This morning I went out to start my truck and found the batteries where deader than a doornail. Is there a chance the V2 could kill the batteries when plugged in for about 36 hours? I'm kinda doubting it. That's the only thing that was plugged in, but I know that the batteries where getting weak (I couldn't even get a full read of my TCM without it bombing), so I suspect that it was just their time. Just want to make sure so I don't accidentally murder my new redtops by leaving the V2 plugge in for the weekend.
