My neightbor has a lawn sprinkler system using a Rain Dial
controller. The controller won't turn on any of the five valves.
I switch the controller to Run/Manual, swtich to a specific
valve, put run time that valve and hit the Manual start button.
Instead of turning on that valve, I get a flashing OFF. According
to the manual this indicates the solenoid is shorted or there is
some other electrical problem.



Problem for me occurred on an Irritrol KwikDial KD9-INT -- flickering
display + when turned to OFF, a flickering OFF on the display. Another
person in this forum replaced the big power supply capacitor on the
electronic board (in my case the board was labeled 102-2057 Rev B
22639561) which fixed the problem. Did the same thing on the KD9 -- i.e.
the C4 220uf/35v capacitor was replaced and the problem was fixed.

Did you try to unplug the power? A Power surge can temporarily corrupt
the EPROM on the unit.
