Safety First

Before checking your lawn mower starter, it’s essential to prioritize safety. Electrical components can be dangerous if not handled properly.

Firstly, ensure that the mower is turned off and the spark plug wire has been disconnected. This will prevent the engine from potentially starting while you’re working on the starter.

It’s also recommended to wear insulated gloves to prevent any electrical shock.

If the starter needs to be removed for testing, be sure to follow the proper safety protocol when handling the starter. Avoid touching any exposed wires or components, and keep the starter away from any flammable materials to prevent fire hazards.

Remember that it’s always better to be safe than sorry. By prioritizing safety, you can avoid accidents and injuries while checking your lawn mower starter.

Disconnect the Spark Plug Wire

Before proceeding with the troubleshooting process, it’s essential to prioritize safety. To avoid any accidental starting of the engine while working on the starter, the spark plug wire must be disconnected.

To do this, locate the spark plug wire on the mower’s engine. Use insulated gloves to grip and carefully pull the boot off the spark plug. You may also need to use a wrench to loosen and remove any retaining bolts or clips holding the wire in place.

Once the wire is disconnected, place it safely away from the spark plug to prevent any accidental contact and reconnection during the testing process.

Remember to always prioritize safety while working on any electrical components of your mower. Failure to do so could result in injuries or damage to your mower.

Remove the Starter

Before you can test the lawn mower starter, you’ll need to remove it from the engine. Follow these steps to remove the starter:

  1. Disconnect the battery cables to prevent any accidental electrical shock or injury.
  2. Locate the starter on your lawn mower. It’s typically located on the side of the engine and is connected to the flywheel.
  3. Use a wrench to loosen and remove the bolts that secure the starter to the engine.
  4. Gently remove the starter from the engine, taking care not to damage any of the wiring or components.

Inspect the Starter

Now that you have the starter removed from the engine, take a few minutes to inspect it for any signs of damage or wear and tear. Look for any cracks or breaks in the housing, and make sure the wiring connections are secure and intact. You should also check the teeth on the starter gear to make sure they are not excessively worn or damaged.

If you notice any damage to the starter or the starter gear, it may need to be replaced. If you’re unsure whether the damage is severe enough to warrant a replacement, consult a professional for assistance.

Test the Starter’s Continuity

With the starter removed, it’s time to test its continuity. This will help determine if the starter is functioning properly or if it needs further attention. Here’s how to test a lawn mower starter:

  1. Set your voltmeter or multimeter to the continuity setting.
  2. Place one probe on the positive terminal of the starter and the other probe on the starter housing.
  3. If the meter shows continuity, the starter is functioning properly.
  4. If the meter doesn’t show continuity, the starter may have a broken wire or other issues that need to be addressed.

Don’t forget to wear insulated gloves and take safety precautions when testing the starter. If you’re unsure about anything, consult a professional for assistance.

Inspect the Starter Gear

As mentioned earlier, the starter gear is a crucial component of the starter system. If the gear is worn or damaged, your lawn mower starter may not work as it should. To troubleshoot a faulty lawn mower starter, you’ll need to inspect the starter gear closely.

To begin, locate the starter gear on your lawn mower. It is typically located near the flywheel and is connected to the starter motor via a bendix. Using a wrench or pliers, remove the gear from the starter motor and examine it for any signs of damage or excessive wear.

If the gear is damaged or worn, it will need to be replaced. You can purchase a replacement gear from your local lawn mower repair shop or online. It’s important to choose the correct gear size and type for your specific lawn mower model to ensure proper functioning.

Tip: While inspecting the starter gear, also check the flywheel teeth for damage. If the teeth are damaged, replace the flywheel as well to prevent future starting problems.

Overall, inspecting the starter gear is an essential step in troubleshooting a faulty lawn mower starter. By identifying and replacing any worn or damaged components, you can ensure that your lawn mower starts reliably every time.

Reinstall the Starter

Now that you’ve tested and inspected the starter, it’s time to reinstall it back into the engine. Make sure the mounting bolts are tightened securely, but be careful not to overtighten them, which could damage the starter or the engine.

Once the starter is properly secured, reconnect the electrical connections, including the battery cable and the starter solenoid wire, ensuring they are tightened snugly. Remember to reattach any brackets or covers that were removed earlier with the appropriate bolts or screws.

Before you reconnect the spark plug wire, double-check all connections and fastenings to make sure everything is in place and secured properly. Once you’re confident that everything is in order, reconnect the spark plug wire to the spark plug.

With the starter now reinstalled, give it a final test to make sure it starts the engine correctly. If you followed all the steps correctly, the starter should work perfectly, and your lawn mower should be ready to go.

Keep in mind that these steps are just a guide, and if you’re not confident in your ability to diagnose or fix your lawn mower starter, it’s always best to consult a professional. But with the knowledge gained from this step-by-step lawn mower starter test, you’ll be well on your way to diagnosing and fixing any starting problems your mower may have.
