Have an aqualogic swg, new t cell 15, instant salt says 0000 ppm actual is 2700 or so. Also get very low salt error. Voltage at 30.81, amps at 0. Anyone have any ideas what could be wrong?
What does the average salt show?
The voltage is measured after the relay, so we know that the system is calling for production and closing the relay. Since the cell is new, we can assume that the cell, cord and plug are probably good.
Therefore, I think that there has to be a defect in the wiring from after the relay to the plug receiver.
You can check for voltage at the plug receiver. The top two connection points should measure the same voltage as displayed in diagnostics.
Putting your voltmeter leads on the top two points should show about 30 volts DC.
