Rainbird Controller, 3 stations only, recently wiring was disconnected to replace siding, then reconnected back to the controller. 1 & 3 work 2 is not, this is a sectin that fixed copper heads and pipes from the pvc base pipe. I have dug down to 3 pipes close to where wires connect to the controller all seems okay but no solenoids here, not sure what I should find with copper pipes! Thanks in advance. John
