My SWG shows no lights at all. I reset the system and sometimes the lights come on blink then suddenly go out. I opened up the pentair easy touch panel and looked for a fuse but there isnt one. The SWG is pluged into the panel and then the cable goes directly to a circuit board hooked to a circuit breaker. When I put the system in Maintenance mode the lights flicker then go off like they should. When I put the system back into normal mode the lights flick on then go off for good. Its getting power so thats not it. Is the cell bad?
