10 gallon water heater

Does anyone have a breakdown on the 10 gallon Suburban water heater. I think I have a bad element, but don't know where the element is.

Take the cover off the outside of the water heater, should be 2 elect. Wires going into the tank. Take them off, get a big socket to fit the hex nut part and unscrew it. Take to hardware, plumbing supply, home depot or etc. And replace, fill with water before turning power back on.
