Thank you. I have a multimeter but don't know how to use it. I plan to call someone that knows how to test my wiring in the morning. I have two separate ground boxes that zones run out of (two separate ground wires going into my control module). I moved the plug-in connectors around from the two separate ground wires and the control module is working fine. It seems my problem is with the ground wire leading to the one box that houses the 4 zones that don't work. I checked all connections in the ...
I have an 8 Zone Toro ECx Sprinkler System. Zones 1 -- 4 are not working. Zones 5 - 8 are working fine. I need some help on what I need to check to understand why they quit working. I checked the zone times and they are all set.
