    Measure the resistance between the common and each station wire.

    1 or OL means that the circuit is open.

    20 - 60 is a good measurement.

    Under 10 is usually a short.

    Check the common at the valve to see if your #2 valve is actually the first in the ground. A bad splice could be the culpret.

    my initial thought was the clock, 0 time on zones 1 and 3, or like someone else said, it could be on a different program...sometimes these very simple issues are overlooked

    I was just thinking and remembered a startup I did earlier this year on a system, 3 zones with a Pro-c. The controller had a problem with zone 1. I unplugged the controller and unlocked the zone module and blew it out and put it back in and the controller as far as I know has been working fine. Not sure if that helps.

    Does the system has a master valve? If so is the pump setting turned on on 1 and 3?

    Without knowing whether the field wiring is intact all else is moot.

    1) wire path
    2) solenoid
    3) controller
    4) hydraulics

    That's the order i use but with few variations, i do make sure the water is either on or off, depending.

    Great idea Boss. While at it, one can perform the simple resistance measurements to tell whether one has continuity or not.

    Found the problem in all of 30 minutes! Have been thinking on it all week and when the pro 700 arrived, I ran straight to the clients home. Found the common was cut right in half. For some reason it went to zone 2 first and then back out to 1 and 3. Is that a common occurance? No pun intended
