2005 E350 5.4 gas engine, van previously professionally outfitted with a wheelchair lift, not sure if these battery terminals are Ford items:
The positive terminal won't tighten down to the post, the attaching nuts as tight as they can be but it can still be twisted without a huge effort. There should be no movement at all.
I'm looking to replace at least the positive terminal with something robust, has similar multiple supplemental wiring connections directly to the battery and would have an insulator or cover of some type.
Any help or direction where to find something would be helpful. I've checked a few high powered car audio supplies and Blue Sea Systems but nothing pops out at me.
