The controller should be easily accessible and viewable, typically under the steering column. Ensure the mounting surface is stable and allows for secure attachment. Next, connect the wiring harness to the controller, following the specific wiring diagram provided in the manual.
The harness typically includes wires for power, ground, brake signal, and trailer brake output. Connect these wires to the corresponding circuits in the tow vehicle. It’s vital to ensure proper grounding to avoid electrical issues. After wiring, securely mount the controller using screws or brackets. Test the connections by activating the brake pedal and observing the controller’s display. Adjust the controller’s settings according to the trailer weight and braking requirements. Finally, perform a road test to verify the trailer brakes are functioning correctly, making any necessary adjustments to the gain settings for optimal braking performance.
Wiring Guide and Connections
Proper wiring is paramount for a Tekonsha electric brake controller to function correctly. Typically, four wires are involved: power, ground, brake signal, and trailer brake output. The power wire should be connected directly to the vehicle’s battery, often through a circuit breaker, to ensure a consistent power supply. The ground wire must be securely connected to the vehicle’s frame to provide a reliable ground path, preventing electrical interference.
The brake signal wire should be connected to the cold side of the brake light switch, which activates when the brake pedal is pressed. This signal tells the controller when to apply the trailer brakes. The trailer brake output wire runs from the controller to the trailer’s electric brakes, delivering the necessary power for braking. Always refer to the Tekonsha wiring diagram specific to your controller model for correct wire colors and locations. Ensure all connections are secure, using crimp connectors or soldering, to prevent loose connections and potential malfunctions. Double-check the wiring before operating the trailer.
Setting Up and Calibrating the Controller
Proper setup and calibration of your Tekonsha brake controller are crucial for optimal performance. Begin by mounting the controller securely within reach and ensuring the display is easily viewable. Next, adjust the initial power level, usually indicated in voltage, based on the weight and braking capacity of your trailer. Start with a lower setting, around 6V, and gradually increase it during the calibration process.
To calibrate, find a safe, level surface and drive at approximately 25 mph. Manually engage the brake lever on the controller. If the trailer wheels lock up, reduce the power setting. If the trailer does not brake adequately, increase the power. The goal is to achieve firm, smooth braking without wheel lockup. Some controllers have boost settings that can be adjusted to provide additional initial braking power. Select the appropriate boost level based on your towing conditions and trailer brake condition. Regularly check and readjust the settings as needed to maintain optimal braking.
Using the Manual Control Lever
The manual control lever on your Tekonsha brake controller serves a vital purpose, giving you direct command over your trailer brakes. Unlike the automatic braking system, which activates in proportion to your vehicle’s deceleration, the manual lever allows you to apply the trailer brakes independently. This functionality is particularly useful in several situations. During the initial setup and calibration of the controller, the manual lever allows you to test the braking force and adjust the power settings.
It is also helpful in situations where you desire to reduce speed gradually, such as descending a steep hill or navigating slippery road conditions. In emergency situations, the manual lever provides an immediate way to apply the trailer brakes, potentially preventing or mitigating a collision. To use the manual lever, smoothly slide it to the left. The farther you move the lever, the more braking force is applied to the trailer brakes, up to the maximum setting.
Troubleshooting Common Issues
Experiencing issues with your Tekonsha brake controller can be frustrating, but many common problems can be resolved with some simple troubleshooting. One frequent issue is weak or no braking on the trailer. Start by checking all wiring connections to ensure they are secure and free from corrosion. Verify that the brake controller is properly grounded, as a poor ground can cause various problems. If the brake lights on your tow vehicle are not functioning correctly, this can also affect the brake controller’s performance.
Inspect the trailer brake magnets for wear or damage, as they are responsible for applying the braking force. Another common symptom is intermittent error codes or a flashing display. Consult your Tekonsha manual to interpret the specific error code and follow the recommended steps. If the controller displays “OL” or “overload,” it may indicate a short circuit in the trailer wiring or a faulty brake magnet. Always disconnect the trailer plug before testing the breakaway switch to avoid damaging the brake controller.
Adjusting Brake Power and Boost Settings
Fine-tuning your Tekonsha brake controller involves adjusting the brake power and boost settings to achieve optimal braking performance. The brake power setting determines the maximum voltage sent to the trailer brakes during braking. Begin by setting the power level according to the manufacturer’s recommendations, typically found in your Tekonsha manual. To properly adjust, drive on a dry, level surface at approximately 25 mph and use the manual control lever to engage the trailer brakes.
If the trailer brakes lock up, reduce the power setting until they no longer lock. Conversely, if the trailer brakes feel weak, increase the power setting. The boost setting, available on some Tekonsha models like the P3, provides an initial surge of power to the trailer brakes for more aggressive braking. Select the boost level based on your towing situation, driving preferences, and the condition of your trailer brakes. Higher boost levels are suitable for heavier loads or when towing in challenging conditions, while lower boost levels are ideal for lighter loads and smoother braking.
