Sorry for the beginner question. I am trying to test the wiring between the controller and the control valves. As i understand I need to check the resistance after disconnecting the common wire and the station specific power wire. What should the resistance reading be assuming wiring is good and solenoids are good?
Off the top of my head, I don't recall exact numbers, but it should be something on the order of 20ish to 50ish ohms when testing across the common and a single control wire.
