    Tried - they didn't answer that part of the question. Were good about some other stuff though.

    The other high demand is a fuel station pump... those draw a lot of amps....maybe you are hearing the fuel pump motor running, and mistaking it for that converter fan?
    I am also working on the fuel pump (was sitting too long and "seized" - varnish). Definitely not the the fuel pump. I took the cover of the area where the converter is and I can hear and feel the fan change speeds. Working on the light idea, although I really hope an LED is not drawing that much. Docking lights are a possibility - have to check that again.

    Score one for Flick and LBR,

    It was the rear docking lights. Incandescent and they make the draw, but I completely forgot they were there. Thanks all for the help. Always nice to know there is a source for help.

    Thanks again.
