i have a welding machine remote control with a potentiometer and a 110/120 volt outlet in it.coming off of the aluminum housing box there is what i think is a diode,its between the box and the 110v ground wire. the markings on it are as follows: red,green,black and maroon.what is the purpose of this and how and where do i purchase one,and what do i ask for.bear in mind i have a limited knowledge of electronics.
thanks!
thanks!
