Have a Tempo, but you can also use (3) 9V batteries hooked together if you just want to turn on selenoids. Turn one 9V battery up side down and hook it together with the other two 9V batteries by pressing the neg and pos posts together. Just touch the two wires from your selenoid to the positive and negative posts and your solenoid will activate.
I think what you are looking for to tell different wires in the ditch apart without stripping any insulation is called a wire tone generator. Google wire tone generator and you will see what I am talking about. It is a device you hook to one end of the wire and it puts a tone on that wire. Then you can go to your hole with a bundle of wires and find the one that has a tone on it with a special probe. Telephone companies use these all the time to find a single wire in a huge bundle of small wires. Greenlee/Tempo makes these also. They also sell these in the electrical section at Home Depot.
