SPRINKLER TALK FORUM - You Got Questions, We've Got Answers

I'm green at DIY Controller/Valve/Wiring, and trying to speed up my learning curve so I can figure out my problems.

I have a Toro Vision II Plus controller that won't run about half my zones, but runs the other half fine (detailed problem in Controllers, Sensors, & Remotes forum). I'm told that I need a new timer/controller box, but I'm not completely convinced. If I open the bleeder valve on the zones that won't run by the Controller, they work and run the zone for as long as I leave the bleeder open just a little and shut down a few minutes after I close the bleeder completely. Is this information "telling" of anything in particular? I figured that the controller would either work, so far as operating the zones goes, or not work, but maybe I'm wrong about that? Can someone tell me the next best step, or send me to a location here on the website that will 'splain it to me? I'm looking around, but I think I'm greener than most here, and need to back up a few steps, maybe, so I can find my bearings.

Thanks.

Thanks. I'll check that as soon as it's light tomorrow. I did a quick "look and feel" on the wires, but didn't check water-tight connections. I'm not sure I know how to do that -- and the valve boxes fill with water when the system runs (like when I let the bleeder drip today while it ran manually), or in rain. BTW, I keeping wondering if my controller is wired right, too. Nearly every year at start-up time, Zone 3 (one that doesn't work) would be quirky about starting, so whoever was working on it would comment that something was wired wrong and change the wiring in the controller box. I don't know if was the same change going back and forth, or every change was altogether new, but it happened quite a few times. Usually, the zone would start working sooner or later, but sometimes that one would just be skipped. Thanks again.
