    A diagram with the valve boxes and cable pathways might help some folks with a diagnosis.

    X2!...i'm still confused on the multi-strand, why there would be multiple multi-strand, unless i'm reading it wrong...

    Kiril has a great answer...my only question would be is this a new install that someone else did? because you would think the original installer would have at least had the system running before he left...and if it's not a new install, then why would the wires be switched? which would make you think that it's something else

    It is a very confusing situation to say the least. The multiple multistrand is not uncommon anywhere i have worked. Note that there were only 2 of the 3 commons used at the controller.

    Chief is on track but his number is off. Not a new install, prolly 70s/80s.
    Numerous repairs by numerous people would be a good reason.

    I did have a little edge as i located 3 valves last winter here.

    3,5,7,8 use one of the commons and the other valves use the second common. May have been a large obstacle and they had to horse shoe the system, or added zones at a later date. Usually instead of running two commons guys splice in at a valve box.

    The 14ga common was not colored differently and wired incorrectly.

    Remember there are 3 multistrand paths Tx. and i stated that only 2 were used at the controller. I found that the other was picked up in the field at a valve box.

    Com 1 = 5 & 6

    Com 2 = 4

    Com 3 = 3-7-8

    You were close, my first thought was 3-4-7-8
