has a broken field wire been ruled out?
Here's what he said in the email. The fact the valve wont turn off after he turns it on manually makes me think it's the diaphragm.
I am stumped. I've worked on my sprinkler systems for years, so I have done a lot of trouble shooting. Right now, I have a Champion valve, electric solenoid but the valve does not turn on. I had to disconnect wiring, and after hooking it back up wrong, one of the two valves non longer worked. Figured my mis-wiring, while corrected and properly working with 2nd valve, no longer worked with first valve (right next to it in manifold) So I purchased a new solenoid, and re-connected all wiring, correctly as per instructions. BUT same problem un-changed. What I do is turn zone on manually at timer. Nothing. Then I turn valve on manually at solenoid. It works fine so valve is not plugged. But then only way to turn it off is to screw down on shut off screw. So what could problem be?

I'm assuming he turned off the controller. Who knows.
