Highlights
- A short circuit in the wiring harness can create a direct path for current to flow, bypassing the fuel pump.
- Damage to the wiring harness, such as cuts or pinching, can expose wires and create a short circuit, leading to a blown fuse.
- By following the troubleshooting and resolution steps outlined in this guide, you can effectively address the issue of the Can-Am Outlander 800 fuel pump fuse blowing.
Are you an avid Can-Am Outlander 800 enthusiast, only to be stumped by a persistent issue of your fuel pump fuse blowing? This frustrating problem can leave you stranded and yearning for a solution. Fear not, for this comprehensive guide will empower you with the knowledge to diagnose and rectify this issue, ensuring your Outlander 800 runs smoothly once more.
Understanding the Fuel Pump Fuse
The fuel pump fuse acts as a safety mechanism, protecting the fuel pump from electrical overloads. When excessive current flows through the circuit, the fuse blows, interrupting the power supply to the fuel pump.
Causes of Blown Fuel Pump Fuse
1. Fuel Pump Failure
A faulty fuel pump can draw excessive current, causing the fuse to blow. Symptoms of a failing fuel pump include reduced fuel pressure, difficulty starting, and engine stalling.
2. Electrical Short Circuit
A short circuit in the wiring harness can create a direct path for current to flow, bypassing the fuel pump. This can lead to a blown fuse and potential damage to other electrical components.
3. Faulty Fuel Pump Relay
The fuel pump relay controls the power supply to the fuel pump. A malfunctioning relay can send continuous power to the pump, resulting in a blown fuse.
4. Corrosion or Loose Connections
Corrosion or loose connections in the fuel pump circuit can create resistance, causing the fuse to blow. This is especially common in areas with high humidity or moisture.
5. Wiring Damage
Damage to the wiring harness, such as cuts or pinching, can expose wires and create a short circuit, leading to a blown fuse.
Troubleshooting the Problem
1. Check for Fuel Pump Failure
Disconnect the fuel line from the fuel pump and turn the ignition key to the “on” position. If fuel does not flow out of the pump, it is likely faulty.
2. Inspect the Wiring Harness
Thoroughly inspect the wiring harness for any visible damage, loose connections, or corrosion. Check for any signs of pinching or cuts that may have caused a short circuit.
3. Test the Fuel Pump Relay
Use a multimeter to test the continuity of the fuel pump relay. If the relay is faulty, it should be replaced.
4. Clean and Tighten Connections
Clean any corroded or loose connections using a wire brush or electrical cleaner. Ensure all connections are tight and secure.
5. Inspect for Wiring Damage
If no visible damage is found on the wiring harness, use a multimeter to test for continuity. If there is a break in the circuit, the wiring harness must be repaired or replaced.
Resolving the Issue
Once the root cause of the blown fuse has been identified, take the necessary steps to resolve the issue.
- Replace the faulty fuel pump.
- Repair or replace any damaged wiring harness.
- Replace the faulty fuel pump relay.
- Clean and tighten all electrical connections.
Replacing the Fuel Pump Fuse
1. Locate the fuse box, typically under the seat or behind the battery.
2. Identify the fuel pump fuse (usually labeled “Fuel Pump“).
3. Use fuse pullers or needle-nose pliers to remove the blown fuse.
4. Insert a new fuse of the same amperage rating.
Tips for Prevention
- Regularly inspect the wiring harness for any signs of damage.
- Clean and tighten electrical connections periodically.
- Use dielectric grease to prevent corrosion.
- Avoid overloading the electrical system with excessive accessories.
In a nutshell: Reclaiming Your Outlander’s Performance
By following the troubleshooting and resolution steps outlined in this guide, you can effectively address the issue of the Can-Am Outlander 800 fuel pump fuse blowing. With proper diagnosis and timely repairs, you can restore your Outlander’s performance and enjoy uninterrupted adventures on the trails.
Frequently Asked Questions
Q: How often should I replace the fuel pump fuse?
A: The fuel pump fuse should only be replaced if it blows. Regular inspection and maintenance will help prevent premature fuse failure.
Q: Can I use a higher amperage fuse to prevent blowing?
A: Using a higher amperage fuse is not recommended. It can allow excessive current to flow, potentially damaging the fuel pump or other electrical components.
Q: What is the cost of replacing a fuel pump?
A: The cost of replacing a fuel pump varies depending on the model and year of your Outlander. Expect to pay between $200 and $500 for the part and labor.
