Connected this sprinkler solenoid to a different zone and it works as it should – solenoid turns on.
When you did the test with a different zone, you used same wires from the solenoid to the controller?
If answer yes: I don’t have enough knowledge to answer.
If answer no: The wires between controller to solenoid are shot, I had a similar case and I tested like you did but I tested also the wires and turn out to be the wires I had to re-route.
