Tow Ready Pulse Preventer by Draw-Tite, Hidden Hitch and Reese
When towing (in most applications) with Hazard flashers on, the Digital Display will flash with the Hazard Flashers. If the Brake Control is set aggressively, pulsing may be felt in the trailer brakes. The Pulse Preventer will isolate the Brake Control from the flashers and eliminate the flash/pulse situation.
- For use with most Solid State Electronic Brake Controls
- Required when the brake control unit must be set to higher output levels and driving with "hazard flashers" is necessary
- Pulse Preventer is not necessary for vehicles that have a different bulb for the stop and turn signals (amber turn signals)
Tow Ready # 20501

- Brake Controller Pulses Brakes with Flashers on a 1997 Ford F-250
- The pulse preventer, part # 5501, should stop this problem. The flashers are sending feed back into the brake controller and pulsing it.
Find the spot where the brake controller is spliced into the wire from the cold side of the stoplight switch. This is typically the red wire on the brake controller.
Then just past this (away from brake controller) cut the vehicle stoplight wire and install the Pulse Preventer inline with the yellow wire on the side that the stoplight switch and brake con

- Draw-Tite Activator Trailer Brake Controller Only Works with Manual Override on a 2008 Toyota Tundra
- This sounds like a common ailment that can happen to any brake controller on many different vehicles. The red wire on the brake controller is used to sense when you are stepping on the brake. When it does not work but the manual override lever does, it usually means that the red wire is not connected to the correct wire on the vehicle.
What you will need to do is use a circuit tester, like # 3808, to find the correct wire on the brake switch, located above the brake pedal. There can be more t

- How to Eliminate Tow Vehicle Brakes Activating When Flashers are Used With Electric Brake Controller
- When flat towing a vehicle using an electric brake controller and the flashers are turned on, the flashers will send a matching pulse back into the brake controller and light up the tow vehicle brake lights and if the brake controller is set aggressively may pulse the tow vehicles brakes.
To eliminate that from occurring you will need the Draw-Tite Pulse Preventer, part # 5501. The Pulse Preventer will isolate the brake controller from the vehicles flashers. This part will install where the b

- Troubleshooting Pulsing Trailer Brakes Using a Hidden Hitch Pilot Brake Controller
- I spoke with my contact at Hidden Hitch about the problems you are having with the Pilot Brake Controller, # 80550. First, a pulse preventer will not be needed because the problem you are describing does not seem symptomatic of the issues that would necessitate a pulse preventer.
What you can do is test the brake controller with a multimeter, like # BTMT15, with the vehicle sitting still. You should get a constant 12 volts on the red wire when you step on the brakes and no voltage when not st

- How to Wire in an Electric Trailer Brake Controller Pulse Preventer
- To install pulse preventer, # 5501, you will be installing inline on the vehicle brake output or cold side wire after the connection point where the brake controller is spliced in.
Basically, the brake controller red wire will be attach to the cold side of the brake switch. On this same wire, you will install the pulse preventer. After the connection point of the brake controller, cut the wire that leads to the brake lights. Attach the end closest to the brake controller to the yellow wire an

- How Does the Draw-Tite Pulse Preventer Work
- The pulse preventer, # 5501, works in much the same way as a diode. Basically it allows a signal to only pass through one way on the circuit it is attached to. In this case the signal that might try to backfeed would be the hazard signal on a vehicle that has combined brake lights and turn signals.
The pulse preventer is not needed if the vehicle has separate bulbs for turn signals and brake lights, if you are NOT towing with the hazards on, or in some cases when the brake controller is not s

- Pulsating Brake Performance with a Draw-Tite Activator II Brake Controller
- There could be many possibilities that are causing the pulsating of your brakes on your 2013 Ford F150. A few possibilities to start with would be to use a circuit tester like the Quickee Tester, part # 3808, and check the connection of your stoplight wire from the brake controller to your stoplight switch. This wire needs to be connected to the cold side of the stoplight switch, which will only show power when the brake pedal is applied.
You will also want to check all the connections of the
