but they didn't unlock, so I opened the driver side door with the emergency door release in the floorboard and entered the car with the key fob. The DIC did not light up and when I attempted to start the car the green light on the start switch turned yellow and the red light on top of the dash started flashing.. After disconnecting and reconnecting both battery terminals the red light on the dash did not come on but the the car still didn't recognize the key fob. The green light on the start switch still turns yellow and the park lights come on when I attempt to start the car. Does anyone have any idea what all could have been damaged when the battery was shorted out? Thanks in advance.

yeah would start at that.
stuff happens like that, definitely packs a punch for sure.
yeah i would start looking any any fuses close to the battery and go from there.
I would think there would be safe guards to prevent serious things from blowing up in case of direct short like that.
i would also recheck the battery voltage, possibly even charge it up some if u have a battery charger.
also ensure the small negative black wire wasnt damaged during install and ensure its bolted up as well.

So, you arc welded a tool across your battery terminals. In a perfect world, I'd hope the 350a fuse gave it's life to save your car from going toast and **** up.

Thanks to everyone that replied. It appears the 350 amp fuse is toast. It has 12.8 volts going into it and 1.2 volts coming out. That was the terminal the ratchet contacted when he dropped it.

BTW, you can buy those fuses VERY cheaply online. GM is very proud of that fuse and it comes as a package deal. I ordered 2 of those 350a fuses and have them in my electric goodies box in case I kill that fuse.

This is a replacement fuse. Snap off the old fuse, get this and bolt it in place.

I always make a habit of laying a towel over the battery working near tight space....or over the positive when clamping down changing battery.
