Ok I have turned the main breaker off. With volt meter I plug the black into the dirt and touch the red to ground rod wire I get a reading of 5 volts. I can also touch the casing of a/c unit with red lead and get the same. Any ideas? Also inside breaker panel with main still off I'm getting continuity from the power side of all breakers to the neutral or ground. I was thinking this was normal because I had things turned on closing the circuit. But some that had continuity I know for a fact had everything turned off. Please give me your thoughts on this. Thank you!
