The quickest way to test the solenoid valve is to apply a charge directly to it. There are two wires which cross directly above the valve as it lays in the timer that you will touch with a multimeter. This should send a charge onto the valve, and if it is functioning normally, it will open.
– Open your irrigation controller box. …
– Turn on a multimeter and turn the center dial with the arrow pointing to the voltage setting. …
– Turn the multimeter dial to the “Ohms” setting.

How can you tell if its the battery or the starter?
Your car starter has a really important job to perform – frequently. The battery sends a burst of energy to the start which uses this energy to turn the engine over and get it car started. If you put the key in the ignition, but only hear a click when you turn the key, you’ve got a problem with your starter.

How do you test a starter solenoid with a multimeter?
What happens if a sprinkler solenoid goes bad?
Your sprinkler controller sends an electric current to the solenoid in order to activate it and open the valve and cuts off the current to the solenoid to close the valve. If your solenoid is bad, the water pressure in the sprinkler chamber will not be changed and the valve will fail to open.
What are the symptoms of a bad starter relay?
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won’t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
How do you test a sprinkler solenoid with a multimeter?
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.
How many volts should a starter solenoid have?
8 volts
How long do sprinkler solenoids last?
12-15 years
How many ohms should a solenoid have?
For 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 do I know if my starter relay fuse is blown?
Symptoms of a failing starter relay include problems starting the vehicle, the starter staying on after the engine is cranked, and a clicking noise coming from the starter.
Why do sprinkler solenoids fail?
When a solenoid valve (also called an electric valve or automatic sprinkler valve) fails to close it is almost always because something is stuck inside it. This might be a grain of sand, a small twig, a insect, or even a tiny snail. To fix the valve you need to disassemble and clean it.
What is the voltage of a sprinkler valve?
Electric solenoid valves are powered by 24 volts AC (VAC) from the irrigation controller.
How do you troubleshoot a solenoid?
– Solenoid valve doesn’t open / close properly. Check power supply and make sure voltage and frequency are correct. …
– Coil burned out, melted or cold with power on. …
– Solenoid valve leaks.
