Also Yes, on my new factory, one of the m/f "fast-on" pins was just barely started in the connection , believe it was the yellow, not pushed in all the way. It has a soft plastic shroud , so tricky to see. Another check, make sure the wire insulation got stripped before the m/f "fast-on" got crimped. Have seen this before, on other equipment. The pin connector barrel crimp does nothing in this case, and the small pointy sharp insulation grab hooks are the only thing that makes a connection with weird results following time as it corrodes/oxidizes , with possible intermittent results.
