battery is dying overnight
if you're going dead in just a few hours, that is an enormous draw.
couple easy ways to check......test light between either battery cable, and its terminal. that much of a draw's gonna have it lit pretty bright. once you confirm that, unplug the alternator. all of its wires. if the light goes out, the alternators voltage regulator has failed. if not, move to the fuse blocks. pull 1 fuse at a time till the light goes out. that'll tell you the circuit that's drawing.
also, check your glovebox light, hood and hatch lights. make sure none of them are staying on.

picture of wire mod. I put my ground on the top tcs bolt. Its not loose and like a said i did this a few weeks ago without issue.
