that does not mean the white is grounded, although it should be frame grounded someplace near the converter
and AC voltage doesn't have a positive
it has a hot and a neutral, which is an arbitrary designation
because it takes both wires to complete the "alternating current" circuit
I'm an electrical engineer, so I'm well aware of the nomenclature as well as the difference between AC and DC. However, "hot" and "ground" are terms often used when referring to 12vdc automotive (and RV) systems, so that's why I used them. In any case, my point was simply that while black wires are most often associated with "negative" on automotive 12v systems, that may not be the case in an RV. Someone more familiar with autos could easily assume that the white wire in an RV light fixture is the + lead and the black the - lead, and since LEDs, unlike incandescent, are polarity specific...
