Sprinkler zone starts, but then quits
All,
I'm new to the site so first let me start off by saying hello. I'm a homeowner newbie that is in the military. I do have experience in electrical systems though. So, I have noticed when I wake up in the morning that my grass and driveway isn't wet as it should be since my irrigations system starts at 6am. I ran the system in manuel starting with zone 1. It began to run for about 1 minute and quit working. Tried to go to zone 2 and then zone 3 with no luck. I tried to restart zone 1 and it wouldn't kick on. The next day it did the same thing. So, let me tell you what I have done so far.
1) Manual turned the valves, all zones work properly. I know it isn't a pressure issue.
2) Figured it was an old controller,so bought a new one...still didn't work.
3) Got a volt meter and checked the readings when zone should be activated. All zones where 28VAC...I realized I can return the new controller.
4) disconnect all wiring. Read OL on each wire reading individual. Shorted wires and read a short. I know the wiring is good, and has good conductivity.
5) I read each solenoids resistance. Zone 1 and Zone 2 (Hunter ASV-101) read 24 ohms. Zone 3 (orbit 57623) read 30 ohms. I figure the difference is because it is different brands.
I checked connections but not thoroughly at the time. I figured if system came on for a minute, then connections had to be good. Any help on this system would be greatly appreciated. Dtirey
