When I run manually, none of the zones work. My system is setup with a master valve on zone 1 that comes on with each zone (just like the manual wiring shows). The master valve appears to be working fine. I tested this by opening the small valves on my back flow valve to check that water shoots out when I turn on any zone. I tested the voltage on the controller zones (terminals) and all zones read 0 Volts AC (between common and the zone terminal) when off and 27 V AC when I turn on any zone. I would expect all zones except for the Master Valve (zone 1) and the zone I am testing to read 0 V AC. However this is not the case. For example when I turn on my first zone (Zone 2), the voltage between common and terminal 1 reads 27 V AC (this is the master valve - Zone 1). The voltage between common and terminal 2 (Zone 2) reads 27 V AC as expected (however, nothing happens in the yard). Voltage between common and all other terminals is also 27 V AC which shouldn't be the case. Can someone please help with troubleshooting this as the system worked perfectly fine for an entire year. Thanks.
