Question
My husband has been trying to re-wire our hunter pro c solenoid due to my pug chewing off all the wires. he was able to re-wire the front sprinklers (station 1%262)but for some reason he is having trouble with the back sprinklers (station 3%264). he replaced both the solenoid and bought all new wiring and wire connectors. He has tried many attempts to re-wire them, but isn't doing it right to work with the controller. We want to know what he should do, what wires go were and which color wire is the ground. Please help!

Answer
typically the wire that runs to every valve (called the "common wire") should be white. it leaves the controller (from the "c" post on the terminal block) and will go to the first valve. there it gets wired to one of the solenoid wires (doesn't matter which one) and then continues to the next valve in the same fashion. note that there will be 3 wires in that wire nut (one from controller, one for solenoid, and one to continue to the next valve) as will every valve until you get to the last one which will just have the common wire and one solenoid wire connected (the common wire does not have to loop back to the controller). so this is the "common wirepath" and I recommend you choose the white wire for it. basically the common(white) wire will be "daisy-chained" from the controller to all of the valves. if you have a group of valves in the front yard and a group in the back yard then run 2 separate white wires from the controller - one to front and one to back.

bear with me...

the other wire on each solenoid will get its own zone wire coming from the controller (labeled "1,2,3..." on the terminal block. so choose red for #1, green for #2, or whatever color you want. just make sure that if you choose the red wire for terminal #1 at the controller that you choose the red wire for the valve #1 in the yard. it is possible that you will have several of the same colors at the controller if your yard has more than one wirerun. now, IMPORTANT, if the wires have ever been cut and re-spliced anywhere on the circuit - make sure that the same colors are wired back together!!!

I hope you are still with me...

it is important to use waterproof wire connectors when doing this (they have gel or grease inside) and to use a pair of wire strippers.

I have a feeling this may be confusing. are you able to view an image file if I were to draw a picture and attach it - or is that necessary?
