I will 2nd and 3rd Bens advice. Bad cables have been the huge majority of 
such nefarious goings on. Particularly if they are bright red and 4+ 
years old, put a tail on the log, and prod the cable gently with a 
wooden pencil.  If the log blows up, bad cable, replace it with any 
color but red. Preferably a month ago...
