YEP, and we knew it IMMEDIATELY! It did not sound right, NOR look right. Taking no chances we unhooked, and redid the entire procedure. No problem the second attempt. This was the only occurance we have had, but it was a good reminder for us, PAY ATTENTION with your ears and your eyes! And, even tho we know Glenn does not do it, we do, pull test. Probably not necessary, but it puts us in a "comfort zone" knowing we have done so. Maybe when we get to be pros at this we won't do the pull test - - - - NAHHHH, think we will probably ALWAYS do one.
