I would start at the controller, measure resistance of each solenoid write them down and then check them at the valves, you could have a bad wire splice buried someplace or some bad wiring what kind of site is it?

Ever since i replaced the box i loose stations by the week and am down to 2 working now. I tested with a multimeter at each valve and the all have power. I am going to start replacing salenoids next week. WHAT ELSE AM I DOING WRONG? OR IS THERE SOMETHING ELSE I NEED TO CHECK?
