Fundamentals of Grounding

Like water returning electrons always follow the path of least resistance. The electrons follow areas of higher moisture and mineral content.
Soil is not a good conductor. Dry, frozen, or non-conductive soils can cause your earth return system to become less effective. Check for poor connections at the ground rods caused by oxidation or corrosion.
The ground bed for your charger is much like an antenna for a radio or television. The larger the antenna, the better wave collector it is and the better reception you get on a TV or radio. The ground bed works in the same way, only it collects returning electrons from the soil.
