Not sure what the wattage of the element is. But a 1200 watt element should have about 10 ohms resistance. A 1500 watt element should have about 12.5 ohms. So sounds like your element is good.

If you are measuring 115 volts at the screw on the element, then the thermostat and hi temp cutouts must be OK otherwise there would be no voltage there.

But curious. You say you measured 115 vac between both heating element (you said anode) terminals and "ground". What did you use for ground? Frame? If so that may point to the problem. A meter would measure 115 vac from the hot terminal to the frame. But there should be zero volts from the ground terminal to frame. A problem that has been reported more than once on here was a bad neutral (loose wire) in the junction box on the back side of the water heater. And that would show the same voltage measurement problem you are seeing if measuring to frame.
