I have a hunter controller. About 15 years old. During the last scheduled run no water came out of any zones. The controller counted down fine. I have reset the controller without success. I have swapped the controller with a new one same results. I checked the wires at the controller; basically when a zone is active, all the wires have voltage. I compared that withy neighbor who has the exact controller and when his is running in one zone only that zone has voltage.

What does that mean? Is my controller bad? Or is there a problem on the wiring? I do not have any wires in the MV slot. Only AC and G, C and 1-6 have color coded wires.

Any help will be appreciated. Thanks.

Get a multimeter and check the system wiring.

I did. It shows voltage going to all 6 zones even though only zone 1 or zone 2 is active. Same test using multimeter on my neighbors controller shows voltage only on the active zone.

Thanks.
