Troubleshooting Guide
Brakes are slow to respond
1. Re-bleed the trailer brakes and actuator.
2. If the trailer is equipped with drum brakes, readjust the drum brakes to
the brake manufacture’s recommended running clearance.
3. Slow response can be caused by trailer wiring that is too small.
4. For trailers where the E/H brake actuator is located less than 10 feet
from the tow vehicle, 12 gage wire is recommended for the black and
white wires between the tow vehicle and the E/H brake actuator. All other
wires should be a minimum of 16 gauge.
5. For trailers where the E/H brake actuator is located more than 10 feet
from the tow vehicle, 10 gage wire is recommended for the black and
white wires between the tow vehicle and the E/H brake actuator. All other
wires should be a minimum of 16 gauge.
6. Slow response can be caused by improper adjustment of the brake
controller. On inertia-based electronic brake controls, adjust the
pendulum (inertia sensor) to a more aggressive setting and/or increase
the gain setting.
Unit will not run when the ignition is on and the brake pedal is depressed
1. Verify that the trailer and tow vehicle are wired as detailed on the
electrical schematic.
2. With the ignition switch on and the brakes not applied, you should
have 12-13 volts between the black and white wires on the E/H brake
actuator.
3. Clean and replace the ground between the trailer and the E/H brake
actuator.
4. Test operation of the unit using the breakaway test procedure.
