2.2 Connecting the Wiring Harness
Connect the wiring harness to the vehicle’s electrical system, ensuring all wires are securely attached. The brake controller’s wiring harness includes connections for power, ground, brake input, and trailer brakes. Connect the ground wire to a clean, bare metal surface to avoid electrical interference. Attach the brake output wire to the trailer connector, ensuring proper polarity. Use the manual slide knob to test the brakes before towing. Avoid overloading the controller, as this can cause malfunction. Ensure all connections are tight and protected from moisture for reliable operation. Refer to the wiring diagram in the manual for specific instructions and verify connections before use.
Operation and Adjustment
The Primus IQ Brake Controller operates proportionally, adjusting trailer brakes based on vehicle deceleration. Use the manual slide knob to fine-tune braking sensitivity for optimal performance.
3.1 Understanding Proportional Braking
Proportional braking ensures your trailer’s brakes apply in sync with your vehicle’s brakes, proportionally matching deceleration force. This system enhances control, especially during sudden stops, by adjusting brake pressure seamlessly.
3.2 Adjusting the Manual Slide Knob
Adjusting the manual slide knob on the Primus IQ Brake Controller allows for precise control over the trailer’s brakes. To begin, ensure the trailer is properly connected and in a safe testing area. Locate the manual slide knob, typically situated near the boost button on the controller’s front. Start with a low setting and gently slide the knob to apply the brakes manually, useful for backing up or testing. Gradually increase the adjustment if more braking power is needed. After each adjustment, test the brakes to ensure smooth stops. If the trailer stops too abruptly, reduce the setting. For heavier loads, consider using the boost feature, which enhances braking power. Always test thoroughly after adjustments and consult the manual for guidance on interacting with proportional braking and boost features. Regular testing and fine-tuning will ensure optimal braking performance tailored to your trailer’s load and towing conditions.
Troubleshooting Common Issues
Troubleshoot the Primus IQ Brake Controller by addressing flashing lights, which often indicate ground connection problems or overload issues. Ensure proper wiring and mounting angles for optimal performance.
4.1 Diagnosing Flashing Lights on the Controller
Flickering lights on the Primus IQ Brake Controller often signal issues like a bad ground connection or system overload. Ensure all wires are securely connected and free from corrosion. Check the ground wire, as a loose or corroded connection can cause erratic light behavior. Additionally, verify that the controller is mounted at the correct angle, as improper positioning may trigger false alarms. If the lights continue to flash after these checks, refer to the troubleshooting section for advanced diagnostics or consider consulting a professional technician to resolve the issue effectively and ensure safety while towing.
4.2 Resolving Ground Connection Problems
A stable ground connection is crucial for the Primus IQ Brake Controller to function correctly. If you suspect a ground issue, start by inspecting the ground wire for any signs of damage or corrosion. Ensure it is securely attached to a clean, bare metal surface on the vehicle’s frame. If the connection is loose, tighten it firmly. For corrosion, use sandpaper to clean the contact points and reconnect. If the problem persists, consider relocating the ground wire to a more stable location. Proper grounding ensures reliable operation and prevents erratic behavior such as intermittent braking or false error lights. Always refer to the manual for specific grounding recommendations to maintain optimal performance and safety.
Maintenance and Care
Regular checks ensure optimal performance. Clean dust and dirt from the controller. Verify all connections are secure. Replace worn components promptly. Schedule professional inspections annually for reliability and safety.
5.1 Regular Checks and Updates
Regular maintenance ensures your Primus IQ Brake Controller operates efficiently. Check wiring connections for damage or corrosion and clean the controller periodically to remove dirt and debris.
