You must use a car battery and a volt meter.Take the
battery out of your car and attach a cable to the positive
and negative terminals.Try and start your car,if it doesn't
start that means you have correctly removed the
battery.Stick one end of the positive cable in the
ground,the deeper the better,dig a hole with a shovel if
you have to.Stick the negative cable in the ground at
exactly 38.6390 inches away from the positive cable,this
measurement is extremely important.Now,wait 3 hours and
measure the voltage in the ground between the two cables.A
voltage of 7.75 volts dc or higher indicates proper ground
resistance of .00672 ohms.A lower voltage reading indicates
that the ground resistance is too high.Saturate the area
with water and wait overnight.Take your readings again the
next day and see if they have changed.This is a very
accurate method and it has worked for me every time.
