Wondering if dealer did any damage.
In 2017 when we bought our brand new Airstream TT, we had the dealer add the airstream 90 watt solar package. He did so, and we have been using it for the last 4 years. I am considering adding more so...

There should be a pos and neg terminal for the two array wires as the controller's input. Should be a pos and neg (not "ground|) terminal for the output wires from controller to battery (pos wire with a fuse near battery)
There might be a chassis ground wire normally not used with an Rv (stick house idea where they also ground the panels) Some controllers are "positive ground" instead of negative ground, which might be what you are looking at, don't know. In an RV where the chassis ground is not used, it doesn't matter which way the controller is--it only affects which path in the controller is switched (Mr Wiz has explained that)
If nothing bad happened in the last four years, no worries at this stage.
