    The common isn't 'bleeding back' like you think it is

    you really need to ohm out your valves from the controller

    What is it like 75% of electrical diagnosing is done from the controller. At least it tells you what needs to be done next

    It skipped the blinker fluid cap is loose.

    you really haven't given enough of the right information to allow anyone to help you, voltage measurements aren't enough. as mentioned, you need to isolate and "pair" each common wire with the valve wires that they service. while you are doing that, document the resistance measurements for each zone. the probability of zones 1-2-3-4-5-7-7-8-9-11-13-14 being on the same common is high but not absolute until verified.

    you need to do some more work before anyone here can be of help

    you still haven't supplied enough information


    you seem to be locked onto a bad solenoid train of thought "How can I locate which solenoid is bad without checking all 11 that are not working??" so you already have eliminated other paths and tunneled your vision. no wonder your noggin hurts.

    start fresh, bring all of the measurements of the wiring and solenoids to the table, check your voltages in parallel and "under load" for accuracy, current is measured in amps or milliamps and in series. resistance is measured in ohms and megohms for the best results. try a short to earth test of each zone wire and their common for insulation from the earth.

    in order to receive any help here you are going to have to do your homework.

    BTW: i have found that you can tell if you have a bad splice in a water filled box by simply turning the zone on and sticking your hand in the water

    or stand by the water-filled box in your bare feet and take a wizz into the box :eek:

    I'm missing something, as per me. Has the OP proved the clock yet? :dizzy:

    i don't think the op is a shooter, when he gets to 10 posts he can pm me for a guide to his troubleshooting issues though. i spent an hour typing up some suggestions last evening. :waving:
