This thread just made me go WOOW !

Unbelievable misinformation coming from a dealership whose job is selling/servicing trailers. Luckily it will be a cheap and easy fix.

If I understand correct, you pulled the pin on the breakaway switch when parking your trailer. If the box melted anytime after that, you shouldn't have been able to reinsert the pin when hooking up to drive home.
It does sound like he pulled the pin while at the campground, then reinserted it just as he left for home. The box would have still been hot, so he could have got the pin back in, but then it would have melted as well, thus getting stuck.

I have read warnings on these breakaway switches (and on electric brake controllers) to not ever pull the pin while hooked to your tow vehicles 12 volt system, as this 'could' create an overload backfeed.
I don't know what kind of "backfeed" you are suggesting, as this is just a simple 12 volt system.

Take it back to the dealer and make sure you talk to someone with some knowledge and tell them what the dumb PDI guy told you to do, if he does not find this wrong you are talking to the wrong person.
They should pull all the hubs and check the magnets for burning also checking the wiring for signs of over heating, the switch obviously needs to be replaced and I would make them do a load-test on the battery as it has had quite a workout over the weekend. All of this should be done at the expense of the dealer because they are ultimately responsible for this.

This is exactly correct and I agree 100%
The switch that melted is an EMERGENCY brake and NOT a parking brake
as everyone else has stated.
It probably melted because it was defective but still should NOT be used
day to day.

The bold print above is mine and it's important.
Good luck and please let us know how this turns out at the dealer!

Every trailer I've owned has been like this from the factory, as it is not tight against the frame and can swivel according to the pull on the cable. On my 5er, I put tension on the cable and then tightened the screw holding it in the proper alignment. The other trailers, I left it loose to swivel.

This is taken from Tekonsha's website on the Voyager brake controller, particularly # 3:

Important Facts to Remember
1. Do not mount or activate RF generating items (cell phones, two way radios) near (less than 12") the brake control.
2. Reversing the connection to a breakaway battery on the trailer will destroy the brake control.
3.Disconnect trailer plug from the tow vehicle prior to testing a breakaway switch, or you may destroy the brake control.
4. The light is:
  • GREEN when trailer is connected.
  • RED when brake pedal or manual is activated and trailer is connected.
5. The GREEN light draws 10 milliamperes of current from tow vehicle. It would take over 5,000 hours to drain the tow vehicle battery.
6. The level adjustment is CRITICAL. The level adjustment determines whether automatic braking response is delayed or aggressive.
7. This brake control is activated by inertia. It senses deceleration and generates an output that reflects the inertia sensed. In a stationary state, the brake control will not apply the trailer brakes unless the Manual Slide Knob is actuated.
8. For Technical Assistance and Warranty Information call: 1-800-786-7968.
For more information and Troubleshooting Check out Tekonsha's Website.

My very simplistic understanding of a basic electric brake proportional controller (and it may be wrong) is this. You would have a 12 volt input from the Tow Vehicle on side A of the brake controller. The controller takes this 12 volts and then applies in proportion how much it needs to stop the trailer on the output side B, which is where the trailer brakes get their power.. The controller changes the voltage to the output to change the amount of power being applied to the magnets in the electric brakes.

Now, if you pull the breakaway pin, while still plugged into a tow vehicle, you are now applying 12 volts from the trailers battery back up side B, which is the output side of the brake controller......thus backfeeding the power to the controller.

#3 is very important.
My prodigy controller has the very same warning.

Well that's kindof dumb. You would think the brake controllers would have some form of protection for that.

I believe some do and some don't. That's why we want to err on the side of caution and others may learn from reading this thread.

I was just thinking about the time my emergency brake cable snagged on something in the truck bed and got pulled out. That would have fried one of these expensive unprotected controllers.
I was lucky that I just had a cheap one at that time, and nothing happened.
