Used some jumper leads from the battery to the fan connector and the fan does not run off the battery.
Also changed both the lower and upper radiator hoses (Continental) and T-stat (195 AC Delco). That upper hose was a bear to reach and one would never be able to get it out with the cruise control box mounted on the frame. Had to move it out of the way.
Fan in question:
