my vehicle outputs 14.4V when its first been started... now if there's significant current at the trailer jack, the wiring resistance drops the voltage. meanwhile, the Parallax DC converter is(was) trying to output 13.6V or so to charge the
battery... depending on the design of the Parallax's output stage, this *could* back bias its output transistors and dump a bunch of current into them.
Its also quite possible the parallax just picked that
dry camping weekend trip to die. I'll never know, its in the ejunk bin at the local recyclers.
