Alright this has been bugging me for a bit now, been trying to trouble shoot for a couple months but electrical is not my strongest area. Had my car sitting for about a month while I was traveling and I came back to a dead battery, no big deal, but ever since then every time I shut my car off it is completely drained the second the ignition switches. I already replaced the battery and that worked for a whole day, then right back to the same issue. I replaced the alternator less than two years ago, but I do hear a slight whine while accelerating. Another note, the person who owned the car before me did install an aftermarket radio, and if I’m having a parasitic draw that’s my best guess, but in the 4 years I’ve owned this car it has never been an issue. Anything helps, thank you!
