You need a multimeter, and check for resistance between any of the white with black stripe wires (ground circuit) and a know good ground. You should be getting 'infinite' ohms, meaning no resistance. Zero ohms means a break somewhere, and anything else means a corroded ground connection somewhere causing a resistance.
