JD 210 LE Issues with Brake Stop Light Flashing and Blowing Fuel Gauge Fuse

[MikePhua]

John Deere 210 LE excavator owners have reported issues with the brake stop light flashing and the fuel gauge fuse blowing frequently. These problems can interfere with the normal operation of the machine and might indicate potential issues in the electrical or braking systems. This article discusses these common problems and their possible solutions.
1. Flashing Brake Stop Light Issue
The flashing brake light is usually caused by an electrical malfunction. Some common causes include:

• Faulty Brake Switch: The brake switch may be malfunctioning or have a poor connection. If the brake switch is defective, it could cause the brake light to flash. Testing and replacing the brake switch could resolve the issue.
  
• Loose or Corroded Wiring: A loose or corroded electrical connection in the brake light circuit can result in an unstable signal and cause the brake light to flash. Inspect the wires and connectors for wear and corrosion.
  
• Battery Voltage Issues: If the battery voltage is unstable or too low, it can affect the electrical system and cause irregularities like a flashing brake light. Check the battery voltage to ensure it's stable.
  

2. Fuel Gauge Fuse Blowing
Frequent blowing of the fuel gauge fuse can be caused by a few issues:

• Electrical Short Circuit: A short circuit in the fuel gauge wiring is a common cause of blown fuses. Inspect the wiring for any exposed wires or damaged connections that could cause a short.
  
• Faulty Fuel Sensor: A defective fuel sensor might cause excessive current flow, blowing the fuse. Check the fuel sensor for any internal short circuits or damage.
  
• Overloaded Circuit: If the fuel gauge circuit is overloaded, it could lead to blown fuses. Ensure that there are no additional electrical loads causing an overload in the circuit.
  

3. Solutions
Here are some potential solutions to address the issues:

• Inspect the Brake Switch and Wiring: Test the brake switch to ensure it's functioning correctly. If the switch is defective, replace it. Also, check the brake light circuit for any loose connections or corrosion.
  
• Check Battery Voltage: Measure the battery voltage to ensure it is stable and within the correct range. Low or unstable battery voltage can affect the electrical system, including the brake lights and other electronic devices.
  
• Inspect for Short Circuits and Sensor Issues: Check the fuel gauge circuit for any short circuits and repair any damaged wiring. Also, inspect the fuel sensor to ensure it’s not defective or causing a short.
  
• Replace the Fuse: If the fuse blows, replace it with a new one of the correct rating. After replacing, check the circuit for any underlying issues that could cause the fuse to blow again.
  

Conclusion
The issues with flashing brake stop lights and blowing fuel gauge fuses in the JD 210 LE excavator are common electrical problems. These issues could be related to the brake switch, wiring connections, fuel sensor failure, short circuits, or battery voltage instability. By systematically checking each of these factors, you can pinpoint the source of the problem and take corrective actions to resolve it. Maintaining the electrical system of your excavator will help extend its lifespan and improve its overall performance.
