    I'm wondering if there is someone who can help me troubleshoot a particular Rainbird Controller I have for one of my customers:

    Rainbird Controller
    Model RC-7Bi

    Timer works, I can hear it ticking
    None of the zones work, all of them quit today
    There is power to the unit
    I manually go through all stations and none of them come on
    They all worked this morning while checking the zones
    I think it might be a burnt out Control Zone Selector Timer
    Or, could be the Station Dial Switch?

    Any help would be greatly appreciated.

    Thanks.

    Is the fuse blown? If it is, you probably have a short circuited solenoid.
     
  3. Is it moving from zone to zone on its own power with the switch in auto? If so I doubt the problem is the controller. That is a pretty reliable controller and the things you described are generally not what fails on that controller.

    Would somebody put this to music. Try singing the lines in a gregorian chant and it actually sounds pretty good.
     
  5. short circuited solenoid.

    Say this six times fast.

    The fuse is NOT blown

    Timer is ticking, and power is there

    All zones were working this morning, then they quit all together

    I noticed the (control zone selector timer) is VERY HOT

    Could this be a solenoid short, as one fella suggested?

    Solenoid shorts would blow the fuse. That assumes you have the correct fuse. Eliminate the field wiring (including solenoids) by resistance testing. Controller switching might fail, but it is very uncommon. And again, you use resistance testing to find the fault.

    Are you referring to the rapid advance motor? Don't you have a voltmeter to check timer output? Just cuz they worked this morning doesn't guarantee the problem lies with the clock. A few very basic troubleshooting skills would determine where the problem lies. Before you blow a bunch of money guessing at the problem you might want to bring in a pro.
     
  10. I think it is really rotten of those wascally valves to quit all together. You'd think they could take turns going out on different days.
