Rain Bird system not working!
i have Rain-bird system that came with my house, the system was placed back in 2002 when the property way developed. i have a Rain bird ISM Series system in garage.
i have 4 zones, few days ago i notice that after the timer goes through all 4 zones it starts again at zone 1 and keeps repeating. i have timer set to 11:30pm on ALL 4 ZONES. first they still don't come-one at same times, even though i set it up that way. now this is the first time i set all 4 zones to come-on at same time. second they keep restating 1-4 again, and again.
i just unplugged it today, i had no battery in it, so i powered the controller off from the wall. any suggestions what i need to do.
