Its seems we are having issues with some zoned not turning on/off properly.
Digging into the Sprinkler Solenoid 'box', I see we have some Solenoids that have the common wire connected, but the 'control wire' is not connected (i.e. there is a wire connection cap at the end, but its not actually closing a circuit). My confusion is that zone turns on, but does not turn off. From what I can tell it was wired like this intentionally, which does not make sense. (it used to work up until this year) Any thoughts? can a solenoid function properly with only the 1 common wire connected?
