Tom,
   The only stumper I have had similar to yours was a wind turbine feeding to 
the controller with good voltage.  Turned out I was reading the DC Voltage 
with actual earth as the return path.  The negative wire was unhooked and the 
wind turbine had been connected to earth ground instead of the negative wire 
back to the wind controller.  Not much current flows through 300' of earth.  I 
can't quite figure an exact parallel to your situation but thought I would throw 
it out anyway.
