Failures are frequently the combination of several factors.  One thing usually 
isn't enough to make something fail.  So running an improper test AND having 
someone read a gauge wrong AND having a relay fail, now that is when you 
powerplant blows up.

I ranted before about the complexity of the modern powerplants- the more 
complex, the more chance of an unforseen sequence of events.  
Battery-switch-lightbulb, now that is a simple system.  Walls full of relays, 
walls full of gauges, those are a little more complex.
