Rain Bird MV ERR

I keep getting a MV ERR on my controller, I replaced the MV AND selonoid and that didn't fix it. Any suggestions?

It's probably the wiring between the controller and the valve.

If you disconnect the wires from the solenoid do you still get the same ERR? I'm assuming yes.

If you disconnect the MV wire from the controller do you still get the ERR. I'm thinking no.

If both of those things happen then the wiring is crossed somewhere. Is there a spare wire running out to the MV?
