"No Cell Power" simple solution worked like a charm! Exactly as show on the step by step instruction video, burn mark was at exact location. Made the repair as shown and back up and running! Hi all - seems like problem is universal. Lots of posts and traced back to May 2009 but not able to find what the 'solution' actually is regarding this relay. I have same Hayward Goldline Aqua Rite with t-15 cell and it is only 7months old. Same problem - no flow light then zilch. Can someone please guide me to the 'solution' in these posts? or another web site? Gratefully yours and cheers. Moh No Cell Power was the problem. I was ready to go buy a new T-15 Cell after cleaning the original and no luck. I did a little research, found your site and followed the instructions. It took about 20 minutes and solved the problem. I hope the new solder holds up, but so far so good. Thank you for the advice and savings. It fells good to keep my money and not give it away for such a common problem and easy fix. Shame on you Hayward!!!!!
