As true as this is, they do short out sometimes. Heat caused by resistance increasing from a failing connection gets the pigtail plug very hot until something starts to melt.

Last time this happened the plug end was a melted mess.

We are into a long weekend so I have 3 days off. Going to pull it apart and have a look.
