Power Cord Stuck in Trailer's Electrical Socket
The last time I went camping in our Grand Surveyor 5th wheel the main (shore-to-trailer) 30 amp power cord would not separate from the trailer's power inlet box. This has never before happened. As usual, after disconnecting water, packing up, pulling in slide, hitching trailer to truck, etc., I turned off the circuit at the campsite's power post. I then unplugged the cord from the post. Then I went to the trailer, grasped the safety ring that secures the female end of the power cord to the trailer's male inlet, and turned the ring counter-clockwise a couple of turns until it was loose. Finally I grasped the end of the plug and turned it slightly to the left to "unlock" it, and tried to unplug it. The plug would not budge no matter how hard I pulled on it. I thought about severing the power cord from its plug in order to leave the campsite, but decided the wiser action was to leave the cord plugged into the trailer's power inlet and secure the 30' cord to the ladder on back of the trailer. That way when I arrived at my house I was able to plug into a home outlet to keep the trailer's battery charged.
I do not like the idea of always traveling with the power cord attached to the ladder. So now how do I diagnose and fix the problem? (Of course the first thing will be to disconnect the trailer from any electrical source.) Should I unscrew the power inlet from the trailer? Will it come off easily? Will there be enough wire to pull out the inlet far enough to examine whether the problem is with the male prongs or the female plug on the power cord? Maybe they somehow got bent together so now I must replace both. Any suggestions or recommendations? Thanks.
