Yes thats what I expected but I get something like 10000k between all pins as if the carbon track had broken and the wiper had fallen off. I have less resistance through my body if I hold a lead in each hand. Its very strange as it obviously worked fine previously and has not been physically damaged in any way or overwound.I cannot think what is wrong with it. When I get time I will open it up to see what happened.
