Hi. I have a 2003 ranger edge with the 3.0l flex fuel v6.

Something seems to be drawing power out of the battery while the truck is off. A co-worker of my mom has a 2005 ranger and he had a simmular issue with his truck about a year ago. He said something was grounding his positive cable. Not sure if this is a common issue for these or not but i'm going to assume I have the same issue. If it is a common issue can someone point me in the direction of where it could be grounding out.

Pretty sure the alternator is good.

Thanks for imput.
