Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
sprinkler help please
I have a hunter XC system. 8 zones. 1 zone (3) will not turn on unless I do so manually by turning the solenoid to on, then the heads pop up and it waters like normal.
Today I swapped solenoids from zone 1 and 3 thinking it was a solenoid. Nope. Zone 1 still worked with the zone 3 solenoid but nothing for zone 3 still.
Valve?
Electrical?
What say the experts?
Probably the activation relay for the solenoid.Originally Posted by sniper7
Are you using all eight zones? If not just switch the wires over to another zone and see it that works.
Check for voltage at the valve. If you don't have a meter disconnect wires from a zone that does work and try to turn it on at the controller.
Check the connection of the wire at the clock.
Make sure there is time on zone 3 at the clock.
See if another zone will fire up when you touch that wire at the clock to another zone at the clock.
Swapped wires for zone 2 (yellow wire) and zone 3 (brown wire). Brown wire was the problem at zone 3 and when on zone 2 it won't run zone 2. So it seems I have a wiring issue.
How might I got about fixing that?
electrical
check continuity at the clock. (#3 to common)
turn the station on and check for voltage at the clock (24V #3 to common) then check for voltage at the valve
if you have voltage at the valve, it's that solenoid (not likely if you did what you say you did) on that valve
if you have voltage at the clock and not at the valve, you have a break in the wiring somewhere and you probably got no continuity.
if you have no voltage at the clock, it's the clock
residential installs always use the cheapest shit possible, and shitty multi-strand wiring doesn't survive being the ground for long, it always goes to shit, along with crappy non underground rated connections.
solenoids used to rarely fail, but when they all went to made in china crap they just die and short out at about the 10 year mark. Luckily it's an easy fix.

Do you have any spare wires? If not you are going to have to run a new wire or run two zones at once if you have enough water pressure.
