Introduction
The John Deere 310SE is a popular backhoe loader that has been widely used for various construction and digging tasks since its release. Known for its durability and efficiency, this machine has become a go-to choice for many operators and contractors. However, like any piece of heavy machinery, the 310SE can encounter starting issues that may cause delays and headaches on the job site.
A common problem reported by some 1999 John Deere 310SE owners is that the machine will not crank over or start. This issue can be caused by a variety of factors, ranging from electrical malfunctions to fuel delivery problems. In this article, we will explore the potential causes of this issue and provide a guide to diagnosing and resolving the problem.
Understanding the Starting System in the John Deere 310SE
Before diving into the troubleshooting process, it's important to understand the basic components that are involved in starting the John Deere 310SE. The starting system consists of several key parts:
Common Causes of Starting Problems
1. Dead or Weak Battery
A dead or weak battery is one of the most common reasons a backhoe loader will fail to start. If the battery is not providing sufficient voltage, the starter motor will not be able to turn the engine over. Signs of a weak battery include dim headlights or other electrical components not functioning properly.
Solution:
If the battery is in good condition but the engine still won't crank, the starter motor or solenoid may be the issue. A faulty solenoid may fail to engage the starter motor, while a worn-out starter motor may not turn the engine over effectively.
Solution:
The ignition switch is responsible for sending power to the starter solenoid when you turn the key. If the ignition switch is faulty or worn out, it may not be sending the proper signal to engage the starter motor.
Solution:
A common issue that can prevent the 310SE from starting is a blockage or malfunction in the fuel system. If the fuel filter is clogged, the fuel pump is faulty, or there is air in the fuel lines, the engine may not receive enough fuel to start.
Solution:
The John Deere 310SE is equipped with several safety switches that prevent the engine from starting if certain conditions are not met. For example, the machine may not start if the parking brake is not engaged or if the transmission is not in neutral.
Solution:
Another potential cause of starting issues is a blown fuse or damaged wiring. Fuses protect the electrical components of the machine from overloading, and if one blows, it can interrupt the power supply to the starter motor or ignition system. Damaged wiring can also result in a loss of power to the system.
Solution:
Now that we’ve covered the potential causes, here’s a step-by-step guide to diagnosing and fixing the starting issue:
Step 1: Check the Battery
Start by inspecting the battery. Ensure it is fully charged and that the terminals are clean and tightly connected. Use a multimeter to check the battery voltage.
Step 2: Inspect the Starter Motor and Solenoid
If the battery is fine, test the starter motor and solenoid. Bypass the solenoid to see if the motor works, and replace the faulty part if necessary.
Step 3: Test the Ignition Switch
If the starter motor and solenoid are working, check the ignition switch. If the switch is not sending power to the solenoid, replace the ignition switch.
Step 4: Inspect the Fuel System
Check the fuel system for any blockages or issues. Replace the fuel filter, inspect the fuel lines, and ensure the fuel pump is functioning properly.
Step 5: Check Safety Switches
Make sure all safety switches are engaged and functioning correctly, including the parking brake and transmission neutral switch.
Step 6: Check Fuses and Wiring
Inspect all fuses and wiring for any signs of damage. Replace any blown fuses and repair any damaged wiring.
Conclusion
Starting issues in the 1999 John Deere 310SE can be caused by a variety of problems, ranging from a dead battery to faulty wiring. By systematically checking each component in the starting system—battery, starter motor, ignition switch, fuel system, and safety switches—you can identify and resolve the issue.
Regular maintenance and inspection of the machine’s electrical and fuel systems can help prevent these issues from occurring in the future. If the problem persists despite following these troubleshooting steps, it may be worthwhile to consult a professional mechanic or John Deere technician for further assistance.
By addressing starting issues promptly, you can keep your John Deere 310SE running smoothly and ensure that it remains a reliable tool for your construction and digging projects.

Understanding the Starting System in the John Deere 310SE
Before diving into the troubleshooting process, it's important to understand the basic components that are involved in starting the John Deere 310SE. The starting system consists of several key parts:
- Battery: The battery provides the electrical power necessary to turn the starter motor and engage the engine.
- Starter Motor: The starter motor is responsible for cranking the engine, allowing it to begin running.
- Solenoid: The solenoid is a type of relay that connects the battery to the starter motor and triggers the cranking process.
- Ignition Switch: The ignition switch is used to turn the machine on and off. It sends the signal to engage the starter motor when the key is turned.
- Fuel System: The fuel system is responsible for delivering fuel to the engine. If there is a blockage or issue in the fuel delivery system, the engine may fail to start.
Common Causes of Starting Problems
1. Dead or Weak Battery
A dead or weak battery is one of the most common reasons a backhoe loader will fail to start. If the battery is not providing sufficient voltage, the starter motor will not be able to turn the engine over. Signs of a weak battery include dim headlights or other electrical components not functioning properly.
Solution:
- Check the battery voltage with a multimeter. A fully charged battery should read around 12.6 volts.
- If the battery is low, try charging it or replacing it if necessary.
- Inspect the battery terminals for corrosion or loose connections. Clean the terminals and tighten the connections if needed.
If the battery is in good condition but the engine still won't crank, the starter motor or solenoid may be the issue. A faulty solenoid may fail to engage the starter motor, while a worn-out starter motor may not turn the engine over effectively.
Solution:
- Test the starter motor by using jumper cables to bypass the solenoid and directly connect the starter to the battery.
- If the starter motor turns over but the engine doesn’t crank, the solenoid or starter may need to be replaced.
- If the starter motor does not turn over at all, the motor itself may be faulty and should be replaced.
The ignition switch is responsible for sending power to the starter solenoid when you turn the key. If the ignition switch is faulty or worn out, it may not be sending the proper signal to engage the starter motor.
Solution:
- Test the ignition switch by turning the key and checking if power is being sent to the starter solenoid.
- If there is no signal from the ignition switch, the switch may need to be replaced.
A common issue that can prevent the 310SE from starting is a blockage or malfunction in the fuel system. If the fuel filter is clogged, the fuel pump is faulty, or there is air in the fuel lines, the engine may not receive enough fuel to start.
Solution:
- Check the fuel filter for clogs and replace it if necessary.
- Inspect the fuel lines for any leaks, cracks, or blockages.
- Ensure the fuel pump is working by checking the fuel pressure.
- Bleed the fuel system if there is air trapped in the lines.
The John Deere 310SE is equipped with several safety switches that prevent the engine from starting if certain conditions are not met. For example, the machine may not start if the parking brake is not engaged or if the transmission is not in neutral.
Solution:
- Ensure that the parking brake is fully engaged.
- Verify that the transmission is in the neutral position.
- Check all safety switches and bypass them (if necessary) to test if any of them are malfunctioning.
Another potential cause of starting issues is a blown fuse or damaged wiring. Fuses protect the electrical components of the machine from overloading, and if one blows, it can interrupt the power supply to the starter motor or ignition system. Damaged wiring can also result in a loss of power to the system.
Solution:
- Inspect the fuses and replace any that are blown.
- Check the wiring for any signs of damage, wear, or loose connections.
- Ensure all electrical connections are clean and tight.
