The other day I was feeling a tingle in a small cut on my finger when I put my hand in the water.. I just tested the water 3 ways with the volt meter. Red in the water of course. And the black in all 3 prongs. Start with the ground... No reading. Then in the small prong I'm getting 100v.. And in the big prong I'm reading 14.4.. I do not have a gfci plug.. But everything is plugged into a surge protector 60$ home entertainment center extension .. With out the red in the water. The small prong was getting readings.. I am electrical illiterate !! In the big prong. Everything unplugged and plugged in one at a time. The volts slowly go up. 3v to 5v to 7v.. All the way up to my last power head. It ends up being 14.4. An I doing anything wrong? Do I need to do it differently?
