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...

With the panel in the sun put a voltmeter across the yellow and green wire ends to read Voc. If you get a voltage reading, the panel is working. confirm that by checking for amps.
If the meter does amps (10 amps max is usual) and if array Isc spec is under 10 amps (so won't blow meter fuse--or if no fuse fry the meter), you can switch the meter to amps and put it across the yellow and green ends and see if there are any amps as Isc. Or if no multimeter:
Connect the new controller to battery first to light up its display, then yellow and green into array pos and neg, and see if you get any solar amps.
