I have a Richdel Sprinker System (711) from the late 70's. There are 3 3/4" valves with two wires coming out of the top of each one. I had my yard cleaned up and when they raked it, they pulled some of the wires loose. I tried to put them back but it isn't working correctly. There are 2 stations, A and B, that water independently so I am not sure why there are three valves but they are all wired together. This might be too difficult to solve here but perhaps someone could give me directions. I put the loose wires back where I thought they might go but when I turn on the manual watering system, only the B station waters. I hear a click for the A station but no water comes out of the drippers. Maybe something else is wrong. I would like to fix this myself, if possible. Thanks everyone
