Are you looking for how to test a lawn mower starter with a multimeter? Then you are in the right place. If your lawn mower won’t start, it may be due to a faulty starter motor or a bad solenoid.

To determine the source of the problem, you’ll need to use a multimeter and test both components. A multimeter is an electrical testing device that measures voltage, current, and circuit resistance. It’s also essential for diagnosing problems with wiring and other electrical components on your lawn mower.

Steps For How To Test Lawn Mower Starter With Multimeter

By following these steps, you can use your multimeter to test the starter on your lawn mower with relative ease.

What is a Multimeter and How Does It Work 

A multimeter is a device used to measure electrical properties such as resistance, voltage, and current. It can also measure the continuity of electrical circuits or components.

Multimeters are essential for any mechanic working on lawnmowers or other small engine equipment. A multimeter can help diagnose issues with a starter motor quickly and accurately.

It can be used to test a variety of electronics, from home appliances to automobiles. It can also be used to test the starter on your lawn mower. A starter works with your lawn mower’s engine to turn it on when you press the starter button. To test a lawn mower starter, you must gather supplies and prepare your lawn mower for testing.

Gather the Supplies Needed

To use a multimeter to test a lawn mower starter, you will need the following supplies:

You will need a multimeter, an insulated screwdriver, electrical tape, and the owner’s manual for your specific model of lawn mower. Multimeters are available in a variety of shapes, sizes, and prices.

Choose one with the functions you need and ensure it is rated for your specific testing needs. Your owner’s manual will provide all the necessary information about your lawn mower.

Preparing the Lawn Mower for Testing

Before starting any electrical work, ensure the lawn mower is off and unplugged. Also, ensure that all the power sources, such as the battery, are disconnected. If you’re working on a riding mower, engage the parking brake before disconnecting the battery.

Read your owner’s manual to locate any important safety information or instructions. You should also take a few minutes to inspect the condition of all exposed wires and connections. If you notice any breaks in the insulation, fraying or other signs of wear, replace them with new parts before testing.

Locating the Starter Solenoid

Once the engine is turned off and all necessary supplies have been gathered, it’s time to locate the starter solenoid. The starter solenoid is a small electrical switch on or near the starter motor. 

It typically looks like a small cylinder with two wires attached to it. The starter solenoid consists of two posts, a positive and a negative. Refer to your owner’s manual for the exact location of the solenoid on your specific lawn mower model. 

Connecting the Multimeter to the Starter Solenoid

Next, you must set up your multimeter according to the manufacturer’s instructions. Make sure your multimeter is set up correctly and that it is rated for your specific testing needs. 

Carefully remove one of the wires from the starter solenoid and attach it to one of the multimeter’s terminals. Then attach the other wire from the starter solenoid to the other multimeter terminal. Now you’re ready to begin testing.

Interpreting the Results of Your Test

You can test for continuity between the two posts on the starter solenoid by setting it to continuity mode. If there is a continuous connection between the two posts, then this indicates that the starter motor is functioning properly. However, if there is no continuity between the two posts, this indicates a problem with the starter motor. 

With the multimeter connected, turn on your lawn mower and press the starter button. The multimeter should read “12V” or higher when you press the starter button and then drops back down to 0V once you release it. If the multimeter does not read 12V or higher, it may indicate a problem with the starter solenoid.

Troubleshooting Common Lawn Mower Start Problems

If you find that the starter motor is not functioning properly, it’s important to troubleshoot the issue before replacing any parts. You may need to clean or replace the spark plug, replace the battery, or check the fuel lines for clogs and leaks. 

The most common cause of electric starter failure is a loose or damaged connection on one of the starter solenoid posts. To check for these issues, use a Phillips head screwdriver to remove the post and inspect it for damage or corrosion. 

If there is any visible damage or corrosion, you can clean the connections using small pliers or wire cutters. If you cannot diagnose the problem yourself, take your lawn mower to a qualified repair shop for further inspection.

Remember always to follow the safety instructions in your owner’s manual, and if you are unsure about any part of the process, consult a qualified professional for help.
