I have an older model Rain Dial we installed in 1992. One of the valves simply won't work and I'm stumped. I took a meter reading of the two wires going to the actuator and it measures between 12 and 13 volts with the actuator turned off. It measures almost zero with the actuator on. That seems correct to me. I put on a new valve with a new actuator and it still doesn't work. All the other 11 valves in the system work just fine. What am I missing?
