that is a quick test kent, but it's not a SURE test of the glow plugs.
the only sure test is to actually remove the GP's and connect them to 12v and visually verify they heat at the tip and along the length of the element to a bright orange hot, and the tip should get nearly white hot.
if the .8ohm test passes, the next step is to verify voltage is reaching the plugs and the cabin light dims when the relay is lit.
