SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

Hello Everyone,



Great forum! I've got a bit of an odd one here.



I was running my sprinklers and everything was working fine, then suddenly poof the water shut off and the heads retracted. I went to the timer and it was still calling for water. I checked the voltage on to the zone that's currently on and got a 26VAC. Tried having the timer fire other zones, no sucess.



Here's where it gets a bit odd for me. I check the other zones that are not currently being called, and I'm seeing 26VAC to each of them as well. I pull the power to the timer and begin continuity checks, no shorts from common to any zone. I pull the wires to all four zones from the timer and check them against each other for continuity. I was a bit supprised to find contunity (~56 ohms) between each of the four zones.



Before I begin digging up the back yard, I wanted to see if anyone could explain if I've misunderstood or overlooked something in my troubleshooting.



Note: around 2 years ago I did rewire the valves for a similar problem, and it ended up being a broken common wire. However this time is different because I'm not sure how I could be seeing continuity between each of the four wires that go to four different solenoids.



Any help would be appreciated! Feel free to e-mail.
