Hi George.
An Idea to try, but you have lost me in the explanation.

Exactly where did you connect your earth wire to the system?

What is a multyway supply strip?
What is a technical Earth post?

I get the Idea of a steel stake driven into the ground. A hole drilled through the wall could make this permanent.
What is the Principle that all this earthing is based on?
What is the date?

Questions Questions?

Chris:)
