hello, just removed a drop ceiling and found wires above. one wire was a 12-2 and the other was either 10-3 or 12-3. bought extra wire for each spliced each one and connected each to seperate exposed junction boxes on wall. the 10-3 has power when i touch hot to ground and hot to nuetral. the 12-2 has no power now so both original outlets dont work. seems simple but i am at a loss. am i doing anything wrong?? thanx for your time!
