So,I was standing at the kitchen counter getting a bowl of ice cream and notice a brite light just outside the kitchen window. I pull the curtain back and notice the brite light is coming from the front of my truck. I run outside and yank the extension cord from the block heater cord and then run inside the garage and it did pop the breaker. I grabbed the flashlight and step stool (because the friggen truck is too darn tall) and started inspecting the block heater cord and found NO chaffing or bare spots. Inspected the cord end and it burnt off 2 (1 hot and the center ground) terminals. It looks as though there was water dripping off the truck and onto the cord. I have had several diesels and plugged them all in when cold but have never had this happen. Has anyone else or is Murphy's Law just kicking me all day and this was the icing on the cake? :{ Off to the dodge store to get another friggen cord!
