New battery install, then nothing works.

[Gowjer]

I recently picked up the 2015 Hyundai Genesis coupe and upon arrival, I had some repairs done. I I noticed the battery was low. I replaced it and now nothing works, is in "not a damn thing!"

Why-how the hell did this occur?
I'm at a loss, so far I've:
Checked all fuses.
Checked factory ground, and cleaned it.
Cleaned all battery connections.
Traced power into first fuse box where I've got power up into the B+ and fuel pump. After this, there's no power whatsoever, lmao, I'm f**ked!
