Left key on, dead bat, jump doesn't work
I left the key in the on position this morning and killed my battery (I'm assuming). Had to leave it at work because a jump from my buddy didn't work. No dash lights when hooked up to the cables.
I'm going back to pick it up after I hook up the trailer, but was hoping someone could give me a clue what gives here before I left to go get it. Or, just give me a clue because I gotta fix it when I get it back home.
Thanks for any help. Probably wrong place to post, but best chance of being seen.
