Fix prior jimmy-rigged repair job

Prior repair job had spliced the terminal block wires with electrical tape; electrical tape caught fire while making pasta.

anyways, disconnect all power, remove burners, pull stove out. you'll need a 1/4" drive socket to get the back cover off; six bolts total. phillips head screw driver to unscrew the terminal blocks; replace with new terminal blocks; it did not seem to matter which wire plugged into the back. put everything back together. very easy.
