No. I'm saying if you disconnect the wires directly at the valve, run the cycle, nothing happens (no watering, no chattering, no controller disconnecting from wifi) you can pretty much guarantee it is the valve.
Once you finish above experiment (to eliminate wiring shorts as a possible problem), then you can turn off your water, remove the solenoid, connect it to the wires and see if it chatters outside of the valve (it likely will).
It most cases, it's pretty easy to twist out the solenoid (turn off the water to the sprinklers first) and replace it. Just bring it to store and find a match. Helps to bring a picture of the valve as well.
