I have a five year old Aqua Logic AQL-P-4 that has a one year old Hayward cell. I noticed the Check System light was on and the display had a message that read "Salt Generator Off Very Low Salt". I had the water tested and it was within range (3000) and the cell tested (it passed). Since I had the Cell Power issue two years ago and had to fix the cold solder joint, I decided to look at the PCB next. I noticed a slight dark streak near what I believe is a Power Relay and on the back side one of the solder joints for the Power Relay (top one) looks scorched.
I found some posts referncing the OMRON G8P-1C4P 24 VDC power relay needing to be replaced, but they referenced the Cell Power issue. Has anyone had the Very Low Salt message and a problem with the relay? Any guesses as to whether this may be just another bad solder joint, or does the relay definitely need to be replaced? One more question: the copper pathway near the bad/scorched joint is now exposed- probably about .25 inches. Assuming I replace the relay, how do I fix the exposed pathway, or is it even necessary? Sure hope I can fix this and save the $$$ that a new board will cost.
Thanks for the help!
