PCBelarge,
Thanks for your interest. I went through the house and turned on everything I could find. Then I ran a 50' extension cord in from the main to provide me with a ground for testing. I could get no current from the plumbing.
The wiring has no grounding conductor.
One way I will prove if it is coming from within the house or coming in on the water pipe, I will move the water bond from the back of the house to the front instead, where the water main enters the house. This will give any incoming current a low resistance path around to the main neutral instead of thru the house plumbing.
Then if the issue still occurs, I will know it is internal.
I still need to check out that neighboring house, did you read my post about the neutral current there that didn't add up?
