Trailer hook up melted

+1 SC for Huskers....find the cause and repair it

Originally posted by podwerkz Yeah if the index 'ridge' is worn down (say from being dragged on the road) it might allow the pug to be inserted incorrectly....but when they are new or at least in good condition, it should take a fair amount of force to insert one the wrong way... That's my story and I'm sticking to it!

+1. And if youve been dragging your connector on the road there is probably more missing than just the "ridge". The time that happened to me I had half a connector left after less than half a mile.

My wife managed to get it plugged in "sideways" so that the brakes came on every time she turned the lights on.

Did you have your battery disconnected at some point? Is it possible that when you connected it again, that you got the polarity backwards? I think that would be a possible explanation of what happened. Please check the battery connections to make sure they were/are correct. Check the two 40A fuses in the power center. If they are blown, then it is highly likely that the polarity was reversed at some point.
