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

While running a manual cycle, my sprinkler system suddenly turned off and I can not get it to come back on. It is a Weathermatic LawnMate sprinkler system that I have been using the manual controls with no problem until now. I read the Troubleshooting part of the manual and changed the backup 9V battery (which was corroded), and also put a new fuse in. The display shows each cycle to work, but nothing is happening in the yard. Water company says everything is fine, too. I've located the two valve compartments in the yard, but do not know what to look for to check things there. Help??? Another thing, the day before the system quit working, we de-clogged a few nozzle heads, allowing those nozzles to work when they had not been working. After this, the system ran with no problem several times, until the next morning when it quit during Cycle 1.

Yes, it is running on city water. Forgive me, but I'm extremely uneducated in this area. If it is a problem with the valves or the wiring, does that mean in the ground box from the city, or one of the two ground boxes that came with the sprinkler system? Either way,what would I do to check valves and wiring myself? I'm very much trying to not have to call a professional.

I can confirm that the fuse is being blown out immediately when I press "start". I can see it flash. So what would be my next step in determining the problem causing it?
