Hi
I had a resistor short through its outer cover ( painted carbon film ) and 
take
out a 90 volt line in a pinball machine display. It seemed to have been also 
enhanced
but some old dust that was attracted to the 90 volt lines.
When in the military, I had carbon comp resistors reduce value by as much
as 50% but I've never seen one that wasn't run above its rated voltage
short from end to end.
1/4W resistors don't like 6KV and 1 amp supplies. The arc created might 
count
as a short.
