I have an Aqualink RS running my in-ground 17,500 gal pool system. DE filter pump stopped working. Polaris wouldn't run because filter wouldn't run. I tried switching out the circuit breaker at the pool (Had out-of-phase issues previously), but that didn't work. I tried replacing the filter pump relay, but that didn't work. Below is my Crayola diagram of the filter pump relay and subordinate Polaris relay. I still have a dead Post #2, even after replacing that relay. What puzzles me is how is power getting to Post #2 when Polaris is turned on?. Is my issue with Post #5? Is #5 drawing-out/shorting-out Post #2 when closed, but completes the circuit when open? Thanks in advance for your help.
