1st post here. Seems to be a very smart crowd!

Hoping to get some advice on fixing my 11 station system. I picked up two yellow lab pups whose idea of chew toys were the valve covers in the back yard and the wiring from the solenoids on top of the valves. I checked the system and noticed that two of the stations in the back yard weren't kicking on but the timer showed them running. I replaced the solenoids and still the same thing. I did notice I could twist the solenoids and that got the pop-ups working. Any clue as to what else I should be looking at?

Thanks in advance for the assist!
