Hiring one is too expensive and the only one I could "befriend" is the one who did the ground modification. He called it "Cheating the neutral." As far as the ground rod, Thats what I thought. As far as I know, When the house was built in the early '70's, (1970 I think.) They used a water pipe as the ground. I don't see any ground rod(s) by the service panal or meter. I'll work on getting him to check it out this weekend or next. But lets move on to the other issues. AC and DC "flirting". How can DC use the AC for return ground and DC grounds conduct 120VAC with no shorts in either system.
