Troubleshooting continued
Symptom: The brake pedal clamp on the braking system comes into contact with the unit housing.
Solution: Brake pedals that are somewhat horizontal cause the pedal clamp to tilt. This angle causes the pedal clamp
to interfere with the unit housing when it retracts. Use optional pedal extender part number 9336 (1.5 inch) or 9336-3
(3.5 inch) to gain additional clearance from the housing.
Symptom: Nothing happens after proper installation.
Solution: a.) Check fuse on the end of power cord. The braking system unit uses a 20 amp fuse and the BrakeAlert
uses a 10 amp fuse.
b.) Check power at 12 volt outlet with key in towed position. If there isn't any 12 volt power you will need
an optional 12 volt power outlet (part number 9332).
c.) Polarity on 12 volt outlet kit has been crossed. Positive is connected to ground and ground to positive.
This will blow the 20 amp fuse in the end of the 12 volt power cord. You will need to correct the wiring and
replace the 20 amp fuse in the end of the power cord.
Symptom: Braking system is not running.
Solution: Check for red LED light on cigarette plug. Check fuse for towed vehicle. Also, check your battery voltage. If your
battery does not have sufficient power it will put the unit into sleep mode, always make sure your battery has full power.
Symptom: As soon as I plug in the braking system, the compressor starts cycling on and off and the air
cylinder starts pumping in and out (“jack-rabbiting”).
Solution: Simultaneously press and hold the “Max Brake” button and “Brake Sensitivity” button until the row of sensitivity
lights flash three times. This will program level and eliminate the symptom. If the box is not attached to the brake pedal and
in position for towing, then you will have to re-program level again once the box is properly in position. See section titled
“Programming Level” for more details.
Symptom: Braking system’s air cylinder jack rabbits (extends and retracts) repeatedly.
Solution: a) Vehicles wiring is too small or low in power for the unit to operate properly. The braking system requires 15
amps to function properly. Install optional 12 volt power outlet (part number 9332) to supply sufficient power
to the system.
b) This unit needs to be re-programmed for level. See section titled “Programming Level”
Symptom: Towed vehicle seat moves after the braking system depresses the brake pedal.
Solution: The unit may cause the seat to move. To avoid this, make sure the seat is in a locked position when it
is adjusted behind the system’s housing. Readjust the adjustable seat pad and re-test. Depress the test button and hold it until
the cylinder extends to check for proper position and seat stability.
Symptom: The unit rides up the seat.
Solution: Remove the floor mats under the braking system and/or check the position of the adjustable handle.
The handle also serves as an anchor point to keep the unit down as it depresses the brake pedal.
Symptom: Braking system is activating before I want it to, or when I don't think it should be.
Solution: a) Check for level of the unit in the towed car. If level, raise sensitivity number by 1.
b) Reprogram level as described under section “Programming Level”
Symptom: My brakes are applying when they should not be.
Solution: a) Reprogram level as described under section “Programming Level”.
b) The braking system may activate even when you are not depressing the motorhome’s brakes.
This is usually a result of an incorrect sensitivity setting. If you are experiencing unwanted
activation while going down steep grades, increase the number on the Brake Sensitivity to make
the unit activate to your preferences. Jake Brakes and Pac Brakes (that is engine braking
systems) may also cause unwanted system activation which can be solved the same way.
IMPORTANT! THIS DECREASED BRAKING SENSITIVITY SETTING MAY PREVENT THE SYSTEM
FROM ACTIVATING DURING NORMAL LIGHT BRAKING CONDITIONS.
FAILURE TO INSTALL AND OPERATE THE BRAKING SYSTEM AS INSTRUCTED MAY RESULT IN
UNIT TO MALFUNCTION, PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
