Aqualogic SWG Board Failed?

[Nikoletta]

Hello, I am wondering if you have found a solution. My aqua logic is doing the same thing. It is an older system so no way to tell which relay is related to what polarity. We removed board and saw some burn marks on the K2 relay. We re soldered, worked for a couple of days and then back to 0amps, 0 salinity, 31V when on negative polarity. Positive polarity readings are all fine. Cell has only been used for 1 season (maybe 5 months). I remove it over the winter and replace with dummy cell.

Moved from here.

Sometimes the solder fix can loosen up. Inspect the solder joint once more and maybe even refloat the joint. Look for splits in the copper trace on the board.

If that doesn't work, you can always replace that relay and see if it solves the problem

BTW, both relays (K2 & K3) are responsible for swapping polarity.

Thank you. We will attempt to do that this weekend. What I still find odd is that the check light has not come on. My reading for my salt jumped from 3400 average to 3800. So I checked instant salt on both polarities and noticed that on negative polarity it was reading 31V, 0A and 0000PPM. I adjusted my % output for now to help.
