I rechecked the outside switch the correct way by grounding to water heater and I do have power. From there I have no power to black wire at element. From the diagram above I would have to assume that my t'stat is bad even though it is not burned thru. Should I replace that next?
So with switch closed do you have 120V AC at top t-stat and then at bottom t-stat (black wire)....and did you push the button on top t-stat to reset it?

Notice the connecting wire is burnt thru on 120V AC side
IF High temp t-stat (top) needs reset then normal t-stat (bottom) is suspect...should open at 130*F
If it doesn't then high opens at 170*F shutting down all heating until manual reset
Replace t-stat set.
