hi, i am currently having a problem and can't seem to get any assistance. at our football field the sprinkler system stopped working. all 9 valves are showing a fault. checked the fuse, tried to reset system, still no go. all the faults come back and the system is not working. any ideas on how to trouble shout this? i am assuming their is 1 common power or ground that is causing fault but have no idea where to start. need help asap as the grass is turning brown already
