Replacing controllor with same colored wires
I bought this house a few years and the sprinkler system worked. It had a richdel 446pr timer with 6 zones and I could get 6 zones by playing with it. The controller quit working and I bought a rain bird 6-zone to replace. No zones were labeled in the richdel. I have the rainbird mounted and power to it, But I have only 5 wires. 1 white ( which I figure is the common) and 4 red wires. There are a couple of zones that I cannot get on and 1 zone comes on with 3 seperate zones. How do I figure out which wire goes where?
