Your riding mower’s battery not starting is one of the most frustrating things that can happen to any mower operator. This can happen due to several reasons like a weak battery, corroded or loose connections, and many more. However, don’t despair; there are several troubleshooting tips you can try to fix the issue.
Check the Battery Voltage
Begin by checking the battery voltage. The battery should read a minimum of 12V DC. If the battery reads below 12V and it’s been several years since its last replacement, it might be time for a new battery.
Loose or Corroded Connections
Check the battery connections, particularly the connections to the starter and ground. Sometimes all it takes is a loose connection or a buildup of corrosion to interrupt the flow of power to the starter. Clean any corrosion buildup, and ensure that all wires are connected tightly to their respective terminals.
Check the Starter Solenoid
If connections are okay, the problem could be with the starter solenoid. Take the time to test the starter solenoid for proper function by using a voltmeter. Set the meter to DC voltage and touch the negative lead to the solenoid’s metal frame. Then turn the mower’s key and check whether voltage shows up on the solenoid’s positive post. If it’s dead, then it’s time to replace the starter solenoid.
Test the Battery with a Load Tester
Another way to determine if your battery is the source of the problem is to test it with a load tester. The tester applies the same load that would occur when starting the engine. This test is necessary when the battery seems okay but still fails to start the mower. If the battery shows signs of weakness, you should consider replacing it.
Clean the Carburetor
If none of the above fixes work, it may be time to check the carburetor. Degraded or stale fuel left in the carburetor can cause the engine not to start. Try removing the carburetor and cleaning it with carb cleaner to solve the problem.
Call a Professional
If all else fails, or you’re not mechanically inclined, it might be time to call professional help. Mechanics are trained to diagnose the problem and could save you a great deal of time and money in the long run.
In summary, these are some of the troubleshooting tips for your riding mower’s non-starting battery. Remember to take safety precautions when working with the mower and always disconnect the battery before making any repairs. By following these tips, you should be able to get your mower back out into the yard in no time.
