What You'll Learn
Common Causes of Fuse Failure
The Can-Am Outlander 800's fuel pump fuse blowing repeatedly is a frustrating issue that often stems from underlying electrical problems. One of the most common causes is a short circuit in the fuel pump wiring harness. Over time, wires can become frayed, pinched, or damaged due to vibration, debris, or improper installation. When this happens, the exposed wires may come into contact with each other or the vehicle's frame, causing a short that draws excessive current and blows the fuse. Inspect the wiring harness for any visible damage, paying close attention to areas near the fuel pump, engine, and frame. If a short is suspected, repairing or replacing the damaged wiring is essential.
Another frequent culprit is a faulty fuel pump itself. If the fuel pump is drawing too much current due to internal damage, worn brushes, or a seized motor, it can overload the circuit and blow the fuse. To diagnose this, disconnect the fuel pump connector and test the fuse. If the fuse no longer blows, the fuel pump is likely the issue. Replacing the fuel pump with a high-quality unit is recommended to prevent recurring problems. Additionally, ensure the fuel pump relay is functioning correctly, as a failing relay can cause the pump to draw excessive power.
Grounding issues are also a common cause of fuse failure. The fuel pump relies on a solid ground connection to operate efficiently. If the ground wire is corroded, loose, or disconnected, it can create resistance in the circuit, leading to overheating and fuse failure. Check the ground connection at the fuel pump and the chassis for cleanliness and tightness. Clean any corrosion with a wire brush and secure the connection properly. A poor ground can mimic symptoms of a short circuit, so it’s crucial to verify this before assuming the pump or wiring is at fault.
Lastly, incorrect fuse rating or low-quality fuses can contribute to the problem. Using a fuse with a higher amperage than specified can lead to overheating and potential fire hazards, while a fuse with a lower rating will blow prematurely. Always use the correct fuse type and rating as recommended by the manufacturer. Additionally, low-quality fuses may fail more frequently due to inferior materials or construction. Investing in high-quality, OEM-approved fuses can provide greater reliability and prevent unnecessary failures. Addressing these common causes systematically will help resolve the issue and ensure the Can-Am Outlander 800’s fuel pump operates smoothly.

Checking Fuel Pump Wiring Issues
When addressing a fuel pump fuse that keeps blowing on a Can-Am Outlander 800, one of the first areas to inspect is the fuel pump wiring. Faulty or damaged wiring can cause excessive current draw, leading to a blown fuse. Begin by locating the fuel pump wiring harness, which typically runs from the fuel pump to the fuse box or relay. Inspect the entire length of the wiring for any signs of damage, such as chafing, cuts, or exposed wires. Pay close attention to areas where the wiring passes through tight spaces or near moving components, as these are common spots for wear and tear.
Next, check the wiring connections at both the fuel pump and the fuse box or relay. Ensure that all connectors are securely plugged in and free from corrosion or debris. Corroded or loose connections can cause intermittent contact, leading to voltage spikes that blow the fuse. If corrosion is present, clean the connectors using electrical contact cleaner and a wire brush. After cleaning, apply dielectric grease to protect against future corrosion and ensure a stable connection.
To further diagnose wiring issues, use a multimeter to test for continuity and resistance in the fuel pump circuit. Disconnect the fuel pump connector and measure the resistance of the pump itself. Compare this reading to the manufacturer’s specifications to determine if the pump is functioning correctly. If the pump is within spec, test the wiring for continuity between the pump and the fuse box. A break or high resistance in the wiring will indicate a fault that needs repair or replacement.
Another critical step is to check for short circuits in the wiring. A short to ground or between wires can cause the fuse to blow immediately upon replacement. With the fuel pump connector disconnected, use the multimeter to test for continuity between each wire and the vehicle’s ground. If continuity is detected, there is a short circuit that must be located and repaired. Common culprits include damaged insulation or wires pinched between components.
Finally, inspect the fuel pump relay and its wiring. A faulty relay can cause the fuel pump to draw excessive current, blowing the fuse. Test the relay by swapping it with a known good one or using a multimeter to check its functionality. Additionally, examine the relay’s wiring for any signs of damage or poor connections. If the relay or its wiring is at fault, replace or repair the components as needed. By systematically checking the fuel pump wiring and related components, you can identify and resolve the issue causing the fuse to blow repeatedly.

Diagnosing Short Circuits in System
When diagnosing short circuits in the electrical system of a Can-Am Outlander 800 that’s causing the fuel pump fuse to keep blowing, the first step is to isolate the circuit. Start by disconnecting the fuel pump connector and replacing the fuse. If the fuse no longer blows, the issue is likely within the fuel pump itself or its wiring harness. Inspect the fuel pump for signs of damage, such as melted wires, frayed insulation, or a seized motor, as these can cause excessive current draw and blow the fuse. If the fuse still blows with the fuel pump disconnected, the short circuit is elsewhere in the circuit, and further investigation is needed.
Next, trace the wiring harness for the fuel pump circuit to identify any visible damage. Look for areas where the wires may be pinched, rubbed against sharp edges, or exposed to heat sources, as these are common points for short circuits to occur. Use a multimeter to check for continuity between the wire and ground at various points along the harness. If the multimeter shows a direct connection to ground, there is a short circuit in that section of the wiring. Repair or replace the damaged wiring and retest the system before proceeding.
If the wiring appears intact, test the fuel pump itself for internal shorts. Disconnect the pump from the harness and use a multimeter to check the resistance between the power and ground terminals. A reading of zero or very low resistance indicates an internal short within the pump, requiring its replacement. Additionally, test the pump’s operation by connecting it directly to a battery (with an inline fuse for safety) to ensure it functions without drawing excessive current.
Another critical step is to inspect the fuse box and relay associated with the fuel pump circuit. Corrosion, loose connections, or a faulty relay can cause intermittent shorts or excessive current draw. Clean the fuse box terminals and ensure all connections are tight. Swap the fuel pump relay with another identical relay in the vehicle (if available) to determine if the relay is the culprit. If the fuse stops blowing after replacing the relay, the original relay was likely defective.
Finally, check for parasitic draws in the system. With the vehicle turned off, disconnect the fuel pump fuse and connect a multimeter in series with the fuse holder to measure current draw. A significant draw (more than a few milliamps) indicates a parasitic load somewhere in the circuit. Systematically disconnect components in the fuel pump circuit until the draw disappears to pinpoint the faulty component. This methodical approach ensures that the root cause of the short circuit is identified and resolved, preventing further fuse failures.
