The Battery Doesn’t Have Enough Charge

You can tell this is the problem if a battery-powered mower starts experiencing issues right after you start it or if it only runs for a short time before dying.

These mowers come with a feature that shuts off the device when the battery gets too low to prevent damage to the battery. So, if your mower keeps dying, it’s likely because the battery needs to be recharged.

How To Fix

A low battery is an easy fix. You just need to recharge it. Depending on the charger you have, it will either have an indicator light that turns green when the battery is fully charged or it will automatically shut off when the battery is full.

I keep extra batteries charged and ready so that I can keep mowing while the depleted one recharges.

If you find that your battery is dying frequently, even after recharging it, it’s best to replace it. As batteries age, they start losing their ability to hold a charge. Check the user’s manual for compatible replacement batteries.

The Electrical System Is Faulty

The most common issues include a faulty on/off switch, cuts or frayed wires, a damaged power cord, or a loose connection.

Faulty On/Off Switch

On/off switches can become faulty after prolonged use or if there is dirt or debris build-up, causing it to stick in the on or off position. Using a multimeter to check for continuity, you can test if the on/off switch is working. If there is no continuity, the switch needs to be replaced.

Cuts or Frayed Wires

One of the most common electrical problems is cuts or frayed wires. The wires in your lawn mower can become damaged from exposure to the elements, wear and tear, or rodents. When the insulation on the wires is damaged, it can expose the bare wire, which can cause shorts and electrical issues.

Additionally, it affects the current flow and can cause the mower to die. You can check whether the wires have sustained any damage by looking for missing insulation, frays, or cuts.

Unplug the mower from the power source before inspecting the wires. If you find any damaged wires, cut out the damaged section of the wire and use wire connectors to splice in a new piece of wire.

Damaged Power Cord

For cord-powered mowers, here’s one to be mindful of.

When the cable is damaged, it inhibits the flow of electricity and can cause the mower to die. The main type of damage the cord can sustain is a cut. This can happen from running it over with the mower or exposure to the elements.

A Loose Connection

Your mower’s electrical system relies on tight connections to function correctly. Any loose connections can cause an interruption in the flow of electricity, leading to the mower dying. The most common loose connection is a battery terminal that’s not tightly connected to the battery.

Tripped breakers and blown fuses are also a cause. These happen when too much current flows through the circuit, causing the breaker or fuse to trip and shut off the flow of electricity.

Most of the time when a lawn mower won’t start the cause is a problem with the gas or the lawn mower carburetor.

What to Do if Your Lawn Mower Won’t Start

Whatever kind of lawn mower you’ve got, the last thing you want once winter finally lifts and spring has sprung is a lawn mower that won’t start.

If you’ve taken the proper steps to winterize your lawn mower, you’re far less likely to be dealing with such issues. It’s also why you should tune up your lawn mower at the start of every season. However, it’s not out of the ordinary to find your gas-powered lawn mower not starting from time to time, so it’s important to know why your lawn mower isn’t starting and how to fix it.

Project step-by-step (6)

Check the Gas Tank

Let’s start with the obvious. Before you have a heart attack pulling on the rip cord, you’ll want to check the fuel. Like any gasoline-powered engine, lawn mowers run out from time to time. Maybe you forgot it was running on fumes when you finished mowing last time. It sounds simple, but we’ve all overlooked the gas tank from time to time.

Even if there is gas in the mower, if the fuel’s been in there more than a month, that could be the problem. Gas sitting around too long in the tank can get contaminated with dirt and extra moisture.

So if your gasoline has been in the mower for more than month, drain the gas properly, dispose of it correctly, and fill up the mower with new gas. It may take quite a few pulls to suck the new gas into the lawn mower carburetor, so be prepared to clean and dry the plug a few more times.

Add fuel stabilizer when you fill up the tank to help protect the gasoline in there from dirt and moisture.

Family Handyman

Check the Spark Plug

Start by making sure the lawn mower spark plug cable is connected to the plug itself. It’s quite possible that it got pulled off there over the winter while the mower was being stored in the garage.

If that’s not the issue, the next step is to remove the spark plug to see if it’s wet. There’s no way the engine will start if it is. So clean the plug with carburetor cleaner and let it dry. Cleaning it with compressed air isn’t enough; you need a solvent to remove oil residue. If it’s really grimy and dirty, it might be best to change the spark plug.

Check for Debris in the Mower Deck

Grass clippings can get clogged in the mower deck, which can prevent the blade from turning. This is a common problem if you’ve cut wet grass or let the lawn get especially long and bushy between cuttings. If the cord is hard to pull, that’s a good sign that there’s debris clogging up your mower’s deck.

This is a pretty easy problem to solve. With the mower off, flip it on its side or upside down and scrape out the gummed up grass clippings. Once that’s done, you can flip it back over and start it up again.

Check the Air Filter

The lawn mower’s carburetor regulates the mix of gasoline and air going into the engine where it’s burned to create power. Before air goes into the carburetor it passes through the air filter which prevents dirt and debris from getting into it.

If the air filer is clogged or dirty, it throws the ratio out of whack. Sometimes that results in your lawn mower smoking, and sometimes it prevents it from starting entirely. So take a look at the air filter to see if it’s dirty. If so, you can clean it or just change it outright.

Check the Carburetor

Another common reason for a lawn mower that won’t start is a clogged or dirty carburetor. It can also cause your mower to run rough or spew black smoke when you’re trying to cut the grass. If that’s the case, you may need to clean the carburetor.

To get to the carburetor, you’ll have to remove the air filter. Once that’s out of the way, you can remove the carburetor in order to clean it.

Once it’s out, check for corrosion. If you see chalky/powdery white corrosion like this, it’s probably better just to replace it. To clean it, take it apart and spray carburetor cleaner on the parts and inside the housing. After that, put the carburetor back together and reinstall it in the mower.

Check the Fuel Filter

Like the air filter, the fuel filter prevents dirt and debris from getting into the combustion chamber of your lawn mower’s engine, taking that stuff out before the gas gets mixed with air in the carburetor. Problems with the fuel filter might also result in the engine sputtering or rough idling, even before it gets to the point of preventing the mower from starting.

To start, tap the side of the carburetor to help the flow of gas. If that doesn’t work, you might have a clogged filter.

Not all lawn mowers have a fuel filter, but for the ones that do, it’s usually located in the fuel line or the fuel tank. To find out where the fuel filter is at, check your lawn mower’s owners manual, which will also tell you what type of filter it is.

If the filter is in the fuel tank, you’ll need to drain the gas from the mower into a drain pan, assuming you can’t run the engine until it’s out of gas. If the filter is in the fuel line, clamp off the fuel line before removing the filter. Once you have the filter off, you can check to see if it’s dirty and clogged by holding it up the light. If it is, install a new one. Make sure it works with this lawn mower maintenance checklist.

How Does a Lawn Mower Starter Work?

The starter for a lawn mower is responsible for starting the engine. It does this by turning over the flywheel and sending an electrical current through to the spark plugs, which then ignite the gasoline in order to turn on the engine. In order to do this, the starter has a coil that creates an electromagnetic field when it’s energized. This magnetic field interacts with the armature of the flywheel and causes it to spin, thus starting the engine. The starter is powered by a battery connected to it through two wires, positive and negative. When you press down on the start button or pull on its cord, current flows from one wire into the other, creating a circuit and activating the starter. [1]

Safety Tips

When troubleshooting the lawn mower starter with a multimeter, safety should be your number one priority.

Make sure you are wearing gloves and safety goggles to protect your eyes and hands from any possible sparks that may occur during testing.

Additionally, make sure you shut off the power source (battery or wall outlet) before making any connections with the multimeter. When working on the lawn mower’s engine, be aware of any loose wires or components that could come in contact with hot metal parts of the engine.

Lastly, always unplugging the spark plug when testing electrical parts so as not to create an electric shock hazard. Following these safety tips can help make sure that your work remains safe and effective.

After confirming that safety measures are in place, testing the lawn mower starter using a multimeter is straightforward. [2]


Tools required for testing a lawn mower starter with a multimeter include the multimeter itself, an adjustable wrench or pliers, and insulated wire cutters. Before beginning, make sure to disconnect the spark plug and switch off the ignition system of the lawnmower.

Testing the Lawn Mower Starter

Testing the lawn starter with a multimeter is an easy and straightforward process. First, you’ll need to locate the lawn mower’s starter motor. It should be near the bottom of the engine and look like a small metal cylinder with two wires coming out of it.

Once you’ve located the starter motor, attach one of the multimeter probes to each wire. Set your multimeter to a low voltage setting, such as 2 volts or less. If there is power running through the starter motor, then your multimeter will indicate that there is a current flowing through it by showing some kind of reading on its display.

If your multimeter has no readings at all, this could mean two things: either the starter motor isn’t receiving any power or it is malfunctioning and needs to be changed. If this is the case, it’s best to take your lawn mower to a qualified mechanic who can diagnose and repair the issue.

You have now successfully tested your lawn mower starter with a multimeter! By following these simple steps, you can detect any issues that may be causing problems and take the necessary actions to keep your lawn mower running smoothly. [5]

Causes of Starter Failure

There are several common causes of starter failure in a lawn mower.

One of the most common is lack of lubrication, which can cause problems such as sticking and grinding gears, or a seized motor. The brushes may also wear out due to high use, and may need to be replaced if they do not work effectively in providing power to the motor.

Corrosion on the parts can also reduce electrical conductivity and prevent them from working correctly.

Testing with a multimeter is an effective way to identify these kinds of issues before replacing any parts.

It’s important to make sure that all wires and connections are secure so that electricity is able to flow freely throughout the system.

Replacing worn-out spark plugs or faulty wiring can also help improve the starter’s performance.

It can be helpful to refer to the manual for your lawn mower to determine which parts need to be tested, as well as what type of multimeter should be used. By using a multimeter and following the steps outlined in the manual, you can accurately identify and diagnose any issues with your lawn mower’s starter. This way, you can make sure that your machine is running efficiently and safely all season long!

Types of Multimeters

There are several different types of multimeters, each designed for a specific purpose. An analog multimeter uses a needle to display the voltage or current being measured. Digital multimeters use an LCD screen that displays numerical values such as AC/DC voltage, current, resistance, etc. Some digital multimeters also come with additional features such as temperature probes and frequency counters. When testing a lawn mower starter with a multimeter, it’s best to use either an analog or digital type since these are able to send accurate readings faster than other models.

When using a multimeter to test a lawn mower starter, you will need to have some safety equipment on hand including safety glasses, gloves and insulated tools. Also make sure to disconnect all power sources before attempting to test any electrical systems.

Testing A Starter Solenoid Could Be Dangerous

With all of the complexity associated with lawn mowers, it is important to remember that testing a starter solenoid could be dangerous. This is because of the power and voltage involved in operating a starter solenoid. If you do not know how to use a multimeter correctly, or are unsure about your safety when working around electricity, please consult an experienced professional before attempting repairs on your own.

It is also important to wear protective gear such as goggles and gloves during any electrical repair work. Doing so will keep you safe from electric shocks or sparks while handling exposed wires and other components.

Once you have gathered the necessary materials and taken the appropriate precautions, you are now ready to begin testing your lawn mower’s starter solenoid using a multimeter.

Benefits of Testing a Lawn Mower Starter with a Multimeter

Firstly, it provides a more accurate test result than other methods such as visual inspection or manual testing. This helps you determine the cause of any issues quickly and accurately.

Secondly, it’s easy to use, requiring few tools and little to no experience.

Lastly, it can save time and money by avoiding unnecessary repairs or replacements due to faulty parts. Testing a lawn mower starter with a multimeter is an excellent way to keep your machine running smoothly for years to come. [6]


How do you test a lawn mower starter with a multimeter?

To test a lawn mower starter with a multimeter, you will need to set your multimeter to the Ohms setting. Disconnect the cables from the starter solenoid and connect one lead of the multimeter to each terminal on the solenoid. The resistance should be close to zero ohms if the starter is working properly. If not, then there may be an issue with either the wiring or the starter itself that needs to be addressed.

What can cause my lawn mower’s starter motor not to work?

The most common cause for a lawn mower’s starter motor not working is a lack of power from its battery. Check that all connections are securely attached and that it has enough charge. Other possible causes include worn out brushes in the starter motor, corroded or broken cables, a faulty solenoid, or a faulty ignition switch. If all of these components have been checked and are working properly, then the problem may lie within the flywheel.

What should I do if my lawn mower’s starter won’t turn?

If your lawn mower’s starter won’t turn, first check that it has enough power from its battery. Also inspect the wiring and connections for any damage or corrosion. If everything appears to be in order, you may need to replace either the starter motor or the flywheel. It is also important to check for any obstructions that may be preventing the engine from turning over.

What is the difference between a starter motor and a starter solenoid?

A starter motor is responsible for turning over an engine to initiate combustion. A starter solenoid, on the other hand, is an electrical switch that sends power to the starter motor when it receives a signal from the ignition switch. The solenoid provides additional protection by preventing direct current from flowing through the battery cables when the engine is not running.

How do I know if the starter on my lawn mower is bad?

Using a multimeter, you can test the starter on your lawn mower to determine if it is in working order. To test the starter, first make sure that all power sources are turned off and disconnected from the lawn mower before testing. Once you have done this, connect the two leads of the multimeter to either side of the battery terminals on your mower and set the meter to “DC voltage”. If your reading is above 12 volts then your battery is charged and working properly.

Can you bypass a starter?

Yes, you can bypass the starter on a lawn mower. To do this, you will need to connect the two battery terminals and the solenoid terminal together with a jumper wire or an alligator clip. Once this is done, your mower should start without having to use the starter. However, it is important to note that bypassing the starter may damage other components of your mower if not done properly. Therefore, it is strongly recommended that you consult a professional before attempting to bypass the starter on your lawn mower.

Can I test my lawn mower’s spark plug with a multimeter?

Yes, you can use a multimeter to test your lawn mower’s spark plug for functionality. First, disconnect the spark plug from the engine. Then, set your multimeter to measure resistance (ohms). Connect one of the meter’s test leads to each end of the spark plug and check for a reading between 5K ohms and 10K ohms. If you get any other reading, replace the spark plug as it is faulty. Make sure to install a new spark plug with correct gap distance according to your manual instructions before reconnecting it. Proper installation is important in order for your lawn mower starter to work properly. You should also inspect all wire connections connected to the ignition system such as those leading to and from the ignition switch, coil or magneto, which can cause starting problems if worn or frayed. Additionally, inspect the spark plug wires for any signs of corrosion or damage and replace them if necessary. Once you have ensured all connections are in good working order, complete an ignition system test using your multimeter. Set the meter to measure resistance (ohms) and connect one test lead to each end of the spark plug wire (or magneto) while it is disconnected from its other connection. If there is any resistance other than 0 ohms, then you know that something is wrong and should inspect the wiring further or replace it altogether.

Why is my starter not clicking?

If you are experiencing an issue with your lawn mower’s starter not clicking when the key is turned, it could be a sign of a faulty connection or bad wiring. Testing the starter with a multimeter can help to determine if there is an electrical problem. A multimeter is an electronic device used for testing and measuring electric current and voltage in a circuit. Before testing the starter, make sure that all safety precautions are followed including unplugging the power cord from its source and removing any spark plugs or fuel lines connected to the engine.


Testing the starter on a lawn mower using a multimeter is easy. After unplugging the spark plug, connecting the test leads to their respective terminals and setting the multimeter to measure resistance, you can get an accurate reading of the starter’s electrical circuit. To ensure that your measurements are accurate, always double-check your readings with other testers such as ohmmeters or continuity testers. If there is any discrepancy in results, contact a professional mechanic for further troubleshooting and repair. Taking these steps will help make sure that your lawn mower’s starter is running correctly so you can enjoy another wonderful season of cutting grass!


Riding Lawn Mower Won’t Start, No Clicking — Solutions When Your Riding Mower Does Nothing When You Turn The Key

If you buy something through our posts, we may get a small commission. Read more here.

Dealing with a non-starting riding mower can be incredibly frustrating. However, if you’re experiencing a situation where the engine doesn’t make any clicking sounds, there may still be hope for a simple fix without having to replace the mower just yet.

Below, our experts have put together the potential issues with a riding mower that won’t start or click and provide troubleshooting tips to help your riding mower work again.

How to Fix a Riding Lawn Mower That Won’t Start

“Should I call a professional when the riding mower does nothing when I turn the key?” The answer is: not always. You should be able to find out the problem with your tractor or mower yourself. But first, ensure you set the parking brakes.

Then check if the blade is still disengaged. Your riding mower won’t work otherwise.

Materials You Will Need

  • Work gloves
  • Safety goggles
  • Multi-meter
  • Screwdriver
  • Wire brush

How a Riding Lawn Mower is Powered

Riding mower is powered by a four-cycle engine (intake, compression, combustion, and exhaust). Some mowers use gasoline as their fuel and a spark plug to combust it. Others are powered by diesel and require no spark plug. In either case, the engine runs the transmission and drive wheels, and rotates the cutting blades underneath the machine.

Like automobile car, riding mower requires to charge a battery, starter motor, and ignition switch. When you turn the ignition switch to the ‘Start’ position, 12 volt of direct current travels from the battery through the starter solenoid to the starter motor. This current also flows through a cable to the anti-afterfire solenoid in the engine

When you release the key to the ‘Run’ position, this DC of twelve (12) volts is then redirected. Instead of going to the starter and motor, it moves to the alternator and anti-afterfire solenoid only. Together, these parts help to charge the battery and start auxiliary power sources like headlights and power plugs.

If your high-quality zero turn mowers work fine, you would hear a clicking sound between the ‘Run’ and ‘Start’ positions. This implies that the starter solenoid is getting power from the battery. On the other hand, when you don’t hear a click from the engine, the starter has failed, or its coil isn’t getting power from the battery.

Although mowers differ from models, they all work on the same principles.

Check and Charge/Replace Dead Battery

Battery troubles are one of the most common reasons a mower won’t run or click. A corroded battery won’t start an engine, and neither will a drained battery, when you forget to turn off the safety switch. Corrosion can be a usual problem for used riding lawn mower models at cheap of 500 below, so make sure to check this when you buy one.

A service monitor on a mower can help you identify when you’ve got battery troubles. But without one, you can check the battery using a multi-meter by following these steps:

  • Turn off the ignition system before accessing the battery.
  • Set the multimeter to DC voltage
  • Use the multi-meter’s red probe to touch the positive terminal and the black probe on the negative terminal.

If the multitester reads more than twelve (12) volts, the battery is good. Otherwise, it is weak, or dead and you’ve found the problem with your mower.

  • Accessing the battery, which is usually under the driver’s seat.
  • Connecting the charger clips to the battery terminals.
  • Plugging the charger to a power outlet. The charger should work on at least 10volts to charge the battery. Still, a 12-volt charger is sometimes preferred.
  • Disconnecting the charger reversing the steps above.
  • Plugging the charger to a power outlet. The charger should work on at least 10volts to charge the battery. Still, a 12-volt charger is sometimes preferred.
  • Replacing the seat and reconnecting the new battery in your mower correctly.

If a simple recharge doesn’t work, you need to replace the battery pack in the mower. Avoid a jump start mower to prevent damages to the on-board system

Check the Ignition Switch

The problem with your mower could be with the switches. When you start the engine and your riding mower does not forward nor reverse, your ignition switch’s contacts complete a circuit. This circuit is from a red to a white wire, which is on the B-terminal and S-terminal, respectively.

  • Pull up the mower’s hood to access the ignition switch.
  • Remove its cable harness.
  • Remove the tabs to pull the ignition switch out of its slot.
  • Turn the key to the start position and set the multi-meter to measure resistance, not voltage.
  • Connect the black multi-meter probe to the B prong and the other to the S prong. These terminals are along each other’s diagonal at the bottom of the switch.
  • Use the key to turn the ignition switch and start the engine. The resistance should display on the multi-meter when you do this.

The top-rated riding mowers should have good ignition switch measuring 0 ohms. This means its contacts complete the B and S terminal circuit and can send voltage to the solenoid. On the other hand, a damaged ignition switch will measure infinite resistance.

Other common issues you can experience with a damaged ignition switch include loose wiring and connections, corrosion, or spinning ignition. To fix this problem, check the ignition wiring for corroded, damaged, or loose wires

Inspect the Control Module

A control module is a printed circuit with resistors, relays, and a ground side that receive commands from the safety switches. If the sensors in the motor work correctly, a circuit module will also output a command to the starter through the solenoid. However, not every mower has one.

Depending on your model, a control module could be anywhere, even under the seat. And if you notice that your high-quality electric riding mower won’t start and no clicking comes from the device, or cranking doesn’t work, then this module could be faulty.

There are two ways to check the control module yourself:

  • Wiggle test: Here, wiggle the red and black wires connected to the control module while you start the mower. If everything checks out fine and the wires are connected, visually check the printed circuit for water damage and loose connections. To save time, you may have someone help you with the wires in a wiggle test while you FOCUS on finding the issue.
  • Main fuse check: Modules have internal or external fuses, and a blown fuse cuts out the supply from the battery. First, to check the fuse, remove its zip tie and then pull the fuse from its holder. If any element in the fuse is broken or there’s a fault in the ground connection, you should have it replaced. However, if you’re unsure, you can check for continuity using your multi-meter.

A good fuse should measure near 0 ohms. On the other hand, a blown fuse will measure infinite resistance.

Check Safety Functions

Every mower even the cheapest riding mower you can find in the market has in-built safety features. Typically, sensors or switches control these features, and they are routed through the control module. Once a detector activates a safety function, your mower won’t work as usual.

The main ones to check are the brake pedal switch, blade switch, battery connection, weight sensor (to make sure a driver is sitting before the mower works).

When you jump start the engine, you should press your brake pedal. If the brake pedal doesn’t work, then you need to inspect your brake detector.

  • Remove the hood and air-duct screws.
  • Pull off the air duct and take the fuel tank and filter out of the way.
  • Pull the cable harness off the brake switch, noting the wiring.
  • Using the multi-meter probes, touch both prongs that connect to the wiring of the brake detector.

If the brake switch is okay, the multi-meter should display 0 ohms of resistance. Replace this switch if you read infinite resistance from your multi-meter.

A riding mowers engages when the blade knob is switched off or the transmission isn’t set to park. To check the blade switch, our experts recommend to do the following:

  • Take out the clutch lever mounting screws. The assembly should drop slightly when the screws aren’t in place.
  • Note the prong’s wiring and then disconnect the blade switch’s cable harness.
  • Using your multi-meter probes, touch both prongs to measure the resistance of the blade switch.
lawn, tractor, electrical, troubleshooting, electric, mower

Like before, 0 ohms implies your blade switch is good, while infinite resistance means you need to replace it.

Motion detectors, switches, and sensors have in-built override functions. These functions are generally used for tests, and simply disconnecting a detector can cause an override. If you suspect your sensors are on an override, our team suggests to reconnect them before starting the device.

Replace Faulty Solenoid

Follow these steps to change a faulty solenoid:

  • First, raise the seat to get to the battery. Then, disconnect the battery terminals, starting with the negative (colored black) and then the red
  • Remove the battery from its slot. While at it, check for leaks or corrosion at the bottom and sides. Clean corrosion off the cable leads with a wire brush if they are still there after dusting.
  • Disconnect the cable harness that’s connected to the seat’s detector.
  • Pull off the battery box after removing its clips or screws.
  • Note the wiring connected to the solenoid and then disconnect the cables in any order.
  • Remove the mounting and tab both with a screwdriver.
  • Remove the faulty solenoid and replace it with the new one.
  • Finally, replace the seat, battery, and other parts.

While you can repair some solenoids, it’s often better to change them for longevity. In this way, you can still have the opportunity to place your riding lawn mower on retail in the long run given that the equipment is properly maintained.
