lawn sprinkler wiring
Okay; I do not own a sprinkler system, but have tinkered with a few, and I am sure that there are others here who have a lot of experience with them, but regardless, some details would help. Let's start with is this a new system, with, perhaps, a design problem, or is this an older system, that used to work as intended, and suddenly does not? Have you recently made any modifications, or replaced any components? Is the solenoid that allows water to flow to this zone when all of the zones are running the same solenoid that allows water to flow to this zone when it runs by itself? Have you checked your control panel for any loose or damaged wires? Since you have power to the system, and the zone itself works, I would focus on the controller, and the connections there, but provide some more specifics, and my bet would be on someone having the solution.
