Using a multimeter, measure the resistance between various possible ground locations, such as between

the ground of a junction box (outlet) and the ground of a power tap, between the ground of a junction

box and a metal water pipe, between the chassis and the ground of a power tap, and between the chassis

and the ground of a junction box. A good ground connection should read between 0.0 and 0.5 Ohm.
