    I have a customer whose irrigation zones nine and up won't turn on from the timer but they do if you manually open the valve. I switched a couple of the zones on the board to see if the board was faulty but it isn't, so far as I can tell. The zones all worked prior to the system being turned off for the winter.
    There are two valves whose solenoids I recently replaced in hopes that they would stop leaking but it seems that their diaphragms want replacing instead (one leaks, the other constantly runs unless it's clamped down all the way and the valve box is flooded).
    All of the wires appear sound and I can't find any evidence of tampering this time. The timer is a rainbird esp-24mc, any thoughts?

    if the valves are consecutive and share the same or branched common, one would begin checking the common at the last working valve and the first non-working valve.
    What are your resistance measurements?
    are either one or both of these solenoids amoung the non-working valves or maybe the last working valve?
    without some measurements you are asking us to speculate. normally consecutive non-working valves indicates common issues.

    this has, at the least, been educational.

    boots somehow always has the answer if one can decode it. direction by indirection.

    Unplug the battery and pull the plug on the controller. Let it sit for a couple of minutes then power it back up. If that doesn't work, verify the wiring using simple wire tests. I had a controller the other day that literally lost some valves .... power cycling fixed it, as it will for many controller related problems.

    This is a stupid suggestion. I hope you are joking.
