Voltage in radiator water

Hi Jeff,
I fought this in my newly finished 97 S10 last year. I had about the same amount of voltage in the water with an anode. After pulling my hair out and finding a wet spot on the floor where it finally made a hole in the brand new Griffin radiator, I finally took a heavy ground wire with alligator clips and started testing grounds from everywhere. I finally found mine which was ground stud on wiring panel to the floor pan. I finally had no voltage in the water.

Prior, it didnt matter if I had the battery connected or not. I tried tap water, deionized water, water wetter, etc.

It needs a ground somewhere.
