I did a test this morning. In a bowl of tap water
(chlorinated) the reading was about 0.7 Ohms at a
6" separation of the probes. That is a lot more
conductive that the readings I got, and will
quantify on the next visit. Pure water is
considered dielectric,but also shows some
conductivity.

Test resistance only on disconnected wiring, measure resistant to ground
either side of the switching point. . The controller will likely be a open
collector that will measure current to ground. Do nor use megger, you are
not testing insulation.

Is there a way to test the conductivity sensors for the low water
shutoff and restart on a submersible well pump, from the
surface? Could the wires be resistivity tested?
What should the resistance readings be between the wires? Would a
megohm meter be the right tool to use? Could the pump b
