selonoid/current common wire


Question
QUESTION: I checked all current to the 2 wires on the 4 selonoids in valve box and all was good, I then checked 1 selonoid wire with white common wire and only 1 selonoid had current, I also checked all colored wires with common wire in controll box and all good, - I am a bit confused does that mean I need to replace the 3 selonoids without common wire current in valve box??  This all stems from my AC symbol  and  short in system.

ANSWER: Hey Jenelle, you are only going to get a current reading on one solenoid, because this is the only zone turned on.  Turn on another zone/valve and this next solenoid should get a current reading. Just turn on one valve at a time, and see what valves work, and what valves do not work, and this will tell you what valve to check( the valve(s) that do not work).It's a matter of trial and error. Good luck and have a great day.

QUESTION: I do not understand what you mean by turn on another valve/zone, if I do that water sprays everywhere(meaning I turn selonoid head manually with hand)??? And yes they all work when I turn with hand.  All the selonoid wires are connected to one common wire in valve box.  Am I to dissconnect wires in controller and check that way??

ANSWER: Hey Jenelle, when I say turn on another zone, I mean by the controller. How are you checking for current, are you not turning on the valve/zone by the controller? You need to turn on one zone at a time (by the controller) and check each solenoid one at a time to see if you are getting current to all the solenoids from the controller. The reason only one colored wire shows a good reading with the common wire, is because this is the only valve turned on by the controller. Each solenoid will have one wire that hooks to the white common wire. Then the other wire from each solenoid will be hooked to a separate hot wire (colored wire). For instance zone #1 red wire, zone #2 blue wire, zone #3 green wire etc. I'm not sure what your problem is, are you still getting the AC symbol. Let me know what you find out, good luck and have a good day.

QUESTION: I can not just turn one zone on at a time since the common wire and that set of wires in controller are knocking me off  all cycles(manuel, three minute test, regular program), and giving me the no AC symbol. I can disconnect the one common wire(bad one) to the front set of four and the rear set of zones runs by itself with the other common wire. I also checked current in the "bad" section and the green wire does not pick up current.

Answer
Hey Jenelle, Hook up the common wire to the bad set of valves, but then disconnect the 4 other hot wires from the terminal in back of the controller. Now hook one hot wire up to the terminal at a time, and see what happens when you turn on that particular valve. Lets say you hook up the red wire and turn it on and it runs okay, but you hook up the blue wire and it shorts out, go to the valve with the blue wire, and replace the solenoid on this valve. Good luck and let me know how you turn out. Thanks and have a great day.
