Had a zone decide to quit partway through its cycle this weekend, so dug into it today. Cleaned up wire connections (usual cause on this site), no dice. Grab meter and check voltage at controller, nada... Assumed bad station module so I replaced it, still no voltage.... Curiosity got to me, pulled station wire and voila, voltage. Went to solenoid and checked resistance, .3 ohm.... Shoulda checked that first!
