Are you wondering how to test a solenoid with a multimeter? Don’t worry, we’re here to help. In this blog post, we’ll show you how to do just that. So whether you’re a beginner or an experienced solenoid tester, this guide will be helpful.

1. Introduction

A solenoid is a coil of wire that creates a magnetic field when an electric current flows through it. Solenoids are used in a variety of applications, including door locks, car starters and electric motors. If you need to test a solenoid for continuity, you can do so with a multimeter.

What is a Solenoid?

A solenoid is an electrically operated device that can be used to open or close a valve. Solenoids are often used in automotive applications, but they can be found in a wide variety of devices, from doorbells to washing machines.

When a current is passed through the coil of a solenoid, it creates a magnetic field. This magnetic field can then be used to either open or close a valve. The strength of the magnetic field depends on the strength of the current passing through the coil.

Solenoids are classified according to the number of turns in their coils. The most common type of solenoid has a single turn. However, there are also solenoids with two, three, or even four turns. The more turns there are in the coil, the stronger the magnetic field will be.

What is a Multimeter?

A multimeter is an electronic measuring instrument that combines several measurement functions into one unit. These functions include the ability to measure voltage, current, and resistance. Multimeters can also be used to test continuity and to measure capacitance.

How to Test a Solenoid with a Multimeter

A solenoid is an electro-magnetic coil that, when powered, creates a magnetic field. This field can then be used to interact with ferrous (iron-containing) objects. Solenoids are found in a wide range of applications, from door locks to electric valves.

If you need to test a solenoid, you can do so with a multimeter. With this testing method, you will be able to determine if the solenoid is grounded, if there is continuity through the coil, and if the coil is open or shorted.

To test a solenoid with a multimeter:

1. Set your multimeter to the “resistance” setting.
2. Place the red multimeter lead on one of the large terminals of the solenoid.
3. Place the black multimeter lead on the other large terminal of the solenoid.
4. If the reading on the multimeter is zero ohms, then the solenoid is grounded and functioning properly. If there is no continuity, then the coil is open or shorted and will need to be replaced.

Testing the Solenoid Coil

To test the solenoid coil, you will need a multimeter. You can purchase one at most hardware stores.

1. Set the multimeter to the ohms setting.
2. Place the probes on the two terminals of the coil.
3. If the reading is zero, then the coil is functioning properly. If the reading is infinity, then the coil is broken and will need to be replaced.

Testing the Solenoid Valve

A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in simple terms, a coil of wire. When the current is turned on, it creates a magnetic field which moves the plunger and opens the valve.

You can easily test a solenoid valve with a multimeter. First, turn off the power to the device. Next, remove the covers of the device to expose the wires leading to the solenoid. Using your multimeter, set it to Ohms and touch one lead to each of the two wires. If there is continuity, the meter will beep or register a number other than infinity (OL). If there is no continuity, you will need to replace the solenoid valve.


Once you have your multimeter and know how to set it to the ohm setting, testing a solenoid is a relatively simple matter. Touch one probe to each of the large terminals on the solenoid. If you get a reading of infinite resistance, then the solenoid is not working and should be replaced. If you get a low reading (depending on the type of multimeter you’re using, this could be anywhere from less than 1 ohm to several thousand ohms), then the solenoid is working and you can move on to testing other components.
