Yup, it was the rain detector! Disconnected the wires, all OK. Thanks for all the help.
Yep, infinite Ω on all four zones. BTW, why is there one more wire than the number of zone valves? Now do I have to dig up the wire?
How do I do this when the controller is far from the valves? E.g., to check the continuity of the common (my prime suspect) do I need a long wire or what?
Don't have a spare. Can't I do this with a meter?
I have a Hunter SRC Plus system with four zones. I cannot run any zones from the controller, auto or manually, since hurricane Irene (we didn't get hit hard here in eastern massachusetts). I opened each zone valve manually at the valve; they work fine. The controller also appears to be fine, display, etc., but I reset it anyway. System still won't run. I assume the transformer's ok, since it runs the controller (no 9v battery is installed). Where do I go next? Thanks, BH
