Super scary.  The electricians found a very small bit of blackened wood and burnt wires at te old transformer for the doorbell that stepped the electric down from 110 to 12v. 

This, along with some other conditions, caused the electrician to comment a few times “I’m surprised they didn’t have a fire here”. 

Well, sir, there WAS a fire once – just a super tiny one that could have been Sooo much worse. 

The transformer.  It’s not supposed to look like that….
