Okay the past 2 mornings I've come out to a dead battery in the truck and I'm gonna head out in a few minutes to test for a draw but not sure if I need to disconnect both batteries (since it's a diesel) or just the positive off one.
It's a 2003 GMC Duramax and I'm hoping someone will be able to let me know soon so I don't end up getting a bad result.
Thanks,
Kevin
