Put the meter between the negative battery post and the bonding wire. Got no voltage and no milliamps. Put the meter between the negative battery post and the quadrant got the same third of a volt and 33 milliamps going from the battery to the quadrant (?), and that is with all of the other negative leads taken off the post. I have a full keel boat with the rudder attached to the keel, so it has a lower gudgeon. Zinc today is two weeks old. The one previous to this one lasted only three weeks before I needed to replace it. I'm diving on it later today, but I'll bet it needs replacing again. Boat hasn't changed. Only thing different is that we got some new neighbors at the dock. I don't get why I would get a positive flow from the negative battery post to the quadrant.
