radiators

Bluehealer,
After the radiator has been filled with water and left to stand for a while I think 24 hrs was a time span mentioned, you then earth the multimeter and dip the live end in the water, you should be aiming for less than 50 milliamps I think the figure was. Try all your accessories plus lights etc etc and see if the amperage changes, this came from the forum not long ago when I asked, you could do a search on stray currents and see what comes up, it wasn't that long ago. Hope this helps. Worked for me.Keep the shiny side up
