Automatic sprinkler system no longer works after brownouts
After a series of brownouts last year, my automatic sprinkler system stopped working. The sprinkler controller's display had shut off. The system itself still worked if I manually opened the solenoids by turning them counter-clockwise.
I thought the controller had been fried, so I bought a new Rain Bird controller (similar in model to what was previously installed) to test with. Before disconnecting the wires from the previous controller, I took a picture so I could hook up the wires in the same order/color to the new controller.
With the wires snugly attached to the new controller in the same order as they had been connected to the previous controller, I programmed the controller to start watering Zone 1. Nothing. I tried manually watering all 4 of my zones using the Water Zone Now feature on the controller. Again, nothing.
I returned the new controller and hooked up the wires to the old controller, which I had discovered just needed to be reset. I can still program that controller just fine. Aside from when I swapped out the controllers, I haven't adjusted the wiring since I bought the house a few years ago. I certainly haven't touched the wiring in the valve control box out in the yard.
Is the likely culprit a set of four fried solenoids?
Any help or suggestions would be greatly appreciated!
