Place the two electrodes together to observe the meter reading. Indications of successful charging: After 12 to 48 hours of charging there should be some particles of silver oxide on the bottom of the container. The water should have a metallic taste after 24 – 48 hours. If not, then continue for another 12-24 hours At first, with distilled water, the meter will show very little current as an indicator of water conductivity. If there is no meter reading when physically shorting the two electrodes together, this suggests a disconnection inside the generator and we would repair this without charge. All of our generators are tested well before shipping, so the above problem is unlikely.
