I have a 2010 Ford fusion with the 3.0L engine with the same exact problem, and that was the same problem on my car also. The wiring connector right by the battery like you described was rubbing against a metal part on the vehicle. Thanks for the video It must be a design flaw. Wrapped it up and tape and that will fix the problem. Thanks 👍🙂👍
