    On a commercial property, the controller is 200' away. There is a 2' electronic valve. It will not open electronicly. I know the timer is working fine, but not the velve. I can open it manually, so i am assuming there is a wire problem. The wire runs under a drivway. Where do I start?

    You may need a locator. I like mine, a Pro-Tech 600 that I got from

    The PEI/ Tempo 521 or 521 A are other possibilities.

    They cost a little more, but some guys find them on ebay.

    Sometimes you can rent one. Or hire someone who has some experience to do it.
    I don't think it's a really steep learning curve though.

    BTW, you did check the wire connections and the solenoid resistance, right?

    Had a tricky locate today... 16 zones and only 4 working...... Used the 521 and traced the path under a road then followed with the ground fault the fun part, the ground fault was showing a fault under a road, in a sleeve..... pulled on the wire and is was still taped a new common under the road and now all 16 zones working...

    What size wire would you run to pull in THAT solenoid?
