Rainbird sprinkler system not working
I am having a difficult time fixing my sprinkler system. I have a rainbows system. All of the vavles are in separate places inline with the corresponding zones. I have tested the control box and it is good. All of my silindoids are good reading an impedance of 40.00 on the multimeter. The only zone that will run is zone #3. Even a manual attempt will not turn them on. Another issue. I opened all of the zones from the silinoids except for the one coming from the main water source. Which is zone 3.. And then run zone 3 and all of the sprinklers come on at once. With all of the valves closed the only one that will run is zone 3... Btw, zone 3 runs just fine on the timer, like it's suppose to!!! Help!!!
