First off, please try to write in sentences. It is hard to read the way you are writing. Thanks.
If the main line coming into the house is metallic you must connect to this pipe within ' of where it enters the house. This wire originates at the neutral/ground bar of your service. You would typically use a #4cu for 200A and #8cu for 100A.
The reason your tester works is because these grounding electrode wires have NOTHING to do with grounding the circuits in your house. This is a different thing entirely.
A circuit "ground" comes from the neutral to ground bond in your main panel in the form of a neutral bonding jumper which is installed when the service is installed.
