To start I am no irrigation expert at all period.... But I have a customer that has a Rain Bird Rotary System. He says it is shorted out and will not work. That is all he has told me, I haven't tested it or anything. If its just a cut or chewed up wire I can fix that but if its really complicated I won't touch it. Anyone have any clue on what might have shorted out or what might cause it?, and how much to charge and if I need to be licensed?
