How do I test my irrigation system with a multimeter?
Here are some simple steps to test your irrigation system with a multimeter: 1. Open the controller box. Make sure that all wires are connected and make certain that there is a battery for backup power. If any wires are loose, use a small Philips head screwdriver to reattach them to the controller. Test all stations and see if they turn on.
How do you test a central turf and irrigation supply?

Turn the watering zone that is malfunctioning on manually at the controller. Touch one multimeter lead tip to the common wire on the controller, which is usually white.
How do you troubleshoot a broken irrigation control?
The normal reading is 24 V. If the voltage is below 22 V, the irrigation control is malfunctioning. Turn the multimeter dial to the "Ohms" setting, says Sprinkler Warehouse. Turn the irrigation controller off manually. Turn the screw on the defective zone in the controller counterclockwise with a flat-head screwdriver to loosen it. Remove the wire.
How do you test a sprinkler system?
The controller typically has a "test" button or something similar. Each cycle will be brief, perhaps up to 5 minutes each. It probably is a 2 person job to test. One to push the test button, another to "follow" the activity and record which section is irrigated by #1, #2, #3, etc. Cell phones should help the 2 persons stay in touch.

How many ohms should a irrigation solenoid have?
between 20 - 60 ohmsFor irrigation applications, a solenoid is considered to be good if its resistance is between 20 - 60 ohms. It is best to compare resistance measurements to that of a new solenoid. Example, if a solenoid measures 44 ohms, it would be considered good because it is between 20 - 60 ohms.
How many ohms should a solenoid read?
If you have 0 ohms, it means the coil is shorted. While the infinity read indicates the coil is open, the wire is broken inside.

What voltage are irrigation solenoids?
Irrigation systems utilize a 24VAC electronic signal to initialize a valve's solenoid. Even though the system is low voltage, it is still always recommended a trained professional perform these tests.
Are irrigation systems AC or DC?
ACAC volts (VAC) – Alternating Current, this is household voltage. Most irrigation solenoids operate on AC voltage. DC volts (VDC) – Direct Current, the normal source is a battery.

What is an irrigation system controller?
Irrigation systems include a controller with electrical wires leading to each valve that controls a watering zone. When a watering zone will not activate, you can use a multimeter to test all of the components for troubleshooting.
How to read a water solenoid?
Rotate the multimeter dial to "Ohms" and place one lead to each of the two wires on the solenoid. The solenoid is a black, round object on top of the valve that opens and closes the water flow. The reading should be the same as it was at the irrigation controller; if not, the solenoid is defective and needs replacing.
