I am not crazy. Well I am, but not about this. I was messing in my sump and I put my hand in the sump water and I felt a steady electrical current. I have a grounding probe in my sump and one in the display. I checked the display and couldn't feel a charge there. I went back to the sump and while my hand was in the water I unplugged the probe and the charge stopped. I plugged it back in and the charge started again. Is this normal? Really weird thing is, I was just in there yesterday and didn't feel a thing.
