a multimeter set to VAC to check for voltage across COM and the station that is on is how you test the unit is switching.
did you have your system winterized? have you gone through opened all the valves and turned the water back on? It takes a several mins to refill my lines every spring before enough pressure builds to push the heads up and theres several valves that need opened and a few that need closed.. just booting the sprinkler back up in the spring usually isint enough.
