This is really interesting and scary! Being from California, I was not aware of the potential electrical safety issues with degraded engine block heaters. Thanks Mike for bringing it to our attention!

Could the issue also be the brother inlaw wired the non GFC incorrectly? Or just didn't bother hooking up the ground connection?
