Thanks. I am able to get water by turning on each station individually at the valve. I guess I'll go buy an ohm meter. To check between the two wires are you referring to the white wire that goes into the slot labeled "com" on the controller and then a wire to any of the stations?
I had an ESP-8Si that I thought had died this spring when it wouldn't start up. I bought an ESP-8TM from Sprinkler Warehouse. They have the same wire connections, faceplate virtually identical. However when I connected the new one, sprinklers still don't come on. Does anyone know if these are exactly interchangeable and if so, what else should I troubleshoot. Thanks.
