Well my truck is wanting to die.
After monkeying around for 6 hours on it I did the following:
Found my jumper cables, broke into my own truck (yes I used a coat hanger a ****huge knife and a bastard file to do so), recharged the battery off a borrowed hilux, replaced the cigarette lighter fuse (also the reader port fuse too), found no engine codes in the memory, cleaned a ton of corrosion that wasn't there yesterday off the positive post, took it to two different shops and all but stripped off the insulation off the battery cabling, and replaced my map lights because one of them died between yesterday and today.
Seriously, most of the corrosion in panel 4 was not there yesterday. Especially the orange stuff.
Anyway to save the charge for tomorrow morning I pulled the cables off the posts for the night.
I'm speculating here but there's probably a duckton of corrosion into the cabling and yesterday with the hotter than normal temps leaving me running the AC that basically pulled enough draw that everything went wonky and ducked everything up and it started corroding faster and drained the battery overnight.
Additionally, when I hit it up with a multimeter it was reading as 1.91v before I charged it.
