Default Power from truck through 7-pin harness?

Hi all,

We just returned from our first trip of the season. On the trip, I discovered that I am not getting any power or battery charging through the positive pin on the 7-pin connector. Using a multimeter, I checked the other pins and everything else seems to work. I held the negative pin of the multimeter to the ground pin on the Bargman (truck side) and moved the positive pin to each of the other connectors, engaging lights, etc.. All lights and brake controller are getting power, but 0 volts when I connect my multimeter to the positive/aux pin. I tried cleaning the contact, but no success. Any thoughts or suggestions?

John
