Ajo Aridzona September 1988
Looser-n-a-goose receptacle and it was 108F. Temper flared.
Two Vice-Grips. Grabbed the prong base with the needle nose, and SLIGHTLY tweaked the conductors with the standard pair. By slight, I mean some folks may not have the "touch". The "fix" is a twist and not a spread of the prongs.
I shut off the rig master breaker. Then pushed and pulled the genetically modified plug into the receptacle several times to do the best I could cleaning purple and black contacts. This was a huge park and the only trees were tall shrubs and the office was a 200 meter walk. The breakers were under lock and key.
If what I did had "ruined" fully annealed rotten brass contacts inside the receptacle - I just saved the next guy the hassle of a plug. The modified plug went in and out of my home receptacle a bit stiff a few hundred times, but when I changed it to the RV Park post, I got complimented from a camper about how nice the hookup was.
Verbal comments to management are like screaming at the wind. Write down a polite comment to park management.
I do exactly the same thing to 15-amp receptacles - only now, I'll wet the prongs with DeOxit D100 for a tight but nasty receptacle. I use home made CHEAP PRICE extensions and save the actual cord plug.
