You could also just stick a battery back there, then wire the fridge up directly to it- bypass everything. Sometimes it's easier to diagnose if you can see the whole circuit in front of you..
I think you're on the right track with the ground though, just pull the cig plug out, pop off that ground wire, then run something completely separate to what you know is a solid ground. If that fixes it, then do it again but more prettier.
