Chances are it isn't a ground if that happens. What I suggest doing is this. Disconnect the ground wire from the battery. Remove the power distribution box where you noticed a potential problem. Turn it over and check for corrosion, damage, or wiring that appears loose. I think you found the source of the problem. Now you just need to narrow it down to the exact location.
NOTE: When you loosten the box, be careful not to damage any of the wiring. Also, pay attention for wires that may have melted the plastic around where the wire enters the box.
Let me know what you find.
