Measured from the water tank metal, I expect to have 0 volts on one terminal, and a negative voltage from maybe -300mv to -1500mv. I will be interested in what you measure.
I have various notes. Powered Anode, Shielded,.118 Diameter X 31.5
SKU: 100111286 AO Smith is the longest I have seen for that. I think a longer anode is good in a highboy water heater.
I find it confusing as to what is just the electrode, what is just the power supply, and what is a combination. Here are my current notes, and I would like to see what you find:
