New trisensor wiring is good. I had my pool company come out to diagnose the continuing issue. Naively I thought they would be checking various voltages, amperage, ohms, you know, electrical stuff. What I got was cleaning my pump basket filter, cleaning the cell, and running test mode......high volts low amps...need new cell. Really, that's the in depth diagnosis? Not that I disagree with the conclusion but I wanted more "testing" since I ran all the same tests and still had questions. Oh well. I'll be chatting with the company owner. Anyway, I just bought a new cell for about $370 with a rebate. We'll see.....my own approach to diagnosis is to swap out stuff and test.
