Thanks for the feedback. In retrospect, as mentioned I believe I started using it after some oxidation had already occurred and the extra lubrication and non conductive nature of the grease prevented a good connection. Also as mentioned, my 7 pin connector does not feel very tight. I don't think it's wiping the grease off as it goes in.
It's interesting that sometimes something that seems so simple can present a problem when you least expect it. But all is good, I got it cleaned up and we are on location after an uneventful trip. Thanks for the help. I just keep on learning.
