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.
