Troubleshooting a Murray Riding Lawnmower: Solenoid Clicks but Engine Won't Start

Introduction

If your Murray riding mower model 38608x92c is clicking at the solenoid but not turning over, it can be frustrating. This article will guide you through potential issues and the steps to resolve them, ensuring your mower starts smoothly.

Understanding the Problem

Your mower's solenoid is clicking, but it’s not turning over. You’ve also checked that the battery is providing over 12 volts, but only 7 volts are reaching the starter terminal. This discrepancy suggests a voltage drop issue. This article will explore the potential causes and solutions.

Potential Issues

Faulty Solenoid

Even if the solenoid is clicking, it might not be functioning properly. The solenoid’s purpose is to create a direct connection between the battery and the starter when engaged. If it’s faulty or has internal corrosion, it might not pass sufficient voltage to the starter.

Wiring Issues

Inspect the wiring between the solenoid and the starter for any signs of damage, corrosion, or loose connections. A bad connection can result in significant voltage drops, which would explain the voltage difference you’re observing.

Starter Motor

The starter motor itself might be the culprit. Internal issues with the starter can lead to excessive current draw, making the solenoid struggle to pass enough voltage.

Ground Connection

Ensure that the ground connection from the battery and the engine block is secure and free of corrosion. A poor ground can lead to insufficient voltage reaching the starter, causing the voltage drop you’re experiencing.

Battery Condition

EVEN THOUGH THE BATTERY IS SHOWING MORE THAN 12 VOLTS, IT’S WORTH CHECKING ITS CONDITION UNDER LOAD. A BATTERY CAN SHOW GOOD VOLTAGE BUT FAIL TO PROVIDE SUFFICIENT CURRENT IF IT IS WEAK OR HAS A BAD CELL.

Troubleshooting Steps

Test the Solenoid

Use a multimeter to check the voltage at the solenoid terminals when the key is turned. There should be battery voltage around 12V on both sides when engaged. If not, the solenoid may need replacement.

Inspect Wiring

Examine the wiring between the battery, solenoid, and starter for any signs of damage, corrosion, or loose connections. A proper inspection will help you identify any issues that could be causing the voltage drop.

Bypass the Solenoid

As a temporary test, you can bypass the solenoid by connecting the battery directly to the starter. This will help determine if the starter is functioning properly without the interference of the solenoid.

Check Ground Connections

Ensure all ground connections are tight and clean. A secure ground is essential for the proper operation of the starter.

Test the Starter

If possible, remove the starter and test it on a bench. This will help confirm whether the starter is operational. If the starter works fine on the bench, there might be an issue with integrating it into the mower’s electrical system.

Conclusion

By following these steps, you should be able to pinpoint the issue preventing your Murray riding mower from starting. If any of the components are found to be faulty, replacement will likely resolve the problem. Troubleshooting your mower can sometimes be a process of elimination, but with the right tools and knowledge, you can get your mower back on track.

Additional Tips

To keep your Murray riding mower running smoothly, regular maintenance is essential. Make sure to replace the battery, check the solenoid, and tighten all electrical connections as part of your routine checks.
